First by utilizing special equipment to be processed into granular biomass solid fuel, be added to feed bin 1, after fuel enters in windmill type one-level charger 2, by motor, rotate fuel is delivered in helical form secondary charger 4, helical form secondary charger 4 utilizes motor 3 to drive, and rotation is delivered to fuel in stove and burnt.The rotating speed of described windmill type one-level charger 2 is less than helical form secondary feeding machine 4, windmill type one-level feeding machine 2 is that clearance-type rotates, helical form secondary feeding machine 4 is in continuous rotation, because windmill type one-level feeding machine 2 is gap-like runnings, in 2 outlets of one-level charger and secondary charger 4 import upper spaces, there is no fuel, between the windmill shell inner face of described windmill type one-level feeding machine 2 and air vane, have all the time that a pair of the blade as symmetric points contacts take axle center, between windmill type one-level feeding machine 2 entrances and lower part outlet all the time in blockage, this is to occur once phenomenons such as power failures in order to prevent, the porch that flue gas rises to windmill type one-level charger 2 along helical form secondary charger 4 is the flue gas operation room that permeates then.Helical form secondary charger 4 is by the charge door arranging on boiler, fuel is delivered to burner hearth 16, the igniter 7 that is arranged on charge door bottom is lighted fuel, for fuel is fully burned, from matching air box 6a, utilize flexible pipe to be connected with igniter 7, after ignited fuel, send into some wind, increased inner oxygen content, fuel can strengthen the intensity of a fire.In addition, moving grate 10 is provided with air distribution path 10 a below, matching air box 6a utilizes ventilation duct to be connected with air distribution path 10, described fire grate consists of step-like refractory material, described sliding movable fire grate has plural blowhole 10b at least towards the direction of maintenance door, other one end of moving grate is connected with the pull bar of push-and-pull motor, in stove, near maintenance door position, be provided with helical form mucking machine 11, when moving grate 10 is pushed out, can by be arranged on moving grate 10 below the ashes on a step shift onto near the ditch arranging mucking machine 11, the wind that the blowhole 10b that moving grate 10 ends arrange can utilize blowhole 10b to blow out, ashes after burning are blown in the ditch being formed by refractory material near of helical form mucking machine 11, meanwhile, the fuel that utilizes secondary charger 2 to send to, first deliver on a refractory slab step above of moving grate 10, when piling with after fuel on upper level refractory slab, will fall on moving grate 10, along with the round push-and-pull of moving grate, the fuel of piling up on moving grate 10 is spread out, fuel is fully burned, fuel area can be strengthened.In stove on charge door, upper end is at least provided with two ajutages 24, between this ajutage 24 and matching air box 5a, utilizes flexible pipe to be connected, and in air-supply rear hearth, can obtain a large amount of oxygen, can add the large-scale combustion intensity of a fire.Described body of heater 18 has skin and internal layer, water is housed between ectonexine, in the water jacket of top, be also provided with the fire tube 21 through water jacket, in fire tube 21 bottoms with there is middle water jacket 19a, described burner hearth is around by refractory slab 23, 23a has formed one end and has offered the rectangular-shaped burner hearth 16 of exhanst gas outlet, towards the direction of maintenance door 12, it is pyrotechnics outlet, between burner hearth 16 top refractory slabs and middle water jacket 19a, be provided with center-aisle 16a, refractory slab is not set, that is to say that burner hearth 16 refractory slabs are pyrotechnics outlet at the rightabout of feeding machine, refractory slab 23 around flame in burner hearth has heated, it is the volatile combustion in the flue gas of completing combustion to what pass through center-aisle 16a that refractory slab relies on heat radiation meeting, meanwhile, middle water jacket 19a is heated, the flue gas of discharging from outlet flue 20 is like this colourless or white shape, reduced widely the pollution of flue gas to environment, to improving air quality, there is very large effect.Through center-aisle 16a flue gas out, there is a large amount of heats, when rising to water jacket bottom, flue gas has after the first return combustion chamber 22a forming between shorter fire tube 21 and body of heater 18 internal layers, turn back 90 °, along fire tube 21, be passed to by the second return combustion chamber 22b forming between in other one end of fire tube 21 and body of heater 18, flue gas is turned back after 180 ° and is again entered in the fire tube of top at the second return combustion chamber 22b, and the water in heating water jacket, finally discharges from outlet flue.Described the first return combustion chamber 22a and the second return combustion chamber 22b are interior except flue gas circulating direction is changed, can also heat body of heater 18 internal layers and the outer interior water of water jacket 19 forming, therefore, this boiler, compared with general boiler, has heating and the feature fast, efficiency is high.In addition, after boiler, be provided with lower maintenance door 12, shoot door 15, on maintenance door 12 and shoot door 15, be provided with lower knocker 14a, upper doorway 14b, at body of heater top, be provided with delivery port 17, the bottom of body of heater, be provided with water inlet 8, side is also provided with lower deashing hole 9a, front upper is provided with cleaning door 9b.
The beneficial effect that the movable furnace grate of this biomass burning granular fuel has is: stalk, wood residues and house refuse etc. can be turned waste into wealth, can make full combustion of fuel, the discharge of the harmful substances such as the carbon dioxide reducing, can reduce environmental pollution, improves and controls quality.
