Operation principle of the present invention,

Honeycomb briquette is placed on into burning in thorax cylinder 9, by adjusting the size of air inlet 6 burning time of honeycomb briquette can be controlled And ignition temperature, the carbon monoxide and carbon dioxide of honeycomb briquette burning generation are up discharged on table 16.

Coal stove is to place container on table 16 or reduce the oxygen-supplying amount of honeycomb briquette when producing carbon monoxide highest When, the attaching space of table and air is covered when being placed on table 16 due to container, the carbon monoxide for causing honeycomb briquette to produce Effectively and timely cannot react away with oxygen combustion, carbon monoxide and oxygen reaction temperature to be not less than 650 degree, therefore, when one Carbonoxide is left after table 16, and temperature is reduced cannot be with oxygen reaction；The air-breathing groove 7 at the edge of table 16 sucks air from bottom Afterwards, Jing fin heating after, the high-temperature hot air of discharge is poured in table 16, and formed in swirling air-flow, with table one Carbon oxide gas are fully contacted reaction, and burning is complete, and carbon dioxide sinks from steam vent 8 to sinking to discharging.

Because the upper end space of table 16 can endlessly be provided high-temperature hot air, therefore the oxygen that honeycomb briquette is produced Changing carbon can rapidly be burned completely.

The air quantity delivered of honeycomb briquette is mainly controlled by air inlet 6 and bell 15, and the air supply above table Amount is mainly controlled by air-breathing groove 7, therefore the burning time of honeycomb briquette still can be brought under control.

Because hot-air can rise automatically, therefore blower fan can be set in the bottom of air-breathing groove 7, can also form nature Hot-air suction, arrange after blower fan can convenient regulation suction air amount, using can be convenient.

The thermostable heat-conductive material that thorax cylinder is adopted can be refractory brick, metal such as copper etc..
