The invention aims to provide an efficient
coal furnace. Grates comprise a fixed grate and a rotating grate; a fixed plate is fixed in a
hearth, the fixed grate is fixed between the fixed plate and a furnace body, the furnace body is further sleeved with a rotating shaft, one side of the rotating grate is fixedly connected onto the rotating shaft, and a support plate for supporting the rotating grate is further arranged on the furnace body corresponding to the other side, opposite to the one side, of the rotating grate; the fixed plate and the rotating shaft are adjacent and located in the middle of the lower part of the
hearth. When the efficient
coal furnace is used,
coke is added to the fixed grate firstly and burnt sufficiently, then
coal is added to the rotating grate, the rotating grate can be rotated in a coal burning process to pour part of the coal on the rotating grate onto the sufficiently burnt
coke, so that coal burning is accelerated, gaps of the coal can be increased through the action, the sufficient burning rate of the coal is increased integrally, and environmental
pollution caused by
soot emission is reduced.
