    FBC boilers: Introduction, Mechanism of fluidised bed combustion, Advantages, Types suspended in the air stream – the bed is called “fluidised”. The fluidised bed combustion (FBC) takes place at about 840°C to 950°C. In AFBC, coal is crushed to a size of 1 – 10 mm depending on the rank of coal, type of fuel feed.

    Here the coal is crushed and injected into swirling air in a cyclone. Burners for coal, oil, or gas are similar in that fuel is injected into the furnace through the center of the burner while air for combustion is supplied through an annulus. The fuel ignites in Once ignited, combustion is slow and occurs at lower temperatures.
