Series 3 - Packaged Firetube Boiler
Save Thousands Of Dollars
Over The Life Of Your Boiler
Long-term energy and maintenance efficiencies are the
focus of Burnham quality engineering. When choosing
a boiler, it’s a good idea to select a product with these
features in order to reduce enormous hidden costs down
the road. Review our wetback versus dryback literature for
cost savings.
Boiler Costs Is Not Jus A First Year Proposition
With any ordinary boiler, expenses such as fuel,
maintenance, and repair costs can escalate as the years
go on. Burnham packaged boilers are designed to diminish
these significant expenditures.
Burnham’s High Life-Cycle Efficiency
While most competitive boilers can give fuel-to-steam
efficiencies of 80% or over—when they’re new—how
consistently can they be expected to maintain this level
of operation? Burnham wetback boiler performance will
not drop due to deteriorating rear refractory, leaking door
baffles and seals, and heat-stressed rear tube sheet
as can happen with some drybacks. Easy access is a
necessity for those with heavy refractory, since they need
frequent and expert maintenance.
The Burnham Wetback Saves
Big Money On Maintenance
Over the life of a dryback, brittle refractory baffling and
rear door gasketing will require continuous monitoring,
maintenance, and replacement, costing thousands upon
thousands of dollars. These built-in maintenance costs can
eventually equal or exceed the original cost of the boiler.
As refractory deteriorates, leaking hot gas causes boiler
efficiency to drop until the condition is noticed and the
repairs can be made. Expensive flue temperature alarms
are offered with some drybacks to monitor this dangerous
and costly potentiality. The rear door itself can become
heat-distorted, requiring an expensive replacement. In
addition, boiler downtime during repairs can mean crippling
losses.
This waste of time and money is eliminated with the
Burnham Wetback. The actively functional water jacket
eliminates the need for: refractory wall, rear door, rear
door inspection and sealing, door swing space, and flue
temperature alarm. These costly maintenance headaches
are gone, while boiler performance is increased. Burnham
has only a small, inexpensive refractory area in the burner
area, for burner mounting. The rear access door liner is a
ceramic fiber insert that contains no refractory.
The furnace and rear turnaround area are cool running, fully
wetbacked radiant heat transfer surfaces. They promote good
internal water circulation and rapid heat absorption. There is no
need for the forced internal circulation pumps often specified to
cool the rear tube-sheets and drybacks.
The Burnham Wetback Is Built To Last
Typical dryback boilers have a common rear tubesheet that
expands and contracts at different rates adjacent to each
tube pass, stressing tube ends and increasing the likelihood
of leaks. Additionally, the heavy refractory used in some
drybacks reflects intense heat to the rear tube ends and tube
sheet, accelerating their deterioration. In attempts to stop
leaking, the rear ends of tubes have sometimes been welded.
Cleaning or tube replacement involves opening both the front
and rear covers and resealing them when the job is done.
Usually, if tubes have been welded at the ends, the welds must
be burned out, the tube sheet repaired (or a new segment
welded in) and the new tubes welded.
These costly expenditures are not an issue with the Burnham
Scotch Marine: separate rear tube sheets from each pass
to expand and contract at its own rate without tube-to-sheet
stress. Tubes are rolled and flared in low-pressure units; and
rolled, flared and beaded in high-pressure units. No welding
of tubes is permitted, nor is it necessary. Any eventual tube
replacement is simply a mechanical operation, no welding
involved. The end result is less cost and less headache.

Thermal Efficiency
The effectiveness of the boiler as a heat exchanger. It is the ability of the boiler to exchange heat through tubes and
furnace, by radiation, conduction and convection, to the transfer medium (water). A few of the factors affecting thermal
efficiency are heating surface, tube number and diameter, furnace tube length and diameter.
Combustion Efficiency
This is a measure of the ability of the burner to effectively and completely burn the fuel, coupled with the thermal
efficiency of the boiler. Burners requiring high amounts of excess air to provide flame stability will be less efficient.
Combustion efficiency does not take into account heat loss to the surrounding air through the boiler jacket and piping.
Fuel to Steam Efficiency
Sometimes referred to as overall efficiency. This is a ratio of heat output to heat input. This includes boiler jacket and
piping losses to the surrounding environment. It is the percent of useable heat in the steam (or hot water) compared to
the heat input supplied by the burner. It is also defined as the combustion efficiency less boiler jacket and piping loss
(radiation and convection losses). Since fuel-to-steam efficiency reflects the portion of actual usable heat supplied to
the system, it is most useful when comparing performance of similar equipment, or when doing fuel savings analysis.
BOILER RATINGS
Ratings may be expressed
in the following units:
BHP = Boiler Horsepower. One BHP is the evaporation of 34.5 lbs of 212°F water per hour into dry saturated steam at the same temperature.
BTUh
BHP =
33,475 BTUh/BHP
BTU = British Thermal Units: that quantity of heat required to raise one (1) lb. of water one (1) degree on the Fahrenheit scale. BTUh = BTU/hr.
MBH =1000 BTUh
PPH = Pounds of steam per hour
MBH
PPH =
0.9703 MBH/PPH
Gross Rating – The full output of a boiler actually available to the heating or process system at the outlet nozzle. The Commercial Steel Boiler Industry catalogs gross output as 80% of input.
Net Ratings – The net connected design load that can be supplied with heat by a boiler of given output, allowing for normal system piping losses and pickup from a cold start. Since steam system piping losses may be expected to be larger than for water systems, and steam boilers require greater heat input from a cold start than water boilers before heat flows to the system, steam net ratings for automatic fired boilers are slightly lower in relation to gross output than water net ratings. Hand fired net water and steam ratings are equal and are lower in relation to gross output in order to provide ample allowance for rapid pickup from a banked fire.
MBH net water = Gross MBH x 0.87
MBH net steam = Gross MBH x 0.776
Square Foot Ratings – Net ratings based on a heat emission rate of 240 BTUh per square foot of radiation for steam, and 150 BTUh per square foot for water.
Square Feet Net Steam =
Steam Net MBH
Square Feet Net Water =
0.24 MBH / sq. ft.

Wetback Design vs. Hard Refractory
Dryback Design
Why is a Wetback design better?
Burnham’s three-pass wetback design has a rear water
wall, which separates the primary heating surface of the
combustion chamber from the rear tube sheet. The water
jacket eliminates the need for a refractory wall and rear
door swing space behind the boiler, as well as costly
refractory maintenance. The rear water wall eliminates the need for gasketing,
which is vulnerable to the temperature generated in the
rear of the turnaround area. A wetback design boiler not
only overcomes these expensive deficiencies, but it has
great overall efficiency and virtually maintenance-free
construction. A Burnham boiler will cost you less over the lifetime
of the boiler because it is better by design! Some Points to Remember:
Wetback Advantages
•
•
•
•
•
•
Wetback boilers have separate tube sheets between all major temperature changes.
The rear access door is constructed of lightweight ceramic fiber
The rear doors require no cool-down period and can be opened immediately
No space consuming area required for the swing door
The split rear flue doors are easily removed
Efficiency is readily maintainable because the design of the boiler promotes complete and even circulation of flue gases
Dryback Disadvantages
•
•
•
•
•
Flue gas temperature differential of 1300F-1600F between the second and third passes creates damaging stresses on the single tube sheet. The cost of rear door refractory replacement (approximately every three years) will drastically increase operating costs, as well as the costs associated with yearly rear door gasket replacement. Opening and resealing the rear door is time consuming and requires a 24-hour cool down period prior to opening The heavy refractory may sag on the davit and must be rigged back into place. Heavy jacks or expensive rigging may be required just to open and close the rear doors
Exposing the refractory to hot flue gases can cause erosion and destroy the baffle; resulting in the uneven circulation of flue gases and lower efficiency
Rear refractory walls radiate unabsorbed heat, leading to external heat loss
15
WHAT IS FUEL-TO-STEAM EFFICIENCY AND IS IT IMPORTANT?
Fuel-to-steam efficiency is very important because it is the only true measure of overall packaged boiler operational
efficiency. True fuel-to-steam efficiency takes into account radiation and convection heat losses, which less reputable
manufacturers may ignore. We suggest purchasing your boiler from a manufacturer who guarantees fuel-to-steam
efficiency in the performance of your entire packaged boiler. Be wary of misleading efficiency terms, such as “thermal
efficiency” or “combustion efficiency”. Contact your local Burnham Commercial sales representative for further definition.
MAINTAINABLE EFFICIENCY VS. ATTAINABLE EFFICIENCY
When looking at efficiency as criteria for purchasing a boiler, especially fuel-to-steam efficiency, the manufacturer’s
design efficiency sets theoretical fuel costs while operation efficiency determines actual fuel costs. There is a difference between attainable efficiency and maintainable efficiency. Correct burner adjustments are the key to maintainable efficiency. It is a compromise between the optimum and the practical. Good burner tuning is achievable only with
a good burner design and a good burner/boiler package. WILL A DRYBACK BOILER COST MORE TO OWN?
The answer is simple…Yes! The high cost of maintenance is the biggest consideration in overall efficiency in a dryback design. Consider this example: an average 300 HP boiler operating under normal conditions with a conservative lifespan of 25 years. Our surveys have shown that during this boiler’s lifetime the rear door refractory would be
replaced about 8 times (roughly every three years). Also, assuming the boiler is opened only once a year for inspection, regasketing of the rear door would occur 25 times.
How much cheaper is the hard refractory backed boiler?
So, somebody is offering a hard refractory backed boiler design for less money than a wetback design! While it may
make your initial capital investment costs look great, what does it do to your pocketbook in the long run? Let’s take a look....
Average cost for replacing rear door hard refractory: $6,000
Average cost of regasketing the rear door: $500
Apply these costs to the average lifespan of the boiler:
$6,000 X 8 = $48,000
$500 X 25 = $12,500
Compare the costs of replacing the rear door gasket of your wetback design:
$30 X 25 = $750
The difference between the hard refractory dry back maintenance and the wetback maintenance is
$60,500 - $750 = $59,750.
Now comes the shocking part...for the same amount of money spent in dryback maintenance:

Low NOx
America’s Boiler Company
Combining these three features contribute to an ideal
low NOx package application.
Burnham Commercial has been designing and
producing boilers for 140+ years, and we sell and
service through the largest and most experienced
network of sales representatives in the country. Our
representatives are capable of providing technical
assistance, competent pricing, start-up, and long term
servicing. It’s no wonder we are America’s Boiler
Company!
Our firebox design provides
the largest furnace possible in a firetube, and our
scotch boilers have some of the largest furnaces
available in our market—meaning we can meet all
your Low NOx needs.
Important Design Considerations
Low NOx Needs
Our proven designs use the very latest low
NOx techniques and standards. Our furnace,
the workhorse of the boiler, is designed for low
volumetric heat release. The lower the release rates,
the “easier” your boiler works. As your boiler works
easier, less stress is put upon the steel, tube ends,
refractory, etc., resulting in a longer lasting boiler. In
addition to longevity, a larger boiler makes for ease in
firing using any selected burner vendor.
Being America’s Boiler Company, we know what
burner vendors are looking for in boiler designs when
it comes to reduced NOx combustion levels—large
furnaces, high heat transfer, and low draft losses:
• Large furnaces mean low volumetric release rates. • High heat transfer for the most efficient boiler for your application.
• Less burner motor horsepower so less energy is used to operate your boiler. Smaller furnaces are extremely susceptible to erratic
flame patterns. Deformed flame patterns cause
uneven heat distribution, uneven absorption and
localized hot spots, which can lead to overheating
and over stressing. Our selections give the customer
the choice of any of the major low NOx burner
manufacturers. Because we have so many proven
product design selections to choose from, we can
custom fit any of our products to your boiler room.
Burnham Commercial can offer you firebox, threepass or four-pass wetback scotch. We are
the only manufacturer who can offer
their packages complete with flue gas
recirculation piping, when necessary. That
eliminates extra design responsibility and
field installation costs.
Proven Product Applications
Unlike any other manufacturer, every Burnham Commercial Low NOx package is design application
approved by our own Engineering Department and
our burner vendors’ Engineering and Applications
Design Groups. Our 140+ years successful track
record assures you that our products, and our vendor
selection, are the best available.

Series 4F
Forced Draft Firebox Boiler

Series 4F Forced Draft Firebox Boiler
The Versatile Boiler
The Burnham Commercial 4F forced draft steel
firebox boiler is a consistent sales leader in the
heating industry. Its compact and constructive
design saves on installation, operation, and maintenance.
4F Saves on Installation
The 4F is a compact boiler that fits where other
designs of similar capacity cannot. Available for
15 psi steam and 30 or 60 psi water*, the 4F
can serve perfectly as the heart of almost any
system. As a factory assembled, forced-draft fired
boiler, this packaged unit does not require a tall,
expensive vent stack or excessive jobsite time and labor.
4F Saves in Operation
•
The furnace surrounds the flame with highly efficient waterbacked primary heat absorbing surfaces. This large
combustion chamber is easy to fire and accommodates many forced-draft
burners without flame impingement or other critical firing problems.
•
Forced draft firing makes the 4F inherently more efficient than boilers using outmoded atmospheric burners and gives you a feature that atmospheric units cannot offer: the option of burning gas or oil.
•
A dual fired burner allows you to burn the more economical fuel or the most readily available fuel at the flip of a switch and affords you leverage in negotiating fuel prices.
•
The 4F is an economical heat source, whether used singly or in multiples. In fact, 4F’s with modulating burners may be sequenced to operate in a step-fired system more cost effectively than a large number of space saver boilers when ongoing maintenance costs are considered.
4F Saves on Maintenance
• Superior design makes the 4F easy to clean and
maintain — requiring no special tools, materials, or skills.
•
Opening the front flue door allows firetubes to be brushed out quickly, unlike the watertubes used in some boilers which can be virtually impossible to clean.
• Elaborate or expensive proprietary seals are not required to re-close the doors as with some boilers.
• As a wetback boiler, there is no delicate or expensive rear refractory to maintain.

C Series Compact Packaged Boiler
America’s Boiler Company
FRONT
REAR
The Burnham Commercial C Series compact packaged
boiler was designed using our 140+ years of boiler
experience and is sold and serviced through the largest
and most experienced network of sales representatives in
the country. With a complete commercial product offering
and unmatched sales and technical support, it’s no wonder
why we are America’s Boiler Company!
Packaged Boilers That Can Actually Fit
Through A Door!
The C Series Firetube boiler is fully packaged and
designed to provide maximum cost and energy efficiency.
The C Series boiler fits through any standard 36” x 80”
doorway, eliminating the need for any costly building
alterations or difficult site assemblies. This convenient size
allows for easier and less expensive retrofit or upgrade of
an existing boiler room.
and extra heavy tube sheets assure the continued airtight
conditions necessary for efficient combustion. Opening the
front flue door allows convenient access to the firetubes. By
brushing out all of the firetubes, the original efficiency of the
boiler is restored in a matter of minutes. All tube ends are
rolled in accordance with the ASME code and are inspected
for hydraulic tightness by an independent insurance
inspector, prior to shipping.
These installation, operation and maintenance features add
up to real savings for you. Factory testing assures you that
the boiler will deliver clean, quiet and reliable heat from the
day it’s installed.
A forced-draft unit, the C Series avoids the expense of a tall
stack and is much more economical to operate and install
than atmospheric-fired boilers. The forced draft creates a
more controlled combustion, and a more thorough mixture
of fuel and air is acheived resulting in optimum efficiency.
Other design features help maintain this durability and
economy over the years. While the original efficiency of
some other boilers can decrease when outer wrappers
develop air leaks and tubes cannot be cleaned thoroughly,
the C Series overcomes these problems. Built to ASME
standards, its outer shell of heavy welded steel boilerplate

Component Summary Information
A boiler is not only a significant plant expenditure, but it is the most important element of any mechanical heating/process
system. The continued reliability of the boiler is heavily dependent upon the quality and chemistry of the water within
the system. Burnham Commercial features a complete line of boiler room accessory products designed to match the
performance needs of your Burnham Commercial boiler. Proper use and installation of this equipment can significantly
improve system efficiency and boiler longevity.
Burnham Deaerator Systems are designed to protect your Burnham boiler and steam
system from the corrosion caused by the presence of non-condensable gases. A solution of
oxygen in water is very corrosive to metals widely used in stem systems. Use of deaerator
systems pay for themselves in fewer downtime hours, less chemical additives and reduced
maintenance to the entire steam system.
Burnham Water Softener Systems are designed to produce conditioned water to reduce the minerals which produce detrimental scale formation on the heat transfer surfaces in the boiler. Use of a
water softener reduces the need for other chemical scale control additives.
Burnham Chemical Feed Systems enable treatment of boiler feedwater with chemicals
that protect against boiler scaling and corrosion. Amount and type of chemical treatment
will vary depending upon the individual application.
Burnham Boiler Feedwater Systems are designed to efficiently store and return hot
condensate in combination with make-up water to automatically meet boiler water demands.
Use of boiler feedwater systems can account for significant fuel savings and lower total
chemical treatment costs.
Burnham Condensate Return Systems are complete systems designed to increase
the energy/water saving circuit for steam heating or process systems and minimize
difficulties from boiler encrustation by recycling previously-treated system water.
Burnham Blow Down Systems are designed to eliminate mineral build-up from
dissolved solids that would cause scale and boiler corrosion. They are available in
two basic types: Bottom Blow Down designed for forceful removal of bottom residue
and Surface Blow Down/Heat Recovery which is an ongoing process that removes
dissolved solids from the top level of water in the boiler while providing a heat recovery
function as well.

• Closed or Pressure Type - A Blowdown Tank subjected to the maximum steam boiler pressure must be
constructed for such pressure and stamped with either New Jersey, National Board or ASME Standard.
• When the blowdown from any steam boiler is disposed in a sewer or other interconnected system, a Blowdown Tank must be placed between the boiler and the sewer or system.
• The minimum metal thickness of Blowdown Tanks, whether pressure or atmospheric, must not be less than 5/16”.
• Atmospheric or Vented Type - The outlet from the Blowdown Tank shall be twice the area of the boiler blowdown pipe and made to extend internally within 6” from the bottom of the tank.
• A vent pipe, at least twice the diameter to the inlet, shall lead to the outside atmosphere. • Vents shall be as direct as possible to the outside of the
atmosphere and discharge at a point not less than seven feet above the adjacent walkway or areas without a valve or other possible obstruction such as a water pocket.

Flash Separator
• Reduces steam pressure or vents process steam directly to atmosphere.
• Eliminates moisture from process steam (cyclonic spinning mechanism permits the use of smaller tanks to completely separate flash steam from condensate).
• ASME Section VIII “UE” stamped separator standard up to model BFS-16-56.
• ASME Section VIII “U” stamped separator standard for models BFS-16-56 and above.
• Sized to accommodate a given #/hour flow rate of steam from a given source psig to a given vent psig.
• Model Range:
6” diameter x 34” high through 36” diameter x 108” high.
• Modular configuration to meet customer requirements includes a flash separator and the following options: trap, check valve, ball valve, safety relief valve and gauge glass.
• Can be custom configured to meet customer requirements.
• Stainless steel striking plate standard.

Follow the “Pressure From...” down vertically on the
chart at left to the “Pressure To...”.
Example:
75 PSIG condensate flashed to low pressure heating system at 15 PSIG gives 7.6% condensate flashed into system.
After determining the percent of flash from the chart above, determine the size of Flash Separator from the chart below.
Example: Referring back to the chart above, you have a 7.6% flash, If you have 30,000 #/hour condensate at 75PSIG, 2,280 #/hour steam (30,000 x .076). Locate 30,000
in the left column below, go across to 2,280 #/hour flash steam column (3,000). You would use a 56” high x 18” diameter Flash Separator with a 3” draft and 5” vent.
