Study on combustion chambers in BlGCC, the loss of energy are discussed by exergy analysis and gases with variable specific heat, based on the essential conception of combined cycle and energy cascade utilization. The result shows: The exergy efficiency is related with not only exit gas temperature of Combustion Chambers but also fuels components and calorific value. The exergy efficiency of combustion chamber increases with improving adiabatic combustion temperature. Comparing exergy efficiency of biomass gas with two different kinds of coal gas at 1147℃: the highest exergy efficiency is biomass gas, the lowest is two different kinds of coal gas. Reforming irreversibility of combustion and heat transmission in different conditions is an important way to improve integrated cycle efficiency. Thus the important results obtained may provide theory basis for further optimizing the system.
