Description
Technical field
The utility model belongs to boiler technology field, is specifically related to the two combustion steam boiler of a kind of new and effective living beings.
Background technology
Biomass energy is that solar energy is stored in living beings with the form of chemical energy by photosynthesis by plant, biomass energy is the fourth-largest energy being only second to coal, oil and natural gas at present, be a kind of regenerative resource, kind is many, distribution is wide, generally include timber and forest industry discarded object, agricultural wastes, water plant, oilseed plant, animal wastes, city and industrial organic wastes etc., living beings are a kind of clean fuels, and sulfur content is low; In living beings, ash content is general also very little, so the smoke content after Thorough combustion is very low.Biomass fuel combustion process has the feature of carbon dioxide zero discharge, and this has special meaning for day by day serious " greenhouse effects " of alleviation.
At present, the combustion technology of biomass boiler, product is CFBB and station boiler mostly, and total installation of generating capacity is no more than 10000MW.And mostly to there is on slagging scorification, reciprocal grate the problems such as fuel density is uneven, and cloth wind is uneven, efficiency of combustion is low, it is high to add biomass solid particle processing cost, and logistics cost is high.Like this, just create biomass boiler operating cost higher than coal-burning boiler, make user be difficult to accept.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of discharge NO
xand SO
xlower than coal-burning boiler, the two combustion steam boiler of the living beings that environment protecting is good.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises body of heater, the first combustion chamber is provided with in body of heater, it is characterized in that: the first side, combustion chamber is provided with the first feed bin, the first feed bin is by helixes feed equipment and fuel injection burner and first combustion chamber with an air-supply arrangement; Be provided with lower aditus laryngis below first combustion chamber, be provided with grate firing room below lower aditus laryngis, grate firing is provided with reciprocal grate below room, and side, grate firing room is provided with the second feed bin; The rear side of the first combustion chamber is provided with the second combustion chamber, and the front side of the first combustion chamber is provided with the 3rd combustion chamber; The top of the first combustion chamber is provided with superior laryngeal aperture, and top and second combustion chamber of superior laryngeal aperture are passed through in the first combustion chamber, and the second combustion chamber is connected with the flank flue of first left and right sides, combustion chamber; Flank flue is connected with the 3rd combustion chamber on front side of described first combustion chamber; The exhaust opening on heat exchanger and body of heater is provided with on front side of 3rd combustion chamber.
As a kind of preferred version of the present utility model, between described exhaust opening and heat exchanger, be provided with economizer.
As another kind of preferred version of the present utility model, described reciprocal grate is water-cooling reciprocation stove grate.
The beneficial effects of the utility model: 1, the utility model is by grate firing Indoor Combustion particulate biomass fuel above reciprocal grate, thus provide burning condition for the powdery biomass fuel in the first combustion chamber and/or living beings pulpous state fuel; It is uneven that this combustion system solves biomass fuel easy density on fire grate, and cloth wind is uneven, and impact is burnt, and when room is fired, biomass ash viscosity is large, the problem of easy slagging scorification, deslagging difficulty.
2, the utility model arranges reciprocal grate, and it has two kinds of effects: one is that biomass granule fuel grey shell after Volatile wraps carbon, and be difficult to after-flame, pulling by reciprocal grate, can remove grey shell, by the fixed carbon thermal release of the inside out.Two is sent into by flame in the first combustion chamber, by the powdery biomass fuel in the first combustion chamber and/or living beings pulpous state ignited fuel.
3, fuel sprays in the first combustion chamber by fuel injection burner by the utility model, under the effect of an air-supply arrangement, spray into powdery biomass fuel in the first combustion chamber and/or living beings pulpous state fuel and the abundant mixed combustion of air, form diffusivity flame, due to the design feature of lower aditus laryngis and grate firing room, actual flame front containing too much air, therefore, can not increase O
2, thus decrease NO
xgeneration, reach the object of environmental emission reduction.
4, the utility model is by arranging flank flue and the 3rd combustion chamber, flue gas can be made to amplify in the 3rd combustion chamber, spread and current stabilization, sends outside stove after flue dust is degraded through heat exchanger and economizer.
