Abstract
The utility model relates to a gas stove, in particular to a downdraft straw gas stove, which solves the defect of the existing straw gas stove that the combustion is poor because the structure is unreasonable. The downdraft straw gas stove comprises a stove body. The stove body comprises a hearth with a feed inlet. A vertical air passage and a gas passage are arranged between the inner wall of the stove body and the hearth. An air inlet communicated with the air passage and the ambient air is arranged on the stove body. A gas inlet communicated with the gas passage is arranged on the inner wall of the hearth. A combustion chamber is arranged above the hearth. An air communication zone communicated with the air passage and a gas communication zone communicated with the gas passage are arranged on the inner wall of the combustion chamber. Since the internal structure of the stove body is ingeniously improved, the utility model has the advantages that the combustion in the stove is full, the utilization ratio of the heat energy is improved, the pollution emission is reduced, the processing is simple, the cost is low and the like.
Description
Technical field
The utility model relates to gas furnace, is specially a kind of downdraft straw fuel gas stove.
Background technology
In recent years, in order to solve crop straw burning and to improve the rural energy structure problem, various biomass gas stoves have appearred, the straw fuel gas stove is a kind of of the most normal use, mainly be to allow the interior stalk of burner hearth under the condition of anoxic, burn, generation is based on the flammable combustion gas of carbon monoxide, the straw fuel gas furnace bottom is by the nozzle-type oxygen supply, the mode oxygen supply of oxygen supply of stone or metal plate for standing a stove on as a precaution against fire macropore or annular air intake, flammable combustion gas is combined with air burns, but because that the unreasonable structure of straw fuel gas stove produces firepower when causing burning is not enough, it is insufficient to burn, defective such as extinguish easily, give the daily heating of people, cook and cause adverse influence.
Summary of the invention
The utility model provides a kind of downdraft straw fuel gas stove in order to solve the problem that produces defective when existing straw fuel gas stove causes burning owing to unreasonable structure.
The utility model is to adopt following technical scheme to realize: downdraft straw fuel gas stove, comprise body of heater, body of heater comprises the burner hearth that has charging aperture, have vertical air duct and blast tube between inboard wall of furnace body and the burner hearth, have the air inlet that communicates with air duct and outside air on the body of heater, inboard wall of burner hearth has the air inlet that communicates with blast tube, the burner hearth top is provided with the combustion chamber that is communicated with it, and the combustion chamber inwall has air unsaturated zone that is communicated with air duct and the combustion gas unsaturated zone that is communicated with blast tube.When using downdraft straw fuel gas stove, send into stalk in the burner hearth of body of heater by charging aperture, then stalk is lighted, stalk carries out burn incompletely under the effect of limited oxygen below the fire grate, at this moment straw burning will produce a large amount of combustible gases, combustible gas enters blast tube by air inlet and then moves upward under the effect of burning suction, enter the combustion chamber through the combustion gas unsaturated zone that communicates with it then, air inlet is sent air into air duct and is moved upward under the effect of pressure fan, enter the combustion chamber through the air unsaturated zone that communicates with it then, combustible gas and air mix in the combustion chamber, by below, the combustion chamber high temperature that straw burning produced, ignited and acutely burning in the combustion chamber, improved the daily efficient of cooking of people effectively, reduced the pollution of environment simultaneously.
Air unsaturated zone and combustion gas unsaturated zone are spaced, and the gas that enters the combustion chamber like this is with more uniform mixing, and the burning of combustion chamber will be more abundant also.
Downdraft straw fuel gas stove described in the utility model improves by the structure in the body of heater having been done cleverly, makes that the stove internal combustion is abundant, has improved the utilization rate of heat energy, and has reduced the discharging of polluting, and has simultaneously and processes simple, low cost and other advantages.
