Change 5 end of fire grate and be in stagger, 6 end of burn-out grate is provided with slag channel.Gasification fire grate 5 and burn-out grate 6 divide
Not Wei Yu vaporizer and burning and UTILIZATION OF VESIDUAL HEAT IN component bottom, and tilt down arrangement towards 6 end of burn-out grate.Gasification furnace
Row 5 and 6 bottom of burn-out grate are respectively arranged with gasification grate wind chamber 7 and burn-out grate air compartment 8.
Make any or a variety of mixed including the bulks such as lumped coal, moulded coal and wood chip or bark/sheet biomass
The bulk of conjunction/sheet fuel enters vaporizer 2 from feeder 1, falls on the fire grate below vaporizer 2, and gradually fill gas
Change the gasification zone of room 2.Gasification zone fuel is full of or is partly full of.Patch fuel is filled in gasification zone can guarantee have centainly
Gap so as to smoothly gasifying.
It is passed through gasifying agent from gasifying agent pipe 13, makes fuel and gasifying agent that gasification reaction occur, gasification gas is generated and gasifies residual
Slag.Gasifying agent also plays loosening to fuel simultaneously.
Gasification fire grate 5 and 6 front end of burn-out grate are equipped with material-pulling device, can independently regulate and control pusher speed.Fuel is gasifying
It is mobile towards the direction of burn-out grate 6 on fire grate 5.Air is passed through as gasifying agent from gasification grate wind chamber 7, and start-up course is not
The fuel not being gasified totally and residue after gasifying in vaporising fuel and normal course of operation during gasifying mobile on fire grate 5,
Further gasification continues to generate gasification gas and residue after gasifying.Residue after gasifying is carried out on gasification fire grate 5 to 5 end of gasification fire grate
End, falls when on burn-out grate 6, and because of the staged setting between gasification fire grate 5 and burn-out grate 6, residue after gasifying is being fallen
It is stirred in the process.Burn-out grate air compartment 8 is passed through air as oxidant, so that residue after gasifying gradually burns.
It is provided with connection furnace wall between vaporizer 2 and secondary furnace 3, it is logical to connect formation material between furnace wall and the fire grate of lower part
Road, the gas that gasifies flow to secondary furnace 3 along material channel.Rear arch 16 is formed at the top of 4 bottom of back-end ductwork and fire grate, rear arch 16 is located at
6 top of burn-out grate.Combustion chamber, combustion chamber setting are formed between rear arch 16 and stepped fire grate, connection furnace wall and 3 entrance of secondary furnace
Several secondary air channels.The vertical section and rear arch 16 and stepped fire grate being distributed between vaporizer guiding area 3 and stepped fire grate
Between horizontal section on.3 inlet of secondary furnace is provided with several after-flame air hoses 14.Secondary air channel and after-flame air hose 14 spray respectively
Enter Secondary Air and burnout degree, fractional combustion is formed to gasification gas.Meanwhile the Secondary Air sprayed into close to the secondary air channel of stepped fire grate
Also it will promote the burning of residue after gasifying.
The top of secondary furnace 3 and back-end ductwork 4 is provided with drum 10.3 top of secondary furnace is provided with superheater 11, tail portion cigarette
It is provided with the convection bank 12 of vertical in road 4, heat recovery is carried out to the high-temperature flue gas for entering back-end ductwork 4.Superheater
11 are connect by header with drum 10.Convection bank 12 is by header and/or directly connect with drum 10.
When being provided with top flue between secondary furnace 3 and back-end ductwork 4, secondary furnace 3 is set before exporting to convection bank 12
It is equipped with drainage plate 19, drainage plate 19 selects spiral type drainage plate namely spiral type deflector.19 center line of drainage plate in horizontal or
Person makes the high-temperature flue gas that carry particle flow to convection bank 12 along spiral type drainage plate from secondary furnace 3 close to being horizontally disposed with.
As shown in Figure 1, be disposed with deflector 18 on the outside of convection bank 12, deflector 18 select streamlined, spiral type or
Hyperbolic-type, so that high-temperature flue gas power-assisted is small, the coefficient of heat transfer is high between convection bank 12, enhances flue gas heat exchange absorption.And
And since the deflector 18 of streamlined, spiral type or hyperbolic-type is arranged, the particulate matter in flue gas is difficult to attached product in convection tube
On beam wall surface, acted on to reach from deashing.
Gasification gas passes sequentially through 4 quilt of secondary furnace 3 and back-end ductwork in the high-temperature flue gas that combustion chamber and the burning of secondary furnace 3 generate
Superheater 11 and vertical convection bank 18 are discharged after absorbing heat from the flue 15 of 4 lower part of back-end ductwork.
Ash tube is formed on 4 bottom of back-end ductwork.Slag bath 17 is protruded into ash tube and slag channel, and slag bath 17 uses water seal.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
