Progress of circulating fluidized bed combustion ...

NO x emission from a CFB boiler is lower than PC boilers due to its lower combustion temperature. The NO x emission from a CFB boiler is less than 200 mg/m 3 and the sulfur retention efficiency by limestone injection into the furnace reaches 9095% [49 50]. The pollutant emissions can meet the emission standards of most countries in the world such as Australia Japan Canada Switzerland Indonesia and

Combustion of Fuels - Carbon Dioxide Emission

To calculate the Carbon Dioxide - CO 2 - emission from a fuel the carbon content of the fuel must be multiplied with the ratio of molecular weight of CO 2 (44) to the molecular weight of Carbon (12) -> 44 / 12 = 3.7. Carbon Dioxide emission from burning a fuel can be calculated as. q CO2 = c f / h f M CO2 /M m [1]. where. q CO2 = specific CO 2 emission [kg CO2 /kWh]
