The operation principle of whirlwind air deflector 200 is: owing to body of heater 100 is the cavity closed, fuel fires
Forming air pressure during burning, granular fuel burns in burner hearth 121 and produces the fuel gas with dust,
Fuel gas enters whirlwind air deflector 200 through the opening of burner hearth 121 under the influence of air pressure, flammable
Gas respectively enters first passage 211 and second channel 221.
1. the gas of entrance first passage 211 is under the effect of guide vane 230, forms cyclone, can
Combustion gas body enters fuel gas mixing chamber 131, and the big dust in fuel gas is in the effect of centrifugal force
Under, thrown to the sidewall of the first housing 101, due to action of gravity, big dust is along the first housing 101
The dust that force-lands in dust-storage chamber 132, dust-storage chamber 132 of sidewall enter burner hearth 121 through ash leakage hole 105
In；Little dust in fuel gas force-lands in rotary course in dust-settling compartment 222, plays collection
The effect of dust；Trickle dust in fuel gas is under the influence of air pressure through crater 111 and go out
The first through hole 112 near burner 111 sprays, it is achieved cleaning burning.
2. the least due to the aperture of the second through hole 241 and third through-hole 243, the second through hole 241
Little dust and trickle dust can be allowed to pass through, and third through-hole 243 can only allow trickle dust to lead to
Crossing, the big dust entered in the fuel gas of second channel 221 cannot pass through the second through hole 241 He
Third through-hole 243, can only force-land in burner hearth 121；And little dust in fuel gas and trickle
Dust enters fuel gas mixing chamber 131 through the second through hole 241, and little dust is under the effect of cyclone
Force-landing in dust-settling compartment 222, trickle dust is under the influence of air pressure through crater 111 and crater 111
The first neighbouring through hole 112 sprays, it is achieved cleaning burning.
Fuel burns in burner hearth 121 and generates the most uneven fuel gas, and a part is through being in
Spontaneous combustion is formed during the whirlwind air deflector 200 of the condition of high temperature；Another part enters fuel gas mixing chamber 131
Forming air-flow, air-flow is formed with the oxygen in fuel gas mixing chamber 131 in rotary course uniformly
Fuel gas, uniform fuel gas is in crater 111 ejection burning, it is achieved that metastable,
The most sufficiently burn, reduce the discharge of waste gas.
In this example, spiral air-conducting combustion furnace 1000 can also but be not limited to that there is gas-collecting structure 300,
