Operation principle:
When initial, all valves are in closed condition, and combustion furnace is in the state of banking up a fire.
While starting combustion furnace, start power supply and gearbox 4, open A chip removal mouth valve 22, A output 5 drives horizontal helicalRevolve 7 rotations, fuel enters horizontal feed pipe 9 from funnel 1, by flat spin 7, fuel is delivered to vertical feed pipe 23, then by hanging downStraight spiral 26 is sent fuel into burner hearth through burner hearth feed pipe 45, when burner hearth fuel height reaches material level tablet 64 positionsTime, material level tablet 64, by fuel jack-up, starts to control material level inductor 54 by material level induction rod 55, and feeding mechanism stops fortuneOK.
In fill process, the bits shape thing in fuel is by the inclined-plane of chip area 12 or chip removal mesh 25 or vertical spin 26 or hang downThe gap of straight spiral 26 and vertical feed pipe 23 falls between chip removal web plate 24 and the upper surface of vertical spin bearing 18,Discharge from A chip removal mouth 21 by scraping bits plate 13. Mainly in order to reduce the bits shape thing in fuel, thus the Mars while reducing burningAnd Mars ash.
Open fire banking-up board 65, igniting burnt gas valve 51, some windburn band valve 53, crater air intake valve 57, annular windRoad valve 34, lower air duct valve 30, spiral duct valve 19, pass through a some windburn band 61, igniting after igniting combustion gas and air mixWind band exhaust vent 63 arrives upper furnace 49 inside, initial igniter 62 simultaneously, and air mixture is lighted, and starts combustion furnace pointFire. Now, take wind hole 59, annular passage air intake out of by crater blast pipe 56, the one's intention as revealed in what one says that fires band 58, the one's intention as revealed in what one says that fires respectivelyPipe 33, annular passage divide airduct 36, outer ring air channel 40, interior annular passage 41, straight airduct 37, straight airduct side air-out hole 39,Curved airduct 42, curved airduct side air-out hole 43, leeward band blast pipe 31, leeward band 10, leeward band exhaust vent 11, spiral duct enterAir port 20, spiral duct 17, spiral exhaust vent 44 are simultaneously to burner hearth air blast. Then by Timer Controlling igniter 62, igniting combustionAir valve 51, some windburn band valve 53, leeward band valve 30 are closed, and combustion furnace enters normal operating conditions.
Combustion furnace enters after normal operating conditions, regulates firepower large by annular passage valve 34, crater air intake valve 57Little. Straight airduct 37 to burner hearth air blast process in, although multiple straight airduct side air-outs hole 39 air-out directions and straight airduct 37 axisVertically, but due to the barrier effect of fuel to wind, air blast direction is likely by the change of fuel, and straight airduct cap 38 can be kept watchTo again correcting, within certain areal extent, keep horizontal direction to disperse equably air blast，Straight airduct cap 38 also has and stops itTop dust enters the effect in straight airduct 37.
Through after a period of time, burner hearth fuel height reduces, and material level tablet 64 declines, and material level inductor 54 resets,Again start feeding mechanism to burner hearth charging, so repeat above fill process, make combustion furnace reach the object of continuous operation.
While banking up a fire, cover fire banking-up board 65, close all air intake valves, open B chip removal valve 16, ash discharge valve 28, startScrape grey motor 2, vibrator 35, in burner hearth, dust arrives ash discharge gear 32 places by vibration sieve aperture 47, then by ash discharge gear 32Spoke discharge out of the furnace after dust is scraped to ash releasing tube 27; Dust in spiral duct 17 and bits shape thing are by B chip removal mouth simultaneously15 discharge out of the furnace.
