Multiphase Reactor Engineering for Clean and Low-Carbon

Furthermore, biomass fuels increase fouling and agglomeration of the bed material in CFB boilers, which will require maintenance and boiler shut-down [44, 48]. Fouling is a problem for grates as well, but can be prevented by cooling of the grate to a point below the melting point of ashes, which will make these drop off from the grate.

plant. Biomass-cofired coal plants can achieve slightly lower heat rates, as exemplified by Greenidge Station (11,000 Btu/kWh on the biomass portion of the fuel, compared to 9818 on coal alone). The least efficient plants in this report have heat rates of about 20,000 Btu/kWh. A "typical" value is about 14,000 Btu/kWh (24.4% thermal efficiency, HHV).
