Description

Coal, firewood two-purpose energy-saving warming air stove

The utility model relates to a kind of civilian coal and firewood two purpose hot-blast stove.

At the vast northern area of China, algid stage, is longer, cook a meal with and the fuel used consumption of warming oneself very big, and general general native cooking stove among the people, the thermal efficiency is extremely low, and in the last few years, people had developed diversified energy-saving stove, to energy-conservation certain effect has been arranged, but some exists different some shortcomings parts.

In known technology 1, the general adjustable wet energy-saving firewood stove that reaches the popularization of scientific and technological development company in Beijing has the twin furnace mouth.Flame under the fire door through another fire door, heats another cooker after the cooker on the fire door is heated, and just drains then, so thermal efficiency height.But its function singleness can not heat to the room.And northern area for save time, the fuel saving, cooking and the heating carry out simultaneously.So this firewood-saving stove not too is suitable for northern area.

In known technology 2, the general general civilian small-sized hot-water heating soil boiler in the north.This easy heat supply stove, the thermal efficiency is very low, has a large amount of carbon dusts and carbon monoxide to drain with waste gas during burning, the severe contamination air.And need conveyance conduit and fin, inconvenience not only is installed, and the cost height, so penetration and promotion has certain difficulty.

The purpose of this utility model is: a kind of energy-conservation hot-blast stove of civilian coal and firewood two purpose that is suitable for northern usefulness is provided.It is not only more energy-conservation, and adopts hot air heating, and has small oven, and it has heating wind, cooks food, the baking cake carries out simultaneously, the characteristics that are independent of each other.

The utility model is achieved in that the stone or metal plate for standing a stove on as a precaution against fire that band twin furnace mouth is housed on body of heater, be provided with the burner hearth lining in the body of heater, and the periphery of lining has combustion tube to lead to the fire door place.When stove is worked, the fuel combustion in the burner hearth, flame rises to the fire door place, and combustion tube is transported to the fire door place to fresh air simultaneously, mixes mutually with flame, and interior contained carbon and the carbon monoxide of flame acted on mutually, forms burning for the second time, so improved combustion rate.Heating wind is achieved in that is provided with air admission hole on body of heater, and the air of outside enters cavity between body of heater and the burner hearth lining by air admission hole, absorbed the heat that the burner hearth lining discharges, the hot-air that forms prolongs cavity and rises, and cavity is transported to the chamber of living that needs heating by warm braw row mouth behind stove.Inside at stone or metal plate for standing a stove on as a precaution against fire is equiped with baking box, can the baking cake.

For the indoor temperature that is heated is controlled easily, control valve is equipped with at the place at warm wind port, controls the flow of its output hot blast.

Because the utility model has added combustion tube in body of heater, surplus carbon and carbon monoxide in the flame are fully burnt,, reduce the pollution of air so improved the combustion rate of the thermal efficiency and fuel.Isolated owing to obtaining with burner hearth in the cavity of hot-air outside the burner hearth lining simultaneously, so cooking is carried out simultaneously with heating, be independent of each other, and avoided the pollution of flue gas the hot-air that heats.Owing to increased baking box, the more convenient need of people's life food.

Fig. 1 is a front view of the present utility model, and Fig. 2 is a vertical view, in order to understand the structure of stove intuitively, the left view that do not draw, and the right view 3 that draws.Fig. 4 is the baking tray in the baking box.

Below in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, explanation material object of the present utility model and operating position.

The energy-conservation hot-blast stove of this coal and firewood two purpose comprises body of heater＜1 〉, body of heater＜1〉links to each other with top stone or metal plate for standing a stove on as a precaution against fire＜2 〉, stone or metal plate for standing a stove on as a precaution against fire＜2〉is provided with fire door＜3〉and fire door＜4 〉, and waste gas row mouthful＜6〉and warm braw row mouthful＜7〉are arranged on stone or metal plate for standing a stove on as a precaution against fire＜2 〉, in warm braw row mouthful＜7〉control valve＜16〉is housed.What a level was arranged in the stone or metal plate for standing a stove on as a precaution against fire＜2〉is divided into bilevel dividing plate＜8〉to stone or metal plate for standing a stove on as a precaution against fire＜2 〉, be provided with ring-type fire door inwall＜9〉around in the fire door＜3〉on dividing plate＜8〉upper strata,＜4 〉, dividing plate＜8〉lower floor is positioned at fire door＜4〉one ends baking box＜5 〉, baking tray can be inserted in the inside of baking box＜5 〉, sees Fig. 4.Body of heater＜1〉middle and lower part is provided with air admission hole＜11 〉, there is the stove bamboo or wicker fence＜14〉of bottom in the burner hearth lining＜10〉that can take out and the lining inside of body of heater＜1 〉, has the same dividing plate of combustion tube＜12〉＜8〉to link to each other in the cavity＜21〉between burner hearth lining＜10〉and the body of heater＜1 〉.There is the annular that is attached thereto the interior bottom of body of heater＜1〉every dust plate＜13 〉.Body of heater＜1〉communicates with the cavity＜19〉of ring-type fire door inwall＜9〉back with cavity＜21〉between the burner hearth lining＜10 〉, and communicates with warm braw row mouthful＜7 〉.

The energy-conservation hot-blast stove of this coal and firewood two purpose in use, filling coal or bavin in burner hearth＜15 〉, light and normal combustion after, locate to form flame at fire door＜3 〉, while combustion tube＜12〉is transported to fire door＜3〉to fresh air and is located, and mixes mutually with flame, form burning for the second time, surplus carbon and carbon monoxide in the flame are fully burnt, and flame prolongs arrow＜18〉direction through fire door＜4 〉, is discharged by waste gas row mouthful＜6 〉.Waste gas row mouth, available chimney directly links to each other with the open air and communicates, and also can directly feed in the heatable adobe sleeping platform.This energy-conservation hot-blast stove heating process is such: outside air＜17〉is entered in the body of heater＜1〉by air admission hole＜11 〉, absorbed the heat that burner hearth lining＜10〉discharges, form hot-air, because hot-air proportion is less than normal temperature air, so hot-air rises naturally, prolong arrow＜20〉direction and discharge from warm braw row mouthful＜7〉via cavity＜19 〉.Warm braw row mouthful＜7〉directly communicates with the room that needs heating with carrier pipe.The speed that warm braw control valve＜16〉is discharged in order to the control warm braw, thereby control room temperature.Can insert baking tray in the baking box of this energy-conservation hot-blast stove＜5 〉, see Fig. 4, in order to roasting various cakes, the heat of baking comes the bottom to fire door＜4 〉.
