Description

Horizontal cooking heating is bathed and is used coal stove

The utility model relates to a kind ofly makes the heat power equipment of thermal source with coal, and particularly a kind of civilian cooking heating Loose-coal stove can be used as the heating of rural area and city dweller's dwelling house, unit, family's cooking, bathe in order to and the compact heat source of other hot water supply.

At present, the cooking of using in the prior art, heating coal furnace, its kind day by day increases, but all is to belong to vertical grate furnace (being that coal burns below, the heat absorption top loading).It is set up heat absorbing sheet miscellaneous and realizes heat exchange by means of water jacket with in stove.All belong to the vertical grate furnace of this kind as Chinese utility model patent 87216128 and 90200056 and 96200388.The shortcoming that this type of furnace exists is that the combustion space is narrow, coal seam thick (250-300 millimeter), and gas permeability is poor, causes the high temperature anoxic easily, thereby very unfavorable to burning.Because burning is to carry out from bottom to top, when above the high-temperature flue gas baking during coal seam, the fugitive constituent in the coal is overflowed, owing to the high temperature anoxic, a large amount of fugitive constituents and CO gas can not fire burns, but run away in vain.Especially when banking up a fire or burn bituminous coal, this waste is up to 20-30%.Have only when the combustion high temperature district moves on to surface, coal seam (promptly seeing flare), fuel gas could fire burns.This just makes that the very high fuel gas of quite a few calorific value can not be burned, therefore causes the thermal efficiency low, and the heating effect is not good enough.If heating area is above 60 meters ²More than, the coal seam is thicker, and stove can be higher as a result for it, and it is also just very inconvenient to be used for cooking.

In order to overcome deficiency and the defective that prior art exists, the purpose of this utility model be for heating area bigger, the hot water demand measures many families and dwelling house provides a kind of horizontal cooking heating bath coal stove, make it have thermal efficiency height, burning and heat-transfer effect are good, not only heating, bathe with can meeting the demands, and cooking is also very convenient.

The utility model is achieved through the following technical solutions: it is mainly by furnace bottom, grate, tile, water jacket, grey chamber, chimney, parts such as heating surface are formed, the burner hearth outside is provided with outer water jacket, and water jacket is provided with water inlet and delivery port outside, it is characterized in that the L-shaped horizontal type structure of this coal stove profile, its body of heater inside is divided into left and right sides two parts, a part is the combustion zone, and another part is provided with heating surface for heat absorption district, heat absorption in the district.The heating surface in heat absorption district adopts the arrangement that combines with perpendicular horizontal water tube of chimney and double-layer water jacket stovepipe, and this horizontal water tube and outer water jacket, inner water sleeve link.

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is the A-A cutaway view of accompanying drawing 1.

Accompanying drawing 3 is the B-B cutaway view of accompanying drawing 1.

Describe concrete structure of the present utility model and preferred forms in detail below in conjunction with accompanying drawing: the utility model mainly comprises furnace bottom 1, grate 2, tile 3, outer water jacket 4, grey chamber 5, bell 6, fire door 7, water inlet 11 and delivery port 12, parts such as horizontal water tube 3 that being arranged on absorbs heat distinguishes and double-layer water jacket stovepipe.Body of heater adopts L shaped horizontal type structure, and is short and grow, and the stove right side is the combustion zone, and the left side is distinguished for heat absorption; Grate 2 in the combustion zone is bigger approximately by 30% than general vertical coal stove, and the combustion space is big, balk, good permeability, rich oxygen is many, thereby help coal fire burns.The fuel gas and the carbon monoxide of overflowing in the combustion zone also can be burnt fully simultaneously, not only effectively raises the thermal efficiency, and significantly reduced smoke discharge amount.This kind structure had both helped the abundant burning of coal, helped the layout of heating surface again.Promptly adopt horizontal water tube 8 as heating surface, and combine with vertical double-layer water jacket stovepipe in the heat absorption district.The double-layer water jacket smoke tube is made up of outer water jacket 4 and inner water sleeve 9.Horizontal water tube 8 is perpendicular with the flow of flue gas direction, and flame and high-temperature flue gas be this endothermic tube of transversal flow directly, can obtain best heat exchange effect like this, makes exhaust gas temperature fall very lowly.

For further improving temperature in the stove, burner hearth three faces are coated with flame-proof thermal insulation material.

Be not to be pressed in above the coal seam with lid when banking up a fire, but be provided with chimney door 10 on chimney, its objective is with it and regulate furnace temperature, all heat-absorbent surfaces in the stove all are under the certain temperature condition like this, reduce heat loss, the efficient height, and heating effect is good.

The utility model compared with prior art has the following advantages and beneficial effect: this coal furnace is owing to adopt Use horizontal type structure, short and grow, and be divided into combustion zone and heat absorption district two parts, the combustion space is bigger on the one hand, Balk, good permeability, be conducive to coal water burning and burning; The flammable gas of the fugitive constituent of overflowing simultaneously Body and carbon monoxide can be fully burned, so thermal efficiency height, and heat is big. On the other hand, in the heat absorption district Arrange horizontal water tube, can directly be subjected to the transversal flow of flame and high-temperature flue gas, thereby obtain best heat exchange effect What really, exhaust gas temperature can fall is very low. Therefore this coal furnace, hot water demand amount big to heating area not only More family and dwelling house can meet the demands, and cooking is also very convenient.
