Coal-Fired Boiler - an overview | ScienceDirect Topics

H. Widell, in Biomass Combustion Science, Technology and Engineering, 2013 Furnace design. Just as coal-fired boilers are not designed in the same way as oil- or gas-fired boilers, neither can biomass-fired boilers be designed as coal-fired boilers, if they are to function efficiently. Biomass firing requires a larger furnace (i.e. a larger radiation heat transfer surface) than coal firing.
