Operation principle:
Time initial, all valves are in closed condition, and combustion furnace is in the state of banking up a fire.
When starting combustion furnace, start power supply and gearbox 4, open A chip removal mouth valve 22, the output 5 of gearbox A drives flat spin 7 to rotate, fuel enters horizontal feed pipe 9 from funnel 1, by flat spin 7, fuel is delivered to vertical feed pipe 23, through burner hearth feed pipe 45, fuel is sent into burner hearth by vertical spin 26 again, when burner hearth fuel height reaches material level tablet 64 position, material level tablet 64 is by fuel jack-up, by material level induction rod 55, material level inductor 54 is started to control, feeding mechanism is out of service.
In fill process, bits shape thing in fuel falls between the upper surface of chip removal web plate 24 and vertical spin bearing 18 by chip area 12 or the inclined-plane of chip removal mesh 25 or vertical spin 26 or the gap of vertical spin 26 and vertical feed pipe 23, discharges 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 reduced when burning and Mars ash.
Open fire banking-up board 65, igniting burnt gas valve 51, some windburn band valve 53, crater air intake valve 57, annular passage valve 34, lower air duct valve 30, spiral duct valve 19, take air holes 63 out of by a some windburn band 61, some windburn after igniting combustion gas and air mixing and arrive upper furnace 49 inside, initial igniter 62 simultaneously, air mixture is lighted, and starts combustion furnace ignition.Now, take air holes 59 out of respectively 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, annular passage blast pipe 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 air inlet 20, spiral duct 17, spiral exhaust vent 44 simultaneously to burner hearth air blast.Then closed by Timer Controlling igniter 62, igniting burnt gas valve 51, some windburn band valve 53, leeward band valve 30, combustion furnace enters normal operating conditions.
After combustion furnace enters normal operating conditions, regulate firepower size by annular passage valve 34, crater air intake valve 57.In straight airduct 37 pairs of burner hearth aeration step, although multiple straight airduct side air-out holes 39 air-out direction and straight airduct 37 axes normal, but because fuel is to the barrier effect of wind, air blast direction is likely by the change of fuel, and straight airduct cap 38 can be corrected wind direction again, within certain areal extent, horizontal direction is kept to disperse air blast equably
,straight airduct cap 38 also has and stops dust above it to enter the effect in straight airduct 37.
Through after a period of time, burner hearth fuel height reduction, material level tablet 64 declines, and material level inductor 54 resets, and again starts feeding mechanism to burner hearth charging, so repeats above fill process, make combustion furnace reach the object of continuous operation.
When 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, start and scrape grey motor 2, vibrator 35, in burner hearth, dust arrives ash discharge gear 32 place by vibration sieve aperture 47, then discharges out of the furnace after dust being scraped ash releasing tube 27 by the spoke of ash discharge gear 32; Dust simultaneously in spiral duct 17 and bits shape thing are discharged out of the furnace by B chip removal mouth 15.
Finally close B chip removal valve 16, A chip removal mouth valve 22, ash discharge valve 28 and power supply.
