Description

Multipurpose energy-saving coal-burning gas stove

The utility model belongs to daily necessities, definite a kind of stove and accessory of cooking and warming oneself of being used to of saying so.

How stove and accessory before the utility model though have the function of the cooking and heating, can not utilize steam added combustion." blue streak " stove (number of patent application: though NO.86801860) have a function of utilizing steam added combustion, but the problem that has following several respects in using: (1) steam generator is single step arrangement, generator installation site on body of heater is low, vertically coverage is little, is just lighting a fire, and contains fiery mistake, the burner hearth accumulated slag, when lower furnace portion temperature of a specified duration is low during banking, can not guarantees to produce steam continuously, and then influence the effect of combustion-supporting and energy-saving.(2) warmer water jacket profile is a cylinder, and the heated vertical area is little, and the Inlet and outlet water dividing plate does not have technology to guarantee in the water jacket, and at utmost spot welding on one side.Hot and cold water is easily walked short circuit, and the water jacket samdwich gap is big, Rong Shuiduo, and heat exchanger effectiveness is low.(3) combustion chamber and furnace wall are fired into one with high-temperature refractory, slag often with the burner hearth sintering together, scarfing cinder destructible hearth wall, and be difficult for repairing, local damage, integral body is scrapped, lack service life, special part is purchased difficulty.(4) stove bamboo or wicker fence, chimney, furnace access cap design owe rationally to have influenced the vaporization combustion-supporting effect, and UTILIZATION OF VESIDUAL HEAT IN is insufficient.

Task of the present utility model provides a kind ofly can utilize steam added combustion, thermal efficiency height, the stove and accessory of multiple functions such as UTILIZATION OF VESIDUAL HEAT IN fully, good energy-conserving effect, manufacturing be easy to maintenance, have culinary art, scorch, waste heat heating, waste heat burning drinking water.

This stove and accessory, profile is cabinet type body of heater, mainly comprises: furnace body frame (1), safety exhaust (2), steam generator switch (3), steam generating chamber's switch (4), drink water tank (5), steam generating chamber (6), heating water jacket (7), fire door (8), flame lid (9), three air inlets (10), steaming and baking box (11) is scorched dish (12), operation board (13), stone or metal plate for standing a stove on as a precaution against fire (14), water jacket chimney (15), Inlet and outlet water joint (16), oven door (17), secondary air mouth (18), stove bamboo or wicker fence (19), sealing ring (20), lifting water seal box (21), conducting strip (22), mud combustion chamber (23), furnace wall (24), steam generator (25), overflow pipe (26), an air inlet (27), insulation material parts such as (28).As improving invention.The utility model adopts the two-stage steam generator, and the generator junction of the edges of two sheets of paper is welded on the furnace wall, and the inboard protruding furnace wall of advancing is equipped with conducting strip on the generator madial wall, with fixing mud combustion chamber, and the enhancing heat-conducting effect.The furnace wall is enclosed to make with metal sheet and is pulled out slightly (frustum) shape, and the inboard, furnace wall is provided with conducting strip, and combustion chamber pastes with prescription earth.The heating water jacket is for pulling out slightly (frustum) shape, and is provided with the Communicating device water jacket that can make the Inlet and outlet water shunt.Water trapping layer adopts little gap, and surrounding wall is provided with some combustion-supporting holes.The bottom, furnace wall is provided with the secondary air mouth, and stock cap is two-layer inside and outside oblong is divided.Bocca is covered with four and penetrates fire jetting hole, and has designed sphere flame flap for warming oneself.The stove bamboo or wicker fence is made arch, can take off from the bottom, and can move forward and backward along the furnace bottom plane.

As further improvement, epimere is provided with the food steaming and baking box and scorches dish in the furnace wall, is provided with steam generating chamber in the steaming and baking box, the external water tank of drinking of generation chamber feed pipe, and the steaming and baking box bottom side is provided with safe exhaust steam valve.This stove and accessory is drunk and is had the hole corresponding with the water jacket of warming oneself on the water tank, and as three air inlets, one of them macropore is also as stoke hole.The intercalated water sleeve structure is made at the nearly stone or metal plate for standing a stove on as a precaution against fire of chimney place, and with drink water tank and be communicated with.

The stove and accessory of making according to the said structure feature, at first waste heat is drunk the water tank topped up with water before lighting a fire, open steam generator water inlet pipe switch, fill with the two-stage steamer generator, hear that the water seal box has water filling sound can close (water filling can supply to steam about two hours).After ready, can light stove fire, burner hearth heats up, and steam generator promptly produces steam.Steam is sent into air inlet one time at vapour pressure effect lower edge conduit, forms the vaporization turbulent flow at furnace bottom with the wind, enters the burner hearth burning zone by the stove bamboo or wicker fence and promptly resolves into fuel gas, just can play the combustion-supporting and energy-saving effect.After stove was lighted, the different intensity of a fire of utilizing multi-functional flame flap to produce can be finished and fry in shallow oil an affairs such as stir-fry, culinary art.Drink water tank and have the function of arcola, can boiled drinking water.After satisfied the drinking, hot water can be sealed in heating system, system water then can not flow back to potable water tank, has guaranteed drinking water hygiene.Put in the food steaming and baking box treat steaming food after, close chamber door, open steam generating chamber's switch by angle, hot water promptly injects steam generating chamber, produces a large amount of steam rapidly, adds the heat that upper furnace wall produces, and forms high pressure in the case, can cook food fast.

Adopt this novel stove and accessory,, saved the energy, improved utilization rate of waste heat greatly owing to effectively utilized steam added combustion.Burn the stove of 8-10 kilogram coal an every day, be interrupted every day with fiery 6-8 hour, except that cook, cooking and the supplying drinking water, can supply 5-10 people's bath in a tub or shower season not warming oneself.Can be with four assembly cover radiator season in heating, live the chamber for 60-80 square metre and warm oneself, room temperature can reach the 15-20 degree.Do not influence fire door fry in shallow oil fry culinary art in, the food steaming and baking box can cook the steamed bun of 4-5 kilogram face or the food of equal volume about 20 minutes.This stove and accessory cost is a little more than the common iron furnace of equal volume, and production technology does not have specific (special) requirements, and the raw material wide material sources are made easily, manipulate simple and easy to do, safe and reliable.During the urgent need fire, available blower fan is combustion-supporting.Also can utilize steam added combustion during with natural wind.Reached energy-conservation, UTILIZATION OF VESIDUAL HEAT IN is abundant, multi-functional, high efficiency purpose.
