Pipe 2,4 going out gas branch pipes 2 are connected with smoke evacuation supervisor 1, so ensure that the uniformity that gas fume of combustion chamber is discharged, reduce to burning
The impact of flow of flue gas in room, improves stability.
It should be noted that because the heat transfer wall of bottom of combustion chamber is maximum by the lateral shear stress in coal seam in carbonization chamber 12
, the reasonable altitudes of the first cavity 10 should be the 1/7-1/4 of combustor height, if the first cavity 10 excessive height, that is, is more than combustion
The 1/4 of burning room height, and there is no the support of quirk partition wall 4, the stability in the large of body of heater can be greatly reduced;If the first cavity 10
Highly too low, that is, it is less than the 1/7 of combustor height, easily causes that in the first cavity 10, local pressure is too high, may lead to burn
In each quirk in room, the distribution of flue gas is not uniform.
The work process of the hot combustion gas of above-described embodiment is as follows:Heat smoke enters the first cavity 10 from air inlet 7, through combustion
Burn each quirk 5 in room, enter top of combustion chamber the second cavity 11, high-temperature flue gas are gradually incoming by heat during rising
In carbonization chamber, flue-gas temperature constantly reduces, and discharges low-temperature flue gas finally by going out gas branch pipe 2, smoke evacuation supervisor 1.
