Each composition parts of the invention are conventional products.
The principle and the course of work of the present invention is as follows：
Biomass granule fuel is added in hopper 2, covers hopper lid 1, blanking motor 30 drives blanking driving bent
Handle connecting rod 32 drives blanking dividing plate 3 to drop back to blanking driving crank connecting link 32 and contacted with blanking travel switch 28, and blanking stroke is opened
28 closures are closed, blanking motor 30 is stopped, and granular fuel falls to blanking dividing plate 3 through hopper 2 and the space of blanking dividing plate 3
Front space, blanking travel switch 28 flick under integrated control panel control, and blanking motor 30 drives blanking dividing plate 3 forward
Motion, fuel is promoted to drop on moving grate 19 by several times；Igniter 20 is opened, and igniting blower fan 27 blows the caloric value of igniter 20
To the fuel region of moving grate 19, igniter 20 is closed after fuel fire and completes to light a fire；Fire grate motor 24 drives stove
Row's driving crank connecting link 23 drives moving grate 19 to move back and forth, and fuel is progressively pushed into activity under the stop of rear side inboard wall of burner hearth 9
The front end of fire grate 19, then fall to fixed grate 18 and burn away, the anterior extension riser of moving grate 19 constantly promotes stationary furnace
Forward, last ash content is fallen in ash bucket 21 fuel through falling ash door 16 on row 18, the effect of fire grate travel switch 25 and blanking stroke
It is similar to switch 28；First air is sent into equipment box 29 through primary air fan 26, and then the combustion chamber 37 through being connected with equipment box 29 is delivered to
Fuel region；Secondary Air is sent into Secondary Air chamber by overfire air fan 31 through secondary air channel 4, then enters from secondary air hole on burner hearth 17
Burnt with the combustible component in flue gas in portion；Flue gas fully after burning enters flue 11 from the top of burner hearth 17, heating circulation water from
Flowed out after the flue gas heat exchange that water inlet pipe 34 enters in water-cooling wall 10, with flue 11 from outlet pipe 33, flue gas temperature in flue 11
Gradually reduce, the area of three smokejack 11 is gradually reduced reduces the volume-diminished feature brought to adapt to flue-gas temperature, ensure that cigarette
Gas velocity of liquid assets, augmentation of heat transfer；Low-temperature flue gas after heat exchange exits into smoke exhaust pipe 12 from the outlet of flue 11, then by whirlwind
Deduster 15 filters the bulky grain thing in flue gas, then filters fine particle by sack cleaner 14, by the row of smoke exhaust fan 13
Go out；Before terminating operation, blanking dividing plate 3 is first set to run to front end, it is in closed state to make the bottom of hopper 2, is then shut off blanking drive
Dynamic motor 30, when the reciprocating action of moving grate 19 causes fuel after-flame on moving grate 19 and fixed grate 18 several times, close
Fire grate motor 24, closes primary air fan 26 and overfire air fan 37, and flue gas closes smoke exhaust fan 13 after draining, finally pulls out ash
