Description

Horizontal multi-use coal-firewood furnace

The utility model relates to a kind of improved domestic burners, particularly a kind of horizontal type multi-function coal and firewood two purpose stove.

Before the utility model is made, can be used for the multifunctional furnace that cooking again can hot water heating in the family, great majority are vertical structures.Though can burn coal, burn bavin, also can only be to burn fuel such as some short crevices and straw burning on the bavin.Really resemble to burn and burn some long cornstalks the big bavin kitchen range.Field-crops such as kaoliang stalk, faggot, straw just seem and are suitable for very inadequately.Therefore, want to reach to resemble to burn and burn some long fuel the big bavin kitchen range, preferably adopt the horizontal type structure stove.But more existing horizontal type multi-function coal and firewood two purpose stoves, applicable performance is relatively poor, being provided with of the heating surface of heat exchanger (water jacket), because the restriction of structure is not ideal.It is bigger that the heating surface with heat exchanger that has is provided with in burner hearth, even fuel directly contacts with heating surface, makes that fractional cold is excessive in the burner hearth, the stove smouldering fire, and it is slow to cook, and the chemical loss of fuel is more serious, influences kitchener.It is fewer again that the heating surface with heat exchanger that has is provided with, and the most of heat that produces after the fuel combustion fails to be absorbed by the heating surface of heat exchanger, and has discharged outside the stove, and the flue gas heat loss is more serious.Therefore the horizontal type multi-function dual-purpose stove that can not influence normal kitchener that uses in the existing family, in hot water heating, exerting oneself of stove is all smaller, with radiator quantity also just fewer.

The purpose of this utility model is: provide a kind of extremely to be suitable for the normal cooking of can doing of family life and use.Can hot water heating exert oneself greatly again, burning coal, burning bavin two are suitable for the horizontal type multi-function coal and firewood two purpose stove that the thermal efficiency is higher.

The purpose of this utility model is finished as follows: the structure that is provided with stove gate, grey doorway, exhaust opening, crater of body of heater having been made a drum shape closed at both ends; Settle fire door, Hui Men, smoke evacuation tube, combustion-supporting on the body of heater and on the crater on the body of heater, be provided with the boiler face that to place 3 to 4 stove circles; Be provided with in body of heater inside and be connected with body of heater, the cross section is a semicircular arc, the heated sheet of the sandwich of end sealing; The corresponding section of heated sheet top and body of heater crater, have a φ 100 to φ 300 diameters all can the hole, and on this hole, be provided with one can be according to the inner roof brick that takes out or put into the difference of stove character; Be provided with a cast iron combustion chamber that is supported in the body of heater below the heated sheet in body of heater.When kitchener, inner roof brick on the heated sheet is taken off, cooker (pot) is placed on the Lu Quan position of boiler face, fire door, Hui Men are opened, fuel inserted in the combustion chamber by fire door burn, the hole of the flame that produces after the fuel combustion at this moment by having on the heated sheet, the crater on body of heater enters the boiler face bottom and burns to the bottom of a pan, supply cooking discharges out of the furnace by the smoke evacuation tube with fire, gas fume after burning.When stove is used in heating, can with the hole on the heated sheet with inner roof brick, cover.Stove circle on the boiler face is put well, after at this moment flame that produces after the fuel combustion and flue gas fill brush heated sheet inner surface, flowed to the smoke evacuation tube behind the front portion of pile warp body of heater and the back side of heated sheet, be discharged to outside the stove.The combustion chamber has been owing to adopted the both sides of flute profile that the structure of side plate is arranged in addition, the water-cooling wall interval of fuel burning and body of heater and heated sheet in the combustion chamber certain distance, so ignition temperature is higher, fuel can be fully burned in the combustion chamber.

When no matter stove is used in above-mentioned kitchener or heating, when very hot oven or discovery have the phenomenon of falling the cigarette if desired, the ash door can be shut, the starting combustion-supporting, in burner hearth air blast combustion-supporting, draw cigarette to smoke evacuation tube injection wind.Thereby not only can reach and burn coal, burn bavin two and be suitable for, promptly not influence and do normal kitchener, it is big to exert oneself in hot water heating again, the purpose that the thermal efficiency is high, and also this stove also has the characteristics that wind-fall cigarette, quick combustion, firepower dash of not violating.

The utility model compared with prior art, applicability is good, heat is imitated highly, fuel combustion is abundant.Do not violate the wind-fall cigarette.
