Fuel preparation for a pc boiler occurs in a mill, where coal is typically reduced to 70% through a 200-mesh (74-μm) screen. Figure 2 shows a particle-size distribution from a bowl-mill grinder typically used in power plants. A typical utility specification for particle size distribution of the coal is that 70% of the mass should pass through a 200-mesh screen, which is equivalent to 70% …
Enhanced Combustion Efficiency: FBC boilers mix fuel and air more effectively than conventional boilers, resulting in higher thermal efficiency and improved energy output. Reduced Emissions: FBC boilers produce lower emissions of nitrogen oxides (NOx), sulfur dioxide (SO2), and particulate matter.This is beneficial for air quality and compliance with environmental regulations.
The FBC boilers are designed with under bed feeding system / over bed feeding system or with both the systems depending upon the fuel combinations & flexibility desired. In the case of multi fuels, it is possible to have metering of all fuels. Or only the main fuel can be metered and
Valmet has been developed circulating fluidized bed (CFB) boilers for over 30 years, and has delivered dozens of biomass or biomass co-firing projects during the last 25 years. In the 1980s CFBs were only coal firing equipment. Today they are multifuel firing equipment, and sometimes even biomass boilers. Boiler conceptual designs and ...
