High-efficiency coal-fired furnace

Abstract

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.

Description

technical field [0001] The invention belongs to the field of heating and heating equipment, and in particular relates to a high-efficiency coal-fired furnace. Background technique [0002] Coal-fired stoves have a very broad market in rural areas of our country. People use them for cooking, boiling water, and heating, and they are one of the necessary living appliances. Limited by the structure of the coal-fired furnace body, the added coal often cannot be fully burned, resulting in a large amount of black smoke, which has caused serious pollution to the environment. However, existing improvements to coal-fired furnaces generally focus on increasing the amount of coal fired Within the scope of the auxiliary facilities around the coal furnace, such improvements will not help to improve the fundamental defect of insufficient combustion of the coal furnace. Contents of the invention [0003] In view of the problems existing in the above-mentioned coal-fired furnace, the pres...
