The below of body of heater 1 is connected with cinder tank 12, it is outside equipped with cooling water tank 13, vaporized chemical import 14 is arranged on the cinder tank 12, so-called vaporized chemical is meant the mixed gas of air or air and water vapour, lime-ash outlet 15 is arranged at cinder tank 12 bottoms, and lime-ash outlet 15 connects with spiral slag off apparatus 17 and controlled by valve 16.
This producer is operation like this and operation:
Before the igniting preliminary stalk ash is dropped in the stove the about 50cm of floor height by inspection port 6.Then kindling material is dropped on the ash bed from inspection port 6; Solid biomass after giving processing is pushed in the burner hearth by feed auger 11; Start gas blower vaporized chemical (air is or/and the gas mixture of water vapour) is blasted burner hearth, lower floor's biological particles initial burning burning, and heating furnace body and upper materials, body of heater is again with the spiral heat exchange tube 4 in the part heat transferred flame retardant coating 3; The control oxygen-supplying amount gasifies biomass under the insufficient condition of oxygen supply, produce inflammable gas, and inflammable gas is purified the back and supplied with the user by air outlet 5 input gas-purification systems.
Solid biomass generates lime-ash at last through super-dry, restoring transformation, oxidation from top to bottom.The inflammable gas that the igniting initial stage produces is based on CO, after treating that furnace body temperature raises, the water vapour that is produced by spiral heat exchange tube 4 is able to preheating when going into ash bed through cinder tank 12, grate 18 are laggard successively with air mixed, improved gasification agent temperature, reduced cindery temperature simultaneously, in oxidation, reduction reaction, water vapour and CO
2Metallic element katalysis down conversions such as silicon, iron, aluminium are H in lime-ash
2And CH
4, make inflammable gas improve calorific value and quality.
Lime-ash after the gasification, the grate 18 that is rotated are radially passed and are fallen into cinder tank 12; Cinder tank 12 peripheral hardware cooling water tanks 13 are used to reclaim the lime-ash waste heat, gained hot water supply spiral heat exchange tube 4; Cooled lime-ash is discharged by valve 16, slag tapping equipment 17.
This producer is compared with conventional device, and following advantage is arranged: in (1) raw material input stove, be covered with furnace profile under the effect of refining rake 7, and rolled, improved density and rate of heat transfer.Material drying, restoring transformation, is oxidized to lime-ash in folding process.(2) Xuan Zhuan taper type grate 18 can continuously be removed lime-ash, thereby has guaranteed the stability of gasification bed, helps improving the continuity of combustion gas quality and production.(3) UTILIZATION OF VESIDUAL HEAT IN and CO to greatest extent
2The conversion inflammable gas is another characteristics of this vapourizing furnace.Utilize body of heater inner member and lime-ash waste heat to improve gasification temperature, thereby improved the zone of oxidation temperature, strengthened gasification intensity, improved material gasification rate and combustion gas quality; Cooling body of heater and the water vapour that produces participates in reaction, in lime-ash under the katalysis of metallic element, the CO that gasification is generated
2Be transformed into H
2, CH
