Description

Coal gas sectional combustion stove

Technical field

The utility model relates to a kind of combustion furnace, more particularly relates to a kind of coal gas sectional combustion stove, belongs to the improvement of combustion furnace.

Background technology

At present, the combustion furnace used of heat supply generally has coal furnace, oil burner and gas-fired stove etc.Coal furnace is warmed oneself by the production of people's extensive use, particularly winter, life owing to adopt this cheap fuel of coal.It is all economical than burn crude, product oil, natural gas etc., and cost is low again, and the coal resources in China reserves are abundant more than oil.But, coal furnace is owing to directly use the coal combustion heat supply, can produce a large amount of poisonous and hazardous flue gases and dust, cause pollution to atmosphere and surrounding enviroment, particularly seem even more serious in the lower pollution in winter of air pressure, simultaneously, directly low with its thermal efficiency of coal burning heat supply, maximum has only 72%, has wasted coal resources greatly.Also have now and adopt the coal gas sectional combustion to carry out heat supply, number of patent application is that 02273244.6 combustion furnace adopts this structure exactly.But this combustion furnace is insufficient at coal seam skewness when vaporizer carries out stoker feed, aerogenesis; Simultaneously, the coke that the vaporizer of gas port that vaporizer top communicates with the combustion chamber and fire grate top communicates with the combustion chamber transmits mouthful its size and all can't regulated at will control, and has brought inconvenience for the adjusting control of furnace body temperature; Also have, the not enough gas-fired of combustion chamber air feed insufficient, the thermal efficiency is low; And wind chamber sealing is not tight, easily produces tempering in air compartment, has brought steady trouble for the safe operation of combustion furnace.

Summary of the invention

The purpose of this utility model provides a kind of coal gas sectional combustion stove, the size that it not only can regulate gas port and coke transmission mouth easily is used for regulating furnace temperature, and do not produce tempering, thermal efficiency height, safe, pollution-free in the combustion chamber air feed abundance, air compartment.

The purpose of this utility model is to realize like this, it includes vaporizer, combustion chamber, air compartment and slag storehouse, it is characterized in that: a side of vaporizer has fire door, gas port between vaporizer and combustion chamber is provided with baffle plate, the gas port of one side is provided with secondary air channel in the combustion chamber, above the transmission of the coke between vaporizer and combustion chamber mouth, a flashboard is arranged, the tank of sealing usefulness is housed in the air compartment of fire grate below, also be provided with automatic sprinkler in the air compartment.

The utility model has the advantages that, because a side of vaporizer has fire door, small-sized like this combustion furnace just can directly make coal seam cloth coal even by fire door hand-stoked in vaporizer, and large-scale combustion furnace is after finishing stoker feed by the coal feed point at top, also can be easily by the flat coal of fire door, make the coal seam in the vaporizer still can keep evenly having improved coal-fired gas production greatly; Because gas exit is provided with the coal gas baffle plate, the coal gas amount that enters the combustion chamber can be controlled again, furnace temperature can be further controlled; Simultaneously, on the coke transmission mouth that the vaporizer above the fire grate communicates with the combustion chamber, a coal flashboard moving up and down is arranged, be used for controlling the fire coal that enters in the combustion chamber, can be used to control furnace temperature equally; Gas port in combustion chamber side is provided with secondary to airduct, can make the gas-fired that enters in the combustion chamber more abundant; Also, prevented that tempering makes combustion furnace safer in the air compartment because the tank and the seal diaphragm of sealing usefulness are arranged in the air compartment below fire grate; Water injector by automatic temperature measurement device control also is installed in the air compartment, is used for controlling the gas production that furnace temperature in the vaporizer improves vaporizer, have simple in structure, easy to operate, the thermal efficiency is high, free of contamination characteristics.
