2019/1/1 · Key PM control technologies for ultra-low emissions coal-fired power plants. Typically, the overall PM removal efficiency of DESP or FF can be up to 99%+. However, the removal efficiency for fine particles, especially for particles with diameters of 0.1–1 μm, is lower than 90% by using traditional DESPs and FFs [11].

Capsule Report: Particulate Control by Fabric Filtration on Coal Fired Industrial Boilers - United States Environmental Protection Agency

However, recent events—namely,, the conversion of oil- and gas-rired boilers to coal and the pending promulgation of more stringent particulate emission reguletions—have led to a renewed interest in the use of baghouses for boiler particulate control. Currently about 40 industrial coal-fired boilers are controlled by fabric filtration systems.

The advantage is that the low-emission swirl burner for biomass co-firing with coal in the power boiler secures biomass dust co-firing with coal dust in large power boilers. Biomass dust is fed to the burner through a separate nozzle placed in the axis of the burner and mixes with the pulverized coal outside the burner already in the combustion zone of a power boiler.
