Abstract
The utility model discloses a biomass fixed bed gasification furnace, which comprises a shell, a furnace, a fire grate, an air inlet, an ash outlet, a coal gas outlet and a furnace cross section which is in a long strip shape or a rectangle or a square shape. Present gasification producer, furnace cross-section are circular, and air medium and living beings raw materials are difficult to the homogeneous mixing, can not maintain the stability of oxidation and reduction, and the highest gas production can only reach 600 ~ 700 cubic meter per hour, the utility model discloses furnace cross-section is rectangular shape, can produce gas in succession, and under the state that gasifier capacity reaches 1500 cubic meter per hour, the air still can with living beings intensive mixing.
Description
Technical field
The utility model relates to a kind of fixed-bed gasification furnace, a kind of biomass gasifying furnace of more specifically saying so.
Background technology
The main component of stalk is that carbon, hydrogen, oxygen etc. are elementary composition, stalk is pulverized through hay cutter, also can be as firewood, corn cob raw coal etc. without processing, directly enter vapourizing furnace, enter in the gasification producer by self-conveyor feed, redox reaction takes place in Controlled burning under anoxic condition, each element is reformulated inflammable gass such as carbon monoxide, hydrogen, methane by thermo-cracking, the realization energy is changed to gasiform by solid-state.But it all is to adopt the malleation air blast that stove is sent out in present gasification, can not continuously feeding, can only intermittent operation, and working efficiency is not high, and has residual gas to leak at kindling with when reinforced again, easy contaminate environment, and dangerous property.Simultaneously, vapourizing furnace all is a garden shape structure, section of burner hearth is garden shape, and the air of air inlet port sprays to the garden heart from perisporium, for biomass combustion provides oxygen, because the distance of spraying is limited, the vapourizing furnace of this structure runs into air dielectric and biomass material is difficult to mixed uniformly difficulty, can not keep oxidation and reductive stability, and high yield tolerance can only reach 600～700 cubic metres/hour, it is big to be not suitable for air demand, and the occasion of air feed is used continuously.
Summary of the invention
The purpose of this utility model provides the vapourizing furnace that a kind of section of burner hearth is a long strip shape, and the capacity of aerogenesis, and vapourizing furnace continuously reaches under 1500 cubic metres/hour the state, air still can with the biomass thorough mixing.
The technical solution of the utility model is as follows:
Biomass fixed-bed gasification furnace includes housing, burner hearth, and fire grate, air inlet port, ash output hole, gas exit is characterized in that the burner hearth transverse section is long strip shape or rectangle or square.
The outer housing of burner hearth is an air jacket, and transom window is arranged on the housing, is distributed with air inlet port on the burner hearth, and air inlet port links to each other with transom window.
The spacing of air inlet port is between 160～300mm.
Fire grate is made up of fixedly grate and movable grate, and movable grate is installed in the fixedly below of grate by rotating shaft, the fire bars of movable grate and fixedly the firebar spacing of grate arrange.
Housing top is provided with muff.
Movable grate and fixedly grate and fire bars cross section are the water droplet shape.
Long strip shape of the present utility model, rectangle furnace cross section, the air of air inlet port sprays to burner hearth central vertical face from perisporium, and in theory, no matter burner hearth how long, air dielectric and biomass material can both uniform mixing, solved the uniform mixing difficult problem of air and biomass in the large vol fixed-bed type biomass gasifying furnace, vapourizing furnace can be worked under negative pressure state simultaneously, gas leakage can not take place, guaranteed production safety, the realization serialization is produced, and the air feed single-machine capacity increases, and unit cost reduces.
It is raw material that the utility model can adopt stalk, corn cob etc., is based on utilizing agricultural resource, can be widely used in the central heating or the hot water service of rural area or small town citizen, also can be used for vegetables in greenhouse booth plantation, breed in winter etc.
