COAL ADDITIVES
COAL ADDITIVES
ARE THEY ECONOMICAL?
Cost of Treatment =~5 % of Coal Cost
Benefits Due to Improvement in Combustion
Efficiency, Increase in Time Between Cleanings,
Reduction in Maintenance Cost and Coal Flexibility =
> 10 % of Coal Cost
Hence, it Makes Sense to Treat the Coal
COAL ADDITIVES
TCHNOLOGY
AMTEK Coal Additive Technology is Based on 60 Years
of US and French Patents by its Partners.
TYPES OF COAL
BITUMINOUS
(High Calcium,High Carbon)
LIGNITE
(High Moisture, High Volatiles)
PET-COKE
(High Sulfur)
BOILER TYPES
COAL SIZE
FIXED GRATE TYPE BOILERS - 25~50 mm size Coal
STOKER TYPE BOILERS - 10~15 mm size Coal
FLUIDIZED BED BOILERS - 6~8 mm size Coal
PULVERIZED COAL BOILERS - 200 MESH = 0.075
mm Coal
PROBLEMS IN COAL COMBUSTION
SMOKE, NOx & SOx EMISSION, ACID RAIN
CLINKER ON FURNACE BED [Agglomeration]
FIRE TUBE DEPOSITS
SLAGGING ON WATER WALLS & SUPERHEATER
FOULING ON BACK END
CORROSION ON BACK END

COAL ADDITIVE
POWDER
POWDER COAL ADDITIVE -AX 7020 is sprayed
over coal before grinding or pulverization or feeding.
VERY EASY TO USE.
COAL ADDITIVE
WHAT DOES IT DO?
CATALYSTS CATALYZE COMBUSTION OF COAL
PARTICULATES UP TO 350 ℃ IN FIRE ZONE
AGAINST >650 ℃. This reduces UBC.
DEPOSIT AND CLINKER INHIBITORS REACT
WITH DEPOSITS & CLINKER AND MAKE THEM
FLUFFY, NON ADHERENT AND EASILY
REMOVABLE BY FLUE,MANUALLY OR SOOT
BLOWERS.
AMTEK LIQUID IN FIRE
ADDITIVS
LIQUID IN FIRE ADDITIVE AX 2750 IS
CONTINUOUSLY INJECTED INTO FURNACE TO
REDUCE UBC.
LIQUID IN FIRE ADDITIVE AX 2760 IS SPRAYED INTO
FURNACE TO INHIBIT DEPOSIT FORMATION AND
MAKE THEM EASILY REMOVABLE.
LIQUID IN FIRE ADDITIVE AX 2770 IS SPRAYED INTO
FURNACE TO REDUCE UBC & DEPOSITS
WHAT IS --- AMTEK ONLINE CHEMICAL
TREATMENT (AOCT)
IN AMTEK ONLINE CHEMICAL TREATMENT,
SUITABLE CHEMICAL IS CONTINUOUSLY OR
INTERMITTENTLY INJECTED AT MULTIPLE POINTS
IN THE FURNACE.
THE CHEMICAL IS STORED IN A TANK.IT IS
PUMPED THROUGH FLUID LINES AND
CONTROLLED BY VALVES. IT IS INJECTED INTO
THE FURNACE WITH THE HELP OF INJECTORS.
SOOT REMOVERS
AMTEK RESEARCH Offers Soot Remover Packs
AX 7010 for Direct Injection Into Furnace to Burn
the Soot Adhering on the Fireside.
AX 7010 is Injected Into Furnace Through Peep Holes
Once Every 4~8 Hours.
