current and projected coal-fired capacity by APC configuration. 5 BEHAVIOR OF MERCURY IN COAL-FIRED ELECTRIC UTILITY BOILERS Mercury may be present in the flue gas in several forms. The specific chemical form – known as the speciation – has a strong impact on the capture of mercury by boiler air pollution control (APC) equipment.Learn More
There are hundreds of commercially installed SNCR systems on a wide range of boiler configurations including: dry bottom wall fired and tangentially fired units, wet bottom units, stokers, and fluidized bed units. These units fire a variety of fuels such as coal, oil, gas, biomass, and waste. Other applicationsLearn More
The graph below illustrates a typical relationship between flyash LOI and coal fineness on a tangentially fired boiler firing Eastern Bituminous coal. Change in flyash LOI is less dramatic on Western coals due to the coal's reactivity and ash content but this relationship still holds true.Learn More
