Description

Normal pressure system gas heating stove

Technical field

The utility model belongs to the improvement of stalk producer structure, particularly normal pressure system gas heating stove.

Background technology

At present, the stalk producer is progressively popularized in the vast rural area of China as a kind of energy-efficient kitchen range simple in structure, the use cleanliness without any pollution.The stalk producer normally is being provided with air admission hole in the bottom of burner hearth, on the body of heater of burner hearth end face seal cover is being set, during use stalk or coal etc. is being put into burner hearth, building seal cover, smoldering makes fuel gas such as methane or carbon monoxide, the use of heating up water for cooking under anaerobic condition.Though existing stalk producer can be competent at family's cooking work well, but its function of use is single, for the vast rural area of northern China, because will cook with the heating of coal stove winter usually, therefore, to winter, the stalk producer will be left unused waits until that weather warmed up and re-used the beginning of spring in the coming year, stalk producer utilization rate is low, causes very big waste.In addition, traditional straw producer generally just plays the effect of producing fuel gas, if use as heating stove with it, then has the low deficiency that waits of heat energy utilization rate.

The utility model content

The purpose of this utility model is to provide a kind of normal pressure system gas heating stove, and is not only simple in structure, be easy to make, and low production cost, and integrate system gas and heating function, heat energy utilization rate height can round-the-clockly use, utilization rate height, energy-saving and environmental protection.

The purpose of this utility model is achieved in that a kind of normal pressure system gas heating stove, comprise body of heater, the combustion chamber of for its end face seal cover being housed in the front portion of body of heater, the bottom level of combustion chamber is being provided with fire grate, on bottom, the combustion chamber internal perisporium of fire grate top air intake duct is being set, the smoke evacuation chamber of chimney is housed for its end face in the rear portion of body of heater, the smoke evacuation chamber is communicated with by flue with the combustion chamber, body of heater around the combustion chamber is for having into, the water jacket furnace of delivery port, outside being provided with in the combustion chamber above air intake duct, in, interior three spaces are sleeved on ring-shaped water jacket together, outward, in, the end face ecto-entad of interior three ring-shaped water jackets reduces gradually, the end face of three ring-shaped water jackets is interconnected by uniform ringwise slope cyclic water pipe and water jacket furnace successively, the low and end position height that links to each other with outer ring water jacket and water jacket furnace of the end position that each slope cyclic water pipe links to each other with interior ring-shaped water jacket; The retaining cigarette turnover panel that is complementary with the chimney internal diameter is being set in the chimney, on the top furnace body wall of smoke evacuation chamber the combustion gas escape pipe is being set.

When the utility model uses as heating stove,, three ring-shaped water jackets are being set in the combustion chamber, therefore can making full use of the heat energy that the combustion chamber fuel combustion produces because the body of heater around its combustion chamber is the water jacket furnace that has entery and delivery port; Outside adding, in, the end face ecto-entad of interior three ring-shaped water jackets reduces gradually, the end face of three ring-shaped water jackets is interconnected by uniform ringwise slope cyclic water pipe and water jacket furnace successively, low and the end position height that links to each other with outer ring water jacket and water jacket furnace of the end position that each slope cyclic water pipe links to each other with interior ring-shaped water jacket, the bubble that produces in the water jacket is risen in the water jacket furnace along the slope cyclic water pipe, help reducing the circulation resistance of water in water jacket furnace and the ring-shaped water jacket, heat absorption is abundant, heat energy utilization rate height.

When the utility model uses as producer, close the retaining cigarette turnover panel that is provided with in the chimney, in the combustion chamber, put into fuel compacting smolderings such as kindling material and stalk, coal, ventilate in the combustion chamber by air intake duct, it is indoor that the fuel gas that produces enters smoke evacuation along flue, through contact the moisture that cools and isolates wherein with the smoke evacuation locular wall, the combustion gas escape pipe discharge that is provided with on the top furnace body wall by the smoke evacuation chamber use of heating up water for cooking again.

The utility model is not only simple in structure, is easy to make, and low production cost, and integrate system gas and heating function, heat energy utilization rate height can round-the-clockly use, utilization rate height, energy-saving and environmental protection.
