what is the cause of gas on coal-fired boilers

1t coal-fired boiler emission flue gas

Mercury emissions and partitioning from Indian coal-fired Airflow and flue gas flow is slightly lower or about the same. Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion. Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air).

Coal-Fired Boiler - an overview | ScienceDirect Topics

Conventional PF coal-fired boilers currently being used in the power industry use air for combustion in which the nitrogen from the air (approximately 79% vol) dilutes combustion products such as CO 2 and water vapor in the flue gas. During oxyfuel combustion a combination of oxygen (typically of greater than 95% purity) and recycled flue gas is used for combustion of the fuel.

Coal Fired Boiler Emissions Test - EPA

Jun 15 1994 · Entropy tested the exhaust gases from the Unit 1 coal-fired boiler. The furnace burns bituminous coal. Gases from the combustion furnace pass through two electrostatic precipitators (ESPs) to control particulate. Gases exiting the ESPs pass through a flue gas desulfurization unit (FGD) to remove SO2 and are then exhausted through a stack.
