Abstract
A novel fuel-saving furnace air supply system is composed of an annular air supply pipe and an air inlet. The outer side of the annular air supply pipe is communicated with the air inlet while the inner side is internally tangent to the lower edge of the inner wall of a fuel-saving furnace. A plurality of air holes are uniformly distributed on the annular pipe. Each air hole and the furnace inner wall are at an included angle ranging from 30 degrees to 45 degrees. In this way, the air and combustible gas can be fully mixed. The combustion efficiency is then improved. The air supply system (the annular air supply pipe) makes a fuel chamber separated from a combustion chamber. During a combustion process, flames which are only generated in the combustion chamber are closer to the furnace port and can directly act on a pan bottom. The loss of heat on the furnace body is then reduced. The heat using efficiency can be enhanced then. The fuel chamber which does not join in the combustion process will generate no dust. The temperature of the inner wall of the fuel chamber is obviously lower than that of the combustion chamber. The oxidation of the furnace wall is then decelerated. The service lifetime of the furnace body is thus prolonged.
Description
Technical field
The utility model relates to the air feed system of family expenses firewood-saving stove, particularly the firewood-saving stove of northern indoor use.
Background technology
Present employed firewood-saving stove mostly adopts natural air inlet, and shortcoming is that burning is insufficient, at the bottom of the flame temperature; The perhaps air feed from burner hearth below, shortcoming is to produce a large amount of dusts.Both common problems that exist be the position of stove fire burning all near comburant, to lose the part heat on the one hand, can fall the service life of end body of heater on the other hand.
Summary of the invention
Shortcomings such as firewood-saving stove efficiency of combustion in combustion process is low in order to overcome, the generation amount of dust is big, service life body of heater is short, this utility model solves the problems referred to above.
The utility model solves the technical scheme that its technical problem adopted: air feed system is made up of annular air feed pipe and air admission hole.Annular air feed pipe is outside to be connected with air admission hole, and the stove inwall lower edge of inner and firewood-saving stove is inscribe mutually, and the ring pipe top is the some pores of distribution evenly, pore and stove inwall angle 30～45 spend between, air is mixed fully with combustible gas.Annular air feed pipe in the air feed system separates fuel chambers with the combustion chamber, in the combustion process, flame only produces in the combustion chamber, and flame more can directly affact the bottom of a pan near fire door, reduces the thermal loss on body of heater, helps improving the service efficiency of heat; Fuel chambers is not participated in combustion process, can not produce dust; The fuel chambers inner wall temperature obviously will be lower than the combustion chamber, has slowed down the speed of furnace wall oxidation, the service life of having improved body of heater.
The benefit of the utility model is to improve the utilization rate of comburant, can practice thrift large number of biological matter resource; Minimizing is because of insufficient a large amount of discharge of harmful gases that produce of burning; Reduce dust generation in the firewood-saving stove use, purified the environment in kitchen; Increased the service life of body of heater.
Description of drawings
Fig. 1 is the vertical section structure figure that the utility model combines with body of heater.
Fig. 2 is the air feed system structure chart
Among the figure: 1 ash hole, 2 fire grates, 3 fuel chambers, 4 air admission holes, 5 combustion chambers, 6 stove inwalls, 7 furnace outer walls, 8 energy circulation mouths, 9 annular air feed pipes.
The specific embodiment
Air feed system is made up of with air admission hole 4 annular air feed pipe 9.Annular air feed pipe 9 outsides are connected with air admission hole 4; Stove inwall 6 lower edges of inner and firewood-saving stove are inscribe mutually, ring pipe top some pores that evenly distribute, pore and stove inwall angle 30～45 spend between; Air is mixed with combustible gas fully, improve efficiency of combustion.Air feed system passes through energy circulation mouth 8 with the few part in the heat of combustion chamber internal combustion generation; Passage between stove inwall 6 and furnace outer wall 7 is transported in the fuel chambers 3 fuel gasification, at the circulation that produces through annular air feed pipe 9 combustible gas is drawn into the combustion chamber and burns.Annular air feed pipe 9 in the air feed system separates fuel chambers 3 with combustion chamber 4, in the combustion process, flame only produces in combustion chamber 4, and flame more can directly affact the bottom of a pan near fire door, reduces the thermal loss on body of heater, helps improving the service efficiency of heat; Fuel in the fuel chambers 3 is not participated in combustion process directly, can not produce dust; The fuel chambers inner wall temperature obviously will be lower than the combustion chamber, has slowed down the speed of furnace wall oxidation, the service life of having improved body of heater.
