POLLUTION – Global Issue Pollution and Environmental Damage - Nitrogen - Sulphur Dioxide - Poor air quality & Smog - Acid rain Smog - Forest damage - Depletion of Ozone layer - GREENHOUSE EFFECT NOx SOx POLLUTANTS CARBON DIOXIDE Produced by combustion of fossil fuel/coal/oil/gas C + O2 = CO2 ….carbon fuel CH4 + 2O2 = CO2 + 2H2O …..gas fuel CO2 absorbs infrared/heat radiation/sun Melts polar ice caps Smog Stoichiometric burner parameters - flue gas O2 least / CO2 max - efficient burners low excess air / least CO2 POLLUTANTS OXIDES SULPHUR Burning of fuel sulphur S + O2 = SO2 ….further oxidation 2SO2 + O2 = 2SO3 ….moisture in air SO3 + H2O = H2SO PRIMARY AIR POLLUTANT SECONDARY AIR POLLUTANT POLLUTANTS CARBON MONOXIDE - Lack of oxygen during combustion - Flame is chilled - Fatal Gas T Series Air Staging POLLUTANTS NITROGEN OXIDES NOx - high 0 C of combustion process - in precombustion/combustion and post flame region - combustion air Nitrogen and natural and organic Nitrogen in fuel NO + NO2 POLLUTANTS SMOKE - Excess fuel - Incomplete combustion - flame impingement - Smoke .. Carbom particles….into Air - Fouling of boiler surface - reduce efficiency POLLUTANTS NOISE - Damaged hearing & Stress related - Unwanted sound - Disrupt working efficiency !! SOLUTIONS NOx Reduction - Furnace capacity MW/m3 - Temp of Furnace wall - Furnace dimension ratio 3.5:1 - Preheated Air & Humidity SOLUTIONS - External flue gas circulation - Air & fuel Staging ……Dunphy’s - Water & steam injection SOLUTIONS BURNER DESIGNS - Gun Type - Rotary cup - Co-axial ….fulfills all req of combustion ….controlled & uniform air ….higher efficiency lower pollution ….quiet & low noise levels SOLUTIONS ZENITH THERMAL EQUIPMENT P LTD, HYDERABAD BOILERS HEATERS WELCOME TO ZENITH THERMAL EQUIPMENT ENGINEERING EXCELLENCE Zenith Thermal Equipment Office: Stone-Acre, 8-2-618/B, Road No 11, Banjara Hills, Hyderabad 500 034, AP, India Works: 99 AA, Thimmapur, Station Road, Kothur, Mehboobnagar, Andhra Pradesh, India www.zeniththermal.com / info@zeniththermal.com Tel: 91-40-3326111 Fax: 91-40-3398681 Turn your speakers on and press enter OK Zenith Thermal Equipment Expertise, Experience & Engineering Excellence Manufacturing since 1982 ENERGY efficient & ECO friendly Low NOx Boilers Thermal Fluid Heaters Chemical Plant / Economizers / Incinerators OK Zenith Thermal Equipment Designs & Technical Support from Babcock Robey UK Apparatebau Wiestock Germany Dunphy Combustions Ltd UK OK Zenith Thermal Equipment Zenith Boilers Design & Benefits single/twin furnance - 500 – 27000 kgs/hr & higher conventional 3 pass wet back - class 1 IBR 1950 custom built / dual fuel / robust / time proven min fuel – steam demand - high efficiency continuity & reliability – steam production low running cost / maintenance / emmission OK Zenith Thermal Equipment Zenith Boilers Design & Benefits Low heat transfer – heating surface High output – no overstressing High steam volume – large shell disc High quality dry steam – varying load High integrity welded construction Low NOx emission design OK Zenith Thermal Equipment Zenith Boilers Design & Benefits High specification feed pumps Level controls / water sampler Choice of burners 3 Access points + Front Access – easy maintenance High density insulation / mountings OK Zenith Thermal Equipment Burners & Combustion Technology Precision machined LM6 Al & Individually matched High quality BS EN ISO 9001 coaxial burners Low emission / Low noise & vibration Energy efficient Air distribution / Air damper Dual facility / mixing performance / Ratiotronic High Safety – operations control OK Zenith Thermal Equipment Services Energy solutions & consultancy Turnkey manufacture & supply – custom built Commissioning & installation – site work Operator training, safety & service Maintenance & service – on site / on call Spare parts – comprehensive parts stocks OK Zenith Thermal Equipment Other Products Thermal Fluid Heaters 50000KCal/hr – 5000000Kcal/hr Reactor Vessels 30 HP / 20 KL capacity Storage Tanks / Heat Exchangers / Hot Air Generators Burning Ovens / Precipitators / Absorption Tower SS Cyclone / Economizers / Incinerators / etc OK Zenith Thermal Equipment Clients: Orchid Pharmaceuticals, Chennai Orchid Healthcare, Chennai Ministry of Gas USSR Raymonds Woolen Mills, Mumbai / JK Industries IFB Agro Industries, Kolkata ITC Bhadrachalam Kohinoor Silk Mills, Surat Starchem, Hyderabad Mangalore Breweries & Distilleries SM Dyechem Ltd, Pune OK Zenith Thermal Equipment OK Zenith Thermal Equipment DISCUSSION BOILER TECHNICAL SPECIFICATION BURNER MANAGEMENT SYSTEM EFFICIENCY LOW EMISSION COST BENEFIT top quality top quality awesome www.zeniththermal.com
