C + O 2 = CO 2 + 406 [MJ/ kmol ] Hydrogen in fuel reacts with oxygen in the air blast, producing steam H 2 + ½ O 2 = H 2 O + 242 [MJ/ kmol ] Reduction: Boudouard reaction CO 2 + C = 2CO - 172.6 [MJ/kmol] Water-gas reaction C + H 2 O = CO + H 2 - 131.4 [MJ/kmol] Water shift reaction CO 2 + H 2 = CO + H 2 O + 41.2 [MJ/kmol] Methane production reaction C + 2H 2 = CH 4 + 75 [MJ/kmol]Producer Gas Constituents:: Producer Gas Constituents:Slide 9: GAS CLEANING: (1) Tar Bulky and expensive tar separating equipment Reformation at a higher temperature zone (2) Dust: ▼ Design of equipment Load to the gasifier Type of fuel Cloth filters Electrostatic filters GAS COOLING Natural convection coolers Forced convection coolers Water coolers Scrubbers Heat exchangersOperational difference between diesel and gasoline engine: Operational difference between diesel and gasoline engineSlide 11: Producer Gas Drive Diesel EngineConversion of diesel engine to producer gas : Conversion of diesel engine to producer gas Diesel engines are compression ignition engines with compression ratio of 16-24 Fuel is ignited by high gas air temperature operated on dual fuel or converted completely into spark ignition engineConversion of gasoline engine to producer gas: Conversion of gasoline engine to producer gasPower Recovery: Power RecoverySlide 15: Turbo charging Delivers the gas-air mixture at a differential pressure of 1atm ▼ Achieves a increase of compression ratio from 5 to 10 Increased Compression Ratio Recovers Power loss CR as high as 10 – Technically and Economically feasibleDual Fuelling : Dual Fuelling Small amounts of gasoline with gas-air mixture Starting the engine on gasoline and then switching over to producer gas drive Dual fuelling when additional power is neededProducer Gas Hazards:: Producer Gas Hazards:Slide 18: FIRE HAZARDS REMEDIES Insulation of hot parts of systemSlide 19: EXPLOSION HAZARDS CAUSES Air leakage into the gas system Air penetration during refueling REMEDIES Ventilation of the system before igniting the fuelToxic Hazards:: Toxic Hazards:Slide 21: Application Requirements Rural Electrification Short duration, 4-6 hrs /day Load reasonably constant Industrial-Captive Continuous operation, 24hrs x 6/7 days a week Large load fluctuations Independent power producer –grid lined Continuous operation, 24hrs x 7 days a week Large load fluctuationsConclusion: Conclusion Smooth operation is possible right from the highest CR of 15-20 This study therefore paves path for the possibility of adapting commercially available gas engine for large scale power generation application, albeit loss of power to an extent of 15-25%. This loss in power is compensated to a much larger proportion as these technologies generate fewer amounts of toxic gases (low NOx and almost zero SOx) and zero towards Green House Gas emissions.THANK YOU: THANK YOU SKY You do not have the permission to view this presentation.
