The common structure of normal domestic use fire coal, combustion wood stove is in the inside of body of heater burner hearth to be set, and in the bottom of burner hearth grate is set, and sets out cinder notch below grate.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 burning of normal domestic use fire coal, combustion wood stove is insufficient, not only wastes fuel, and seriously polluted.
Normal domestic use fire coal, the burning of combustion wood stove are insufficient in order to solve, waste fuel and with serious pollution problem, have occurred a kind of secondary air intake furnace again.This secondary air intake furnace is provided with intake stack in body of heater inside, and communicate with the mixing chamber that is arranged on upper furnace, the mixing chamber top edge is distributed with venthole, makes the air that enters mixing chamber by intake stack to enter into upper furnace by venthole, reaches the purpose of secondary air.This secondary air intake furnace preferably resolves the problem of oxygen supply deficiency in the fuel combustion process.By the intake of control road and bridge and intake stack, can also make fuel form fuel gas, the air mixing after-combustion that fuel gas enters at stockhole and secondary in the oxygen debt burning of lower furnace portion.But,, make the complex structure of body of heater and volume, weight all bigger because this secondary air intake furnace is in body of heater inside intake stack to be set.
Summary of the invention
For solving defectives such as complex structure that prior art residential coal combustion, combustion bavin secondary air intake furnace exist and volume, weight are all bigger, the utility model proposes a kind of secondary air intake furnace.The utility model secondary air intake furnace is provided with the air intake through hole at body of heater outer setting intake stack on furnace shell top, and upper furnace is provided with the back taper burner, and the top of burner is provided with air admission hole.The utility model secondary air intake furnace simple in structure, easy, the easy row of preparation method does not need complicated step can produce the economical and practical secondary air intake furnace with energy saving and emission reduction effects.
The utility model secondary air intake furnace is at body of heater outer setting intake stack, be provided with the air intake through hole on the top of body of heater shell, mixing chamber is formed at back taper burner and furnace shell top, and the top of burner is provided with air admission hole, and mixing chamber top is provided with circular cover plate.
The utility model secondary air intake furnace is arranged on the intake stack of body of heater outside and is made up of body of heater shell and U type baffle plate, the both sides of U type baffle plate closely link to each other with the body of heater shell, make U type baffle plate and body of heater shell form inlet channel, wherein, described U type baffle plate is a strip, its cross section is the U type, and a termination is closed, and another termination is the opening shape.
The circular cover plate that the utility model secondary air intake furnace mixing chamber top is provided with is movable the arrangement.
