Stoker Fired Boiler types of stokers - Boilersin

Travelling Grate or chain grate Stoker Boiler 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,
