The grate surface of the chain-type grate is actually the chain belt itself, which is driven by sprockets to move the grate bars slowly forward. Typically made from cast iron, the grate bars are assembled with essential ventilation gaps maintained between each bar. Additionally, adjustable air-control chambers are often installed beneath the grate, allowing precise regulation of airflow through these gaps into the fuel layer for combustion. Coal is evenly fed onto the grate from a coal hopper located at the front end, and the thickness of the coal layer can be adjusted by raising or lowering a coal gate. As the grate moves backward, the coal gradually ignites, burns, and eventually burns completely. The resulting ash and slag are then removed manually or mechanically. In some systems, instead of using a hopper to feed coal, a coal-spreading machine is employed to fling coal onto the rear portion of the moving grate, which propels the grate forward. The speed of the grate is regulated by a gear-driven variable-speed mechanism, tailored specifically to the type of coal and the boiler's operational load.
