  • Can we use biomass fuel in coal-fired boilers?

    Biomass boilers are different from coal-fired boilers. The grate gaps of coal-fired boilers are too large for wood pellets. In biomass boilers, the wood pellets are gasified and fed by a hopper at a constant speed so that they can burn sufficiently. After gasification, the hearth is filled with high-heat flames with little smoke.Get Price
