Abstract

The utility model discloses a civil energy-saving cooking stove, which is provided with a fireproof bulkhead, a combustion chamber, a flue, a stove plate, a secondary blast pipe and a porous metal plate in the stove chamber except the general structure of a cooking stove. The civil energy-saving cooking stove makes fume detour to the flues of the two sides of a cooker in order to be discharged from the cooker bottom to the door of the combustion chamber, which can make the heating of the fume be utilized for two times. The civil energy-saving cooking stove can use gas and solid as fuel. The utility model has the advantages of energy saving, convenient operation and low cost.

Description

Civil energy-saving cooking stove

The invention belongs to a kind of energy-saving cooking

Present widely used cooking stove is all continued to use traditional structure situation: promptly the cooking stove of making fuel with coal, bavin is made up of body of heater, burner hearth, siege, fire door, bell; And the cooking stove of making fuel of gases such as coal gas, biogas is made by conduit and stone or metal plate for standing a stove on as a precaution against fire.

Existing cooking stove weak point is: cooking stove can not dual-purpose gas, two kinds of fuel of solid; Fuel can not make full use of, heat is dispersed into the space, waste energy contaminated environment.

Purpose of the present invention, be manufacture and design a kind of good energy-conserving effect, pollute little, the practical cooking stove of available pluralities of fuel, this cooking stove makes according to the circuitous once more widely different utilization of flue gas heat, twice aeration and heat reflection principle.

Accompanying drawing 1 is a burner hearth inner structure schematic diagram

Accompanying drawing 2 is along I-I line cutaway view among Fig. 1

Cooking stove of the present invention and existing cooking stove relatively have following difference:

(1), in burner hearth, be provided with a firebreak 1 greater than half garden shape with certain altitude and thickness, chimney and combustion chamber 2 are separated, directly enter chimney so as not to flue gas.Combustion chamber 2 is the garden cylindrical spaces that surrounded by firebreak 1, is the place that produces heat, and high 200-230mm, diameter are 120-160mm.After pan 10 placed on the combustion chamber 2, the Lower Half of pot was just imbedded in burner hearth bell under, and the outside of imbedding burner hearth inner pan body part like this is exactly a flue 5, and communicates with chimney.Select different bell circles for use according to pan 10 diameter differences.Firebreak 1 is available metal material or the refractory brick that refractory material is made.

(2), close combustion chamber 2 one sides on firebreak 1, by adorning a seamless steel pipe the same with bore on the combustion chamber 2, that be drilled with aperture, should manage closed at both ends, at the appropriate location of pipe opening, and join with the nozzle 9 that has control valve and to constitute stone or metal plate for standing a stove on as a precaution against fire 6, this stone or metal plate for standing a stove on as a precaution against fire 6 also available metal casting forms, this sample cooking stove just constitutes the practical cooking stove that can distinguish burning solid, two kinds of fuel of gas, side at cooking stove has secondary air channel 8 to lead to combustion chamber 2 to help burning, and this pipe is that diameter is the metal tube of 30-50mm.

(3), 2 one of placement suitable for reading have certain thickness multiple metallic plate 7 in the combustion chamber, have the combustion-supporting effect of heat accumulation and radiant heat, this plate can be made of the ferrous metal of 8-10mm thickness, the aperture can be 8-12mm.Pan 10 is put on the dry plate when using this plate, and the time spent is not taken off this plate, pan 10 directly place combustion chamber 2 suitable for reading on.

This cooking stove operation principle: fuel is after 2 burnings of combustion chamber, most of heat has been absorbed by pan 10, and flue gas by the bottom of a pan through combustion chamber door 3 circuitous widely different above combustion chamber 2 flue 5 in pan 10 outsides, waste heat is absorbed once by pan 10 again in the flue gas, because pan 10 heating surface areas double above, prolonged heated time, take full advantage of heat, when closing upper furnace door 4, combustion chamber 2 is semienclosed, but prolonging burning time can effectively utilize fuel. The methods such as recycling heat radiation and twice aeration make combustion chamber 2 maximum temperatures reach 1150 ℃, and it is 750 ℃ that common cooking stove is discharged flue-gas temperature, cooking stove combustion of the present invention The temperature degree is below 320 ℃.

This cooking stove energy-saving efficiency height, solid fuel can save 60%, and gaseous fuel can be saved more than 30%, and this cooking stove can be used pluralities of fuel, and is easy to operate, cheap, is widely used.
