Abstract

The utility model relates to a novel biomass-briquette-fired organic heat carrier boiler, which is provided with a pipe-support-type body, a feeding system, a hearth, a fire grate, a gas flue and an air duct. The novel biomass-briquette-fired organic heat carrier boiler is characterized in that the feeding system adopts a tilting screw feeder, materials are fed in a sealed way, feeding air blows fuels, and not only can backfire be prevented, but also the fuels can be evenly spread onto the fire grate; a large-area scale-type fixed fire grate is adopted in the hearth, a tilting surface is cast at the front part of the fire grate and is connected with a feed inlet and material leakage can be reduced; a smoke eliminating and dust setting chamber is designed in a convection zone at the rear part of the hearth and the problem of producing black smoke is solved; and a secondary air spray nozzle of the air duct is arranged at the rear part of the hearth, and the secondary air spray nozzle, the feeding air and primary air form a proper aerodynamic field to promote the burning out of the fuels. The novel biomass-briquette-fired organic heat carrier boiler has the advantages that not only can the biomass briquette be efficiently burned, but also the environmental pollution can be reduced, and the boiler is low-carbon, environmentally-friendly and energy-saving and is fully compliant with the burning characteristics of the biomass briquette.

Description

Novel biomass shaped fuel organic heat carrier furnace
Technical field
The utility model relates to a kind of boiler, relates in particular to the organic heat carrier furnace of biomass burning shaped fuel.
Background technology
The boiler of organic heat carrier of prior art generally uses fuel oil, combustion gas or coal, and perhaps direct direct biomass burning shaped fuel on coal-burning boiler does not almost have special biological substance for combustion shaped fuel.The fuel applications scope that this has not only limited boiler of organic heat carrier has also caused boiler efficiency low, the problems such as waste fuel, over-emitting black exhaust.At present along with the oil supply crisis increasingly sharpens; the cry of environmental protection requirement is increasingly surging; as the biomass molding fuel with the environmental protection characteristic that compares favourably with fuel oil; its secondary industry is also just flourish, therefore designs a kind of special organic heat carrier furnace take biomass molding fuel as fuel extremely urgent.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, reduced investment, easy to operate novel biomass shaped fuel boiler of organic heat carrier.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of biomass molding fuel boiler of organic heat carrier, has the pipe-support type body, feeding system, burner hearth, fire grate, cigarette, air channel, it is characterized in that: feeding system adopts oblique spiral feeder, take to seal feed, charging aperture is provided with the feeding air port, with the moving fuel of feeding wind; Adopt large tracts of land flake type fixed grate in the burner hearth, described fire grate front portion is built the inclined plane and is linked to each other with charging aperture; Convective region, described burner hearth rear portion is designed to the smoke reducing dust lowering chamber, solves the problem of over-emitting black exhaust; The overfire air jet in described air channel is arranged in the burner hearth rear portion, consists of suitable aerodynamic field with feeding wind and a wind, increases the flue gas disturbance, promotes the after-flame of fuel.
The beneficial effects of the utility model are:
Adopt the spiral continuous uniform to advance hermetically feed, large tracts of land not to arrange the know-how measures such as overfire air jet in flake type fixed grate, design smoke reducing dust lowering chamber, convective region, the burner hearth rear portion of escape of fuel, guarantee biomass molding fuel smooth combustion and sufficient combustion in stove; Adopt the pipe-support type type of furnace, can the smooth combustion biomass molding fuel, again can meet the requirement of environmental protection, meet the burning feature of biomass molding fuel fully.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Description of reference numerals: 1-body, 2-screw(-type) feeder, 3-feeding air port, 4-burner hearth, 5-louver stoker, 6-primary air nozzle, 7-overfire air jet, 8-smoke reducing dust lowering chamber.
The specific embodiment
Below by embodiment also by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
A kind of biomass molding fuel boiler of organic heat carrier as shown in Figure 1, by pipe-support type body 1, screw(-type) feeder 2, burner hearth 4, smoke reducing dust lowering chamber 8, cigarette, air channel form.Fuel falls into feed pipe through screw(-type) feeder 2, is sent on the louver stoker 5 by feeding air port 3 usefulness feeding wind, and blowing of feeding wind can prevent that fuel is deposited in the front end of fire grate 5 and prevents tempering; The scale chain grate 5 that does not leak has improved the utilization rate of fuel.Overfire air jet 7 Secondary Air out, be arranged in the burner hearth rear portion, and form eddy flow by feeding air port 3 feeding wind and primary air nozzle 6 wind out out in lower furnace portion, increase the flue gas disturbance, the prolong smoke flow process is conducive to the after-flame of fuel in burner hearth more.Flue gas enters the convective region at burner hearth rear portion behind the radiation heating-surface of upper furnace, convective region is designed to the structure of smoke abatement and dust control, flue gas most of flying dust natural subsidence after half-turn is cleared out of boiler in the bottom of the dirt pocket 8 of bottom by the rear portion shoot door.fully burn through burner hearth and the dedusting of smoke reducing dust lowering chamber after, boiler not only efficient improves, and also reaches not the environmental requirements such as over-emitting black exhaust simultaneously.
