Specific embodiment
A specific embodiment of the invention and the course of work are further described with reference to the accompanying drawing.
The positional terms such as the upper, lower, left, right, front and rear in present specification be positional relationship based on the figure and It establishes.Attached drawing is different, then corresponding positional relationship is also possible to change therewith, therefore cannot be interpreted as with this to protection model The restriction enclosed.
As shown in Figure 1, a kind of gasified combustion apparatus, including vaporizer, feeding device 1 and combustion chamber 7.
Feeding device 1 is arranged at the top of vaporizer.To prevent gasification gas leakage, feeding device 1 selects two-stage sealing charging Device.Feeding device includes the feed pipe below hopper and setting hopper, two-stage inlet valve is arranged in feed pipe, to prevent fuel It blocks, setting gauge can be set in pipe.
Vaporizer and combustion chamber 7 arrange that lower part is equipped with drainage channel and is connected to vaporizer with combustion chamber 7 in horizontal alignment. Vaporizer and 7 bottom of combustion chamber are provided with fire grate, and the drainage channel between vaporizer and combustion chamber 7 is arranged on fire grate top, And material channel is formed on fire grate top.The setting of drainage channel dipping type, vaporizer side is high and 7 side of combustion chamber is low.
Gasification zone 2 and guiding area 3 that vaporizer is divided into horizontal alignment by arch wall 4 are provided in vaporizer, and guiding area 3 is set It sets between gasification zone 2 and combustion chamber 7.As shown in Fig. 2, 4 bottom of arch wall is arch, it is equipped at intervals with several hollow panes thereon, Gasification zone 2 is connected to guiding area 3.Arch wall 4 selects fire resisting brick masonry.
2 lower part of gasification zone is provided with several gasifying agent pipes 12.Gasifying agent pipe 12 can two rows setting up and down.In gasifying agent pipe 12 It is passed through gasifying agent, such as air, vapor.Vaporizer inner wall lays refractory material, makes to form accumulation of heat gasification in vaporizer.
Make any or a variety of mixed patch fuel or biology including lumped coal, moulded coal and blocky biomass Matter bulk cargo enters vaporizer from feeding device 1, falls on the fire grate below vaporizer, and gradually fills the gasification of vaporizer Area.Gasification zone fuel is full of or is partly full of.Patch fuel filled in gasification zone can guarantee to have certain gap to Can smoothly it gasify.
Starter operation.It is passed through gasifying agent from gasifying agent pipe 12 after igniting, makes fuel and gasifying agent that gasification reaction occur, Generate gasification gas and residue after gasifying.Gasifying agent also plays loosening to fuel simultaneously.
The gasification gas and a small amount of residue after gasifying (including the fuel not being gasified totally) generated in vaporizer enters from arch wall 4 leads Draw area 3.A small amount of residue after gasifying into guiding area 3 is fallen on fire grate, and gasification gas is flowed along material channel to combustion chamber 7.
Fire grate includes gasification fire grate 5 and burn-out grate 6, and the setting of burn-out grate 6 is in gasification 5 end of fire grate and is in staged cloth It sets.Gasification fire grate 5 and burn-out grate 6 are located at 7 bottom of vaporizer and combustion chamber, and tilt towards 6 end of burn-out grate Arrangement.Gasification fire grate 5 and 6 bottom of burn-out grate are respectively arranged with gasification grate wind chamber 10 and burn-out grate air compartment 11.
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 10, start-up course The fuel not being gasified totally and residue after gasifying in unvaporized fuel and normal course of operation is in the moving process on fire grate 5 that gasifies In, further gasify, continues to generate gasification gas and residue after gasifying.Residue after gasifying is carried out on gasification fire grate to gasification fire grate 5 End is fallen 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 falling It is stirred during falling.Burn-out grate air compartment 11 is passed through air as oxidant, so that residue after gasifying gradually burns.
6 end of burn-out grate is provided with slag channel 8, and 8 bottom of slag channel is provided with water sealed tank 9.Residue after burning It falls in water sealed tank 9 and is embathed and cooled down.
It is provided with several overfiren air ports 13 at 7 bottom inlet of combustion chamber, is passed through air as oxidant.Gasification gas passes through object Material channel enters combustion chamber 7 from the entrance of 7 bottom of combustion chamber and burns, and the high-temperature flue gas for generation of burning passes through 7 top of combustion chamber Outlet enters subsequent residual heat using device.
For the nitrogen oxides that removing combustion process generates, 7 lower part of combustion chamber is equipped with SNCR access port 14, sprays into urea or ammonia The denitrfying agents such as water.
The present invention is suitable for the granular bulk cargo of patch fuel or greater particle size, has gap between fuel, so that gasifying agent It can be passed through and smoothly gasify.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
