Coal Fired Boiler Emissions Test - EPA. 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. exiting the ESPs pass through a desulfurization unit (FGD) to remove SO2 and are then exhausted through a stack.
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.
The effects of flue gas recirculation ratio, air preheating temperature, oxygen concentration, and fuel types on pollutants emission in the volumetric combustion system were investigated. According to the results, it was con- cluded the higher substitution ratio of biomass in a co-firing boiler, the lower emissions of NOx and SOx.

Typically, coal with low sulfur level tends to produce fly ash with high resistivity. The ESP cannot build up an electric field that is strong enough to collect high resistivity particles, leading to higher than usual emissions or a break through of the ESP at high load.
