Heat source room is made up of some combustion chambers side by side, and in order to thermal source to be provided, the combustion chamber is a drawer type, each combustion chamber is formed by openable fire door, stove tube and bottom ash bucket, the stove tube can have the coal tube of being made by refractory material by extracting out in the combustion chamber in the stove tube, in order to hold the honeycomb briquette burning.Ash bucket is a drawer type, and each combustion chamber can be provided with separately, also can an ash bucket be set the unification of several combustion chambers.

The heat source room top is a front smoke chamber, and it is a sealing chamber, the burner of each combustion chamber and the entrance point of the heat exchanger tube on the sidewall in order to capping, leaks to prevent flue gas.

Some heat exchanger tubes are installed in the Heat Room side by side, and heat exchanger tube is a S shape heat exchanger tube, and which is provided with fin, can improve the heat exchange effect like this, and the entrance point of heat exchanger tube is communicated with front smoke chamber, and its port of export is communicated with rear smoke chamber.

Rear smoke chamber is a rectangular cavities, and its top is provided with smoke exhaust pipe, and flue gas is discharged giving up.

The Heat Room below is a plenum chamber, is installing blower fan in it, and the blower fan exhaust outlet leads to Heat Room.

The Heat Room top is installed with the air supply duct towards the room on the body of heater, import department is installed with evaporation coil in the air supply duct, and it is linked to each other with the condenser of peripheral hardware by tube connector.

Application process of the present utility model is that honeycomb briquette burning produces in each combustion chamber heat energy and hot flue gas compile front smoke chamber and enter heat exchanger tube, air in the heat exchanger tube heating Heat Room, and the air-flow that blower fan is discharged is sent into the room heating with hot-air through air supply duct continuously.

Behind the burning certain hour, open fire door, the stove tube is extracted out, the coal tube is therefrom proposed, fill out coal, deashing or operation such as bank up a fire to outdoor, then the coal tube is put into the stove tube, push back the combustion chamber, the pass upper furnace door carries out next step combustion process.Can effectively avoid airborne dust like this, help sanitation and hygiene in the holding chamber.

Hot season in summer, stop using in the combustion chamber, starts condenser, makes the evaporation coil refrigeration in the air supply duct, air in the cooling pipe, and fan airflow is sent into the room air conditioner refrigeration with cold air through air supply duct.

The utility model can be used as the room ventilation ventilator and uses if only start blower fan, to regulate room air.

The utility model can be banked up a fire to each combustion chamber by fire sealing cover as the normal cellular coal stove, with the combustion process that slows down in the heating process, reduce heating load, when need strengthen heating load, draw back the below ash bucket a little, increase intake, the accelerated combustion process.

The utility model is if transform coal barrel structure in the combustion chamber a little, and also incendivity coal briquette or coal cinder have identical effect.

The utility model is compared with existing coal heating stove, has following advantage:

1, owing to adopt air to make heating agent, can significantly reduce water consumption, the conserve water resource, and also air-flow can promote the room air circulation, with fresh air in the holding chamber, be of value to health.

2, owing to adopt enclosed burning, the outdoor coal purge mode that changes can significantly reduce indoor airborne dust, helps sanitation and hygiene in the holding chamber.

3, a stove is dual-purpose, and air supply duct installs than water pipe and radiator simple installation, and expense is low, helps applying.
