The specific embodiment

Below in conjunction with the drawings and the specific embodiments the utility model secondary air combustion chamber is further described.

Accompanying drawing 1 is the three-dimensional structure schematic diagram of prior art rural area residential coal combustion, combustion bavin kitchen range, among the figure, and the 1st, the kitchen range top, the 2nd, burner hearth, the 3rd, grate, the 4th, charge door.As seen from the figure, the common structure of prior art rural area residential coal combustion, combustion bavin kitchen range is in the inside of the kitchen range top 1 burner hearth 2 to be set, and in the bottom of burner hearth 3 grate 3 is set, and sets out cinder notch below grate, at an end of burner hearth fuel inlet 4 is set.Air required during fuel combustion enters from grate or burner hearth top edge, therefore, need stir fuel through the instrument of poker one class commonly used, perhaps from the grate bottom with fuel combustion after ashes remove, to guarantee the oxygen abundance.Obviously, the fuel of prior art rural area residential coal combustion, combustion bavin kitchen range is primary combustion, and under the inadequate situation of oxygen, it is insufficient to be easy to burn, and not only wastes fuel, and seriously polluted.

Accompanying drawing 2 is positive schematic three dimensional views of the utility model secondary air stove core; Accompanying drawing 3 is reverse side schematic three dimensional views of the utility model secondary air stove core; Among the figure, the 2nd, burner hearth, the 501st, kitchen range core body, the 502nd, venthole, the 503rd, vent baffle, the 504th, charging aperture.As seen from the figure, the utility model secondary air stove core comprises kitchen range core body 501, venthole 502 and vent baffle 503, wherein, kitchen range core body 501 is uncovered column shape, kitchen range core body inside is burner hearth 2, vent baffle 503 be installed in the outside of kitchen range core body 501 and and kitchen range core body 501 outer surfaces between leave the gap, form inlet channel, the uncovered charging aperture 504 that is of kitchen range core body 501 1 end settings, the top edge of kitchen range core body 501 is evenly equipped with venthole 502, and venthole 502 directly communicates with atmosphere by inlet channel.

Specific embodiment 1

Accompanying drawing 4 is that the utility model secondary air stove core is installed in the schematic three dimensional views in rural area residential coal combustion, the combustion bavin kitchen range; Accompanying drawing 5 is that the utility model secondary air stove core is installed in the cutaway view in rural area residential coal combustion, the combustion bavin kitchen range, i.e. the A-A cutaway view of accompanying drawing 4.Among the figure, the 1st, the kitchen range top, the 2nd, burner hearth, the 3rd, grate, the 4th, charge door, the 5th, the utility model secondary air stove core, the 501st, kitchen range core body, the 502nd, venthole, the 503rd, vent baffle.When using the utility model secondary air stove core, only need a cylindrical cavity that internal diameter is close with the utility model secondary air stove core external diameter and highly close to be set in the centre of prior art rural area residential coal combustion, combustion bavin kitchen range, grate is installed in bottom in this cylindrical cavity, this column type hole of again the utility model secondary air stove core being packed into, and the charging aperture of secondary air stove core is overlapped with the charging aperture of the kitchen range top.Obviously, the utility model secondary air stove core can be imported oxygen by inlet channel and venthole at the stockhole place, the gas flow that produces when fuel combustion is during to the upper furnace edge, mix mutually with oxygen that venthole flows out and burn, not only make full combustion of fuel, can also reduce the pollutant of discharging in the gas, be the burner of energy-saving and emission-reduction in fact.If kitchen range top bottom is controlled by the air capacity that grate enters, when burn incompletely when making fuel combustion, the fuel gas of formation flowed to the upper furnace edge, with oxygen mix and burning that venthole flows out, the effect of its energy-saving and emission-reduction was more remarkable.

Specific embodiment 2

Accompanying drawing 6 is that the utility model secondary air stove core is not with the schematic three dimensional views of vent baffle embodiment; Accompanying drawing 7 is that the utility model secondary air stove core is not with the cutaway view in rural area residential coal combustion, the combustion bavin kitchen range of being installed in of vent baffle embodiment.Among the figure, the 1st, the kitchen range top, the 2nd, burner hearth, the 3rd, grate, the 4th, charge door, the 5th, the utility model is with the secondary air stove core of vent baffle, and the 501st, kitchen range core body, the 502nd, venthole.As seen from the figure, present embodiment has saved vent baffle 503, and the inwall that changes by kitchen range core body 501 and cylindrical cavity constitutes inlet channel, makes that the structure of the utility model secondary air stove core is more simple.But, when adopting not the secondary air stove core with vent baffle, need the inwall rule and smooth comparatively of the cylindrical cavity of the kitchen range top, and at high temperature indeformable, otherwise, in use for some time, cause the obstruction of inlet channel easily.
