At the burning initial stage, because combustion instability and combustion gas are few, the flue gas of this moment can not be lighted at burner, it is by 22 emptyings of emptying valve, through behind the certain hour, the fuel gas ratio is increased in the time of forming the burner burning gradually in the flue gas, close emptying valve 22, open air door 13 and burnt gas valve 12, the fuel gas of body of heater 30 upper spaces from the side row's Gas Pipe 32 under the driving of self-produced pressure enters the gas downflow pipe 40 of water tank, change direction with the water collision back in the sedimentation Rose Box 24, enter combustion gas ascending tube 39, again by entering gas downflow drain 42 after the combustion gas transition conduit 41, outlet enters combustion gas transition case 25, combustion gas is in combustion gas transition case 25 and water surface generation secondary collision, and the dust in the combustion gas mixes that under the effect of the absorption of sedimentation and water combustion gas is purified when twice and water collision.Combustion gas enters external Gas Pipe 11 then, this combustion gas and enter infrared burner 15 ignition of internal combustion heat accumulating type after the air that air hose 10 feeds mixes by burnt gas valve 12 and air door 13 allotments.
Material is in the process of burning aerogenesis, as flame occurs and diminish, unstable, phenomenon appearance such as flue gas are arranged, tackle fired state and adjust, the method for adjustment has two kinds, and first kind is stirred handle 38 with rotation and drive 28 rotations of stirring air guide block, lifting, make the redistribution of burning-point and material, improve fired state.Second kind is to make platen 16 remove to promote material with pusher grip 21 back and forth movements after unscrewing lock-screw 205 to move, and improves fired state by the way of compacting material.Generally speaking, under the effective situation of first method, can not use second method, only improve little or improve under the short situation of back good combustion state duration and be used in combination second method again in first method, we are by facts have proved, being used of these two kinds of methods can reach the effect that adjusts good combustion in the sealing body of heater fully.
After normal use a period of time, burn most ashes from the little tapering of furnace lining 8 deposition upwards gradually, arrived to a certain degree will influence the burning air feed and the redox of material, influence the generation of combustion gas, at this moment, can take dual mode adjustment, a kind of is to rotate dump grate 23 to discharge unnecessary after-flame ashes, another kind is that 27 rotations of handle 38 drive activity air-guide rods are stirred in rotation, the rotation of movable air-guide rod 27 will and be stirred at dump grate 23 and be formed an air duct between the air guide block 28, can guarantee for air continuous.
After normal use a period of time, to constantly produce from the tar in the body of heater flue gas, dust, moisture, wherein tar and water condensation and flowing in the sedimentation Rose Box 24 in pipeline, dust is except that a part sticks to tube wall, another part falls in the water owing to taking place to impact with the water surface of sedimentation Rose Box 24 and combustion gas transition case 25, is suspended in part dust in the water and unnecessary condensed water and constantly is discharged to outside the body from oblique overflow pipe 7 together.Tar and part soot particle then are deposited to the bottom of sedimentation Rose Box 24 gradually, when reaching the amount of need discharging, should open coke discharging throttle 1, can make things convenient for and discharge tar completely.
After normal use a period of time, the dust or the dust blended tars that stick to tube wall increase gradually, and final possibility blocking pipe, outside phenomenon then show as not aerogenesis or aerogenesis very little, at this moment can use the dust blended tars of everywhere block clearing pole pair row Gas Pipe 32, gas downflow pipe 40, combustion gas ascending tube 39, combustion gas transition conduit 41, gas downflow drain 42 tube walls to clear up and dredge, normally supply gas to guarantee pipeline, this gasification furnace all can be cleared up and be dredged when operation and inoperative, and burning is interrupted.
