Description

A kind of biomass combustion fluidized bed furnace system

Technical field

This utility model belongs to technical field of new energies, concretely relates to a kind of biomass combustion fluidized bed furnace system。

Background technology

Existing fluidized bed furnace production line, raw material is when burning Indoor Combustion, the raw material of burning is sucked in burner hearth by air-introduced machine, factor because of raw material self gravitation, part material can fall to bottom of combustion chamber, produce substantial amounts of residue after using a period of time and overstock in bottom of combustion chamber so that suck the material combusting in burner hearth insufficient, cause combustion process produces substantial amounts of black smoke。

Summary of the invention

The purpose of this utility model is to provide a kind of biomass combustion fluidized bed furnace system, feed end at combustor arranges an aerator and No. two aerators, number wind, a wind direction for No. two wind combine with the wind direction of air-introduced machine, make the ceaselessly rotary burning be delivered in burner hearth in combustor of the raw material in combustor, combustion process falls to bottom of combustion chamber almost without raw material, make burning more abundant, black smoke under life-time service, will not be produced。

For solving above-mentioned technical problem, the purpose of this utility model is achieved in that a kind of biomass combustion fluidized bed furnace system, including dog-house, elevator, feed bin, fluidized bed furnace, fluidized bed furnace includes combustor, burner hearth and air-introduced machine, and raw material is delivered to feed bin by the boosted machine of dog-house, and the auger in feed bin is by feedstock transportation to combustor, combustion chamber burner hearth, the flue gas produced after material combusting is caused burner hearth, flue by combustor by air-introduced machine, and flue connects foam dust arrester

Combustor is provided with feed end, feed end connects feed bin, feed end is provided with an aerator, No. two aerators, a number air supplying part of a number aerator connects feed end and tilts to be delivered to feed end by wind, make a wind with clockwise/counterclockwise azimuthal rotational motion inside feed end, No. two air supplying part of No. two aerators connect feed end and tilt to be delivered to feed end by wind, make No. two wind with clockwise/counterclockwise azimuthal rotational motion inside feed end, at a wind after raw material entrance feed end, rotate-stationary mode is made under the effect of No. two wind and air-introduced machine, a number air supplying part and No. two air supplying part are not at the same side of feed end。

What this utility model was useful has the technical effect that the feed end at combustor arranges an aerator and No. two aerators, number wind, a wind direction for No. two wind combine with the wind direction of air-introduced machine, make the ceaselessly rotary burning be delivered in burner hearth in combustor of the raw material in combustor, combustion process falls to bottom of combustion chamber almost without raw material, make burning more abundant, black smoke under life-time service, will not be produced。

Detailed description of the invention

This utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-2；

A kind of biomass combustion fluidized bed furnace system, including dog-house, elevator, feed bin, fluidized bed furnace, fluidized bed furnace includes combustor, burner hearth and air-introduced machine, raw material is transported to dog-house by electric block, boosted machine is delivered to feed bin, and the auger in feed bin is by feedstock transportation to combustor, combustion chamber burner hearth, the flue gas produced after material combusting is caused burner hearth, flue by combustor by air-introduced machine, and flue connects foam dust arrester。

Combustor is provided with feed end, feed end connects feed bin, feed end is provided with an aerator, No. two aerators, a number air supplying part of a number aerator connects feed end and tilts to be delivered to feed end by wind, make a wind with clockwise/counterclockwise azimuthal rotational motion inside feed end, No. two air supplying part of No. two aerators connect feed end and tilt to be delivered to feed end by wind, make the rotary motion in a clockwise direction inside feed end of No. two wind, at a wind after raw material entrance feed end, ceaselessly make rotate-stationary mode under the effect of No. two wind and air-introduced machine and be delivered in burner hearth。

Wherein, an air supplying part and No. two air supplying part are not at the same side of feed end, as: an aerator is blown into feed end by the top of feed end, and No. two aerators are entered feed end by the sidewall air supply of feed end。

Wherein, an aerator, No. two aerators and air-introduced machine all have frequency conversion motor control。

Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model。
