[0002] A coal stove refers to a stove that uses coal as fuel. It is used in the north for heating and cooking in winter. Coal stoves are divided into ordinary coal stoves, coal ball stoves, coal cake stoves and honeycomb coal stoves according to the different coal products used. An ordinary coal stove uses coal blocks as fuel, a coal ball stove uses coal balls made of coal powder, and a coal cake is made of coal in the shape of a cake with small holes on it. The structure of a honeycomb coal stove is slightly different from that of an ordinary coal stove because it uses honeycomb coal. The small door in the front can be opened and closed to keep the coal fire from going out.

[0003] The structure of a coal stove in the related technology includes a furnace shell, inside which are arranged furnace bars, on which coal blocks are placed, and below which are arranged ventilation pipes, for ventilating the coal blocks on the furnace bars when they are burning so as to facilitate combustion of the coal blocks, and on which are arranged furnace feet on the side of the furnace shell close to the ground, through which the furnace shell is placed on the ground, and on which are arranged a smoke exhaust pipe, one end of which is arranged outside the furnace shell, and the other end of which is arranged inside the furnace shell, for exhausting smoke generated when the coal blocks are burning.

[0004] When using a coal stove, a large amount of heat is generated, which will cause the smoke exhaust pipe to generate high heat, resulting in energy waste. In addition, during the use of the coal stove, the exhaust gas contains pollutants such as suspended particles, sulfur dioxide and nitrogen dioxide, which will cause serious air pollution when discharged into the air.

A water pump 33 is arranged on the treatment pipe 32. The water pump 33 transports the water in the water tank 31 to the smoke exhaust chimney 2 through the treatment pipe 32, and then sprays the water on the absorbent 34, so that the absorbent 34 becomes wet to enhance the adsorption capacity of the absorbent 34. After the smoke generated by coal combustion enters the smoke exhaust chimney 2, it enters the absorbent 34, and the carbon monoxide, carbon dioxide, sulfur dioxide, nitric oxide, nitrogen dioxide and inhalable particulate matter in the smoke are adsorbed by the absorbent 34, thereby treating the harmful substances in the smoke.
