Abstract
The utility model relates to a biomass double-layered furnace arch heat insulation hearth, which is characterized in that the heat insulation hearth comprises a feeding opening and a non-leakage fire grate connected with a feeding opening conveying device, a lower arch is disposed on the feeding opening, and an upper arch, a secondary tuyere mounted on the upper arch and a heat-concentration reburning opening connected with the upper arch are arranged on the lower arch. By aid of the heat insulation hearth, biomass fuel is burnt in a heat insulation environment, thereby increasing burning temperature inside the hearth, greatly increasing burning speed, and ensuring biomass to be sufficiently burnt inside the hearth. In addition, fuel burning efficiency is increased by more than 97%.
Description
Technical field
The utility model relates to a kind of boiler, relates in particular to a kind of boiler that is suitable for biomass burning especially
Burner hearth.
Background technology
Original biomass boiler is because of flue gas is short at residing time in furnace, Xiao Yi is floating for ash content severe, if do not take measures to cause shortcoming such as over-emitting black exhaust, therefore, this kind combustion system also is unfavorable for the burning of living beings.
Summary of the invention
The utility model main purpose is: solve the existing in prior technology deficiency, a kind ofly can improve biomass combustion efficient thereby develop, guarantee the not double-deck chimney arch adiabatic furnace of living beings of over-emitting black exhaust of biomass boiler.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the double-deck chimney arch adiabatic furnace of a kind of living beings, it is characterized in that: adiabatic furnace comprises charging aperture, the not runout row who links to each other with the charging aperture conveyer, arch is down arranged above the charging aperture, above the following arch overfiren air port that arches up and be installed in arch is arranged, and mouth is fired in the heat build-up that links to each other with arch again.
The beneficial effects of the utility model are: adopt adiabatic furnace, biomass fuel burns under adiabatic environment, has improved burner hearth internal combustion temperature and has greatly improved burning velocity, guarantees that living beings are fully burned in burner hearth.Owing to adopted the adiabatic combustion technology, burner hearth internal combustion temperature improves, and living beings are fully burnt, the contained combustible of furnace outlet flue gas reduces, the utilization rate of fuel improves, and has solved living beings and has burnt problem of difficult, complete, the no black smoke discharging of burning when having realized biomass combustion.Fuel economy improves more than 97%.Can the burn living beings of moisture about 40%.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Description of reference numerals: 1, charging aperture, 2 times arches, 3, heat build-up fires mouth again, 4, overfiren air port, arch 5, runout row 6.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
As seen from Figure 1: after fuel enters burner hearth by feeding system, by arch 5, encircle 2 down, furnace wall and runout row 6 adiabatic furnace internal combustion of forming not, no heating surface in the burner hearth, so the ignition temperature raising of fuel in burner hearth help further burning of biomass fuel.Arch is provided with overfiren air port 4 and heat build-up on 5 and fires mouthfuls 3 again in burner hearth.Secondary wind is arranged in the appropriate location in burner hearth, rotate flue gas flow field in the burner hearth that forms by wind and the acting in conjunction of secondary wind next time of wind of feeding, fire grate, flue gas is mixed strongly, promptly having prolonged flue gas flow makes flammable volatile matter fully burn again, prolong the burning time of soot particle simultaneously, thereby reached the purpose that improves fuel economy.
Claims (1)
1. the double-deck chimney arch adiabatic furnace of living beings, it is characterized in that: adiabatic furnace comprises charging aperture (1), the not runout row (6) who links to each other with the charging aperture conveyer, arch (2) is down arranged above the charging aperture, above the following arch arch (5) is arranged and be installed in the overfiren air port (4) of arch, and mouth (3) is fired in the heat build-up that links to each other with arch again.
