Description

Coal firing stove with vaporization burner

The utility model relates to a kind of honeycomb briquette stove with the coal gas vapourizing unit.

The report of many multifunction burning coal stoves is arranged in the patent documentation in recent years, but all do not properly settle the problem of gas purification and second-time burning.Chinese patent CN86206775 and CN2039801 be disclosed coal stove respectively, the two all be with coal-fired gas discharge fume be applied to after handling aerial, Chinese patent CN1059024 discloses a kind of steam coal stove for household, it has increased closure and has removed devices such as coal ash structure and steam particle burning device, processing to coal-fired gas is that the way of taking Scavenger fan is installed in stove case central authorities solves, cause complex structure and cost up, coal gas does not purify yet and is discharged into aerial.

The purpose of this utility model is that the steam that will utilize waste heat to produce carries out desulfurization and vaporization process to coal-fired gas, participates in second-time burning then, reaches the effectiveness that improves utilization rate of coal and protection environment.

The utility model is achieved in that

In closed stove case shell, a median septum is arranged, median septum top combuster, fuel chamber, coal gas vaporization and burner, steam raising plant, boiler, steam box etc., the median septum below has temperature to hide case, slag-draining device etc.

The coal gas that produces during the coal cinder burning gathers fuel chamber, under coal gas compression cover and air effect, coal gas enters coal gas storage pipe slowly along appendix, the water vapour that produces from boiler is risen by steam pipe and is risen to coal gas storage pipe, ducted coal gas is carried out desulfurization and vaporization process, make it to be decomposed into fuel gas, sediment and other gas, fuel gas carries out second-time burning with steam from the flame that the jet channel of spray orifice through the pot seat is sprayed onto coal gas compression cover top then.The steam that is positioned at the steam generation ring generation of stockhole enters steam box through steam transmitting pipe, can cook food.The heat that utilizes combustion chamber and steam box to distribute, but temperature is hidden the case heat preservation food, the slag tooth that stirs of bottom, combustion chamber is fixed on the axostylus axostyle, when it is static, plays a part grate, the supporting coal cinder, and during rotation, gear can blend coal cinder, and cinder is shaken off in the drawer type ash bucket.Tapping process is enclosed, the favorable environment health.

Below in conjunction with accompanying drawing, further set forth structure of the present utility model and embodiment.
