Embodiment
The embodiment and the course of work of the present invention are further described below in conjunction with the accompanying drawings.
The orientation such as upper, lower, left, right, front and rear in present specification term be based on position relationship shown in the drawings and
Establish.Accompanying drawing is different, then corresponding position relationship is also possible to change therewith, therefore can not be interpreted as with this to protecting model
The restriction enclosed.
As shown in figure 1, a kind of hot-blast stove, including feeding warehouse 1, vaporizer 2, combustion chamber 3, secondary furnace 4, wind mixed chamber 5, fire grate
6th, separator 10, back-end ductwork 11 and water sealed tank 9 etc..
Feeding warehouse 1 is arranged on the fuel such as the top of vaporizer 2, biomass and feeds vaporizer 2 from feeding warehouse 1, in vaporizer 2
Interior to gasify, caused gasification gas enters combustion chamber 3 by the connection flue 18 being connected with combustion chamber 3.Vaporizer 2, burning
Horizontal alignment arranges that to form Multi-stage reciprocal formula material pneumatic passage extends the reaction time successively for room 3, secondary furnace 4 and wind mixed chamber 5.Gas
Solid residue after change falls into the fire grate 6 for being arranged on vaporizer 2, connection flue 18 and the bottom of combustion chamber 3.Fire grate 6 is positioned at gasification
The bottom end of room 2 is provided with pusher 19 so that forms impetus between the fire grate segment on fire grate 6.The bottom of fire grate 6 is provided with
Air compartment 7, classification are passed through First air, and both supply vaporizer 2 in part was used as gasifying agent, also as gas and the residue of gasifying after gasification
Combustion adjuvant.Residue moves under the promotion of fire grate 6 toward slag mouth 13, and slag mouth 13 is located at the end of fire grate 6, positioned at the He of combustion chamber 3
The bottom of secondary furnace 4.Fire grate 6 is in tilted layout from the one end of vaporizer 2 to the one end of slag mouth 13.It is anti-with First air in residue moving process
