The above mentioned three m odes of dust removal can all satisfy the requirement of Indian coal fired boiler flue gas cleaning if selected properly. For electrostatic precipitators, due to specific charac- teristic of Indian coal and ash, size of ESP must be sufficiently …

compliance in two phases for coal-fired boilers rated at 25 MW e or more. Phase I, applying to 110 boilers that are among the largest utility sources, required emission lev-els of no greater than 1075 ng SO2/J (2.5 lb/10 6 Btu) by January 1, 1995, with provision for a two-year extension for implementing ≥ 90% removal technologies under most

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.
