    May 02, 2018· In Travelling Grate boiler coal is fed at one end of a moving steel chain grate. As grate moves along the length of the boiler furnace, the coal burns before dropping off at the end as ash. Some degree of skill is required, particularly when setting up the grate, air dampers and baffles, to ensure clean combustion leaving minimum of unburnt carbon in the ash.

    Guide To Clean And Efficient Operation Of Coal-Stoker

    The most accurate way of determining boiler efficiency in stoker-boilers is to use what is known as the heat loss method. (Ref #16) In this method you simply measure the individual heat losses (expressed as percent of heat input) and subtract them from 100%. This is possible because energy is conserved.

    Jan 01, 1982· Systematic experiments on both chain-grate 13 and coking stokers 12 have shown that boiler efficiency can fall 0.2–0.4% per 10% increase in material below 3 mm with a low-ash coal and up to three times this for an untreated coal. No equivalent reduction in efficiency with increasing ash occurs in fluidized-bed combustion units.

    1.2 Anthracite Coal Combustion

    A second type of stoker boiler used to burn anthracite coal is the underfeed stoker. Various types of underfeed stokers are used in industrial boiler applications but the most common for anthracite coal firing is the single-retort side-dump stoker with stationary grates. In this unit, coal is fed intermittently to the fuel bed by a ram.
