Abstract
The invention discloses a biomass continuous gasification low-nitrogen combustion machine. Biomass gasification and combustion are carried out in the combustion machine, a traditional fixed fire grate is replaced with a water cooled fire grate, a rotary ash removing device and a spiral slag removing machine, and during ash and slag removing, combustion and gasification of fuel are not affected; and a gasification chamber is defined by a water cooled system and a steel plate in a welding manner, the combustion temperature in the gasification chamber can be decreased through the water cooled system, and generation of coking and NOx can be effectively avoided.
Description
Technical field
The present invention relates to a kind of living beings continuous gasification low nitrogen burning machine, belong to biomass gasification fired equipment technical field.
Background technology
Traditional biomass combustion machine, because ignition temperature is high, not only NO
xgrowing amount is large, and very easily coking, and in addition, due to reasons in structure, lime-ash cleaning interruption is carried out, necessary blowing out between clear-up period, thus causes combustor not run by continuous and stable.
Summary of the invention
The object of the invention is to solve above-mentioned Problems existing, a kind of living beings continuous gasification low nitrogen burning machine is provided, biomass combustion and gasification are carried out in stove, use water-cooled grate, revolution ash ejector and spiral-type slag eliminator to replace traditional fixed grate, when lime-ash is cleared up, do not affect burning and the gasification of fuel.The water-cooling system of vaporizer can reduce ignition temperature, effectively prevent coking and NO
xgenerate.
The present invention is achieved through the following technical solutions:
A kind of living beings continuous gasification low nitrogen burning machine, comprise water-cooling system, charging aperture, secondary air channel, water-cooled grate, ash exhauster, vaporizer, exhaust outlet, supporting seat, heat-insulation layer, described water-cooling system is made up of water outlet header, water inlet header, water cooling tube, band steel, water cooling tube runs through water outlet header and water inlet header be welded into entirety, and water cooling tube and band steel are welded into membrane wall; Described charging aperture is positioned at middle and lower part on the left of water-cooling system; Described secondary air channel is positioned at below charging aperture; Described water-cooled grate is welded by part water cooling tube and fire grate segment, is positioned at bottom water-cooling system; Described ash exhauster by turning round ash ejector, spiral tapping machine, steel plate, transmission device form, and is placed in below on the left of water-cooled grate; Described vaporizer is surrounded by water-cooling system, Plate Welding; Described heat-insulation layer is covered in water-cooling system outer surface.
Above-mentioned living beings continuous gasification environment-friendly stove, water cooling tube in water-cooled grate is tilting with angle [alpha], α=20 ° ~ 30 °, fire grate segment and water cooling tube angle are β angle, β=5 ° ~ 10 °, each fire grate segment forms gap, makes wind can blow to fuel and lime-ash of jetting downwards by gap, thus lime-ash is dropped on revolution ash ejector automatically discharged by spiral tapping machine;
Above-mentioned living beings continuous gasification low nitrogen burning machine, described revolution ash ejector, is formed by connecting through screw by axle a and rake teeth;
The present invention compared with prior art, has the following advantages: obviously reduce NO
xgrowing amount, slagging prevention, gasification of biomass is carried out by machine automatization continuously with burning continuous and stable, lime-ash cleaning.
