Abstract
A secondary air distributor for a biomass direct combustion furnace relates to a biomass stove and is arranged above a boiler. The secondary air distributor comprises a hollow cavity formed by enclosing an inner wall, an outer wall, an upper wall and a bottom wall, wherein the middle part is provided with a fire hole; an air inlet is arranged on the outer wall; a first air outlet is arranged on the inner wall; and a second air outlet is arranged on the bottom wall in order to fully combust the secondary air for compensating combustion by rotating the air. The secondary air distributor of the invention has simple structure, is characterized by easy ignition of cool furnace, quick combustion, high heating efficiency, strong fire power, being free from blow-off, less exhaust emission, and the like, and is specially fit for the biomass direct combustion furnace.
Description
Technical field
The present invention relates to a kind of biomass direct-fired furnace, relate to particularly that the auxiliary air of a kind of biomass direct-fired furnace in combustion process provides, distributor.
Background technology
Biomass half-gasification oven or biomass direct-fired furnace need all in combustion process that the outside provides once, auxiliary air; Make flameholding, sufficient combustion, existing stove and accessory exists burning insufficient owing to structure, the installation of auxiliary air distributor are unreasonable; The thermal efficiency is low; The black furnace starting time is long and take off problems such as fire, fume emission is big, the burning dust is many, and the auxiliary air distributor is integrated with body of heater, gives and clears up, safeguards that body of heater all makes troubles.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, handling ease, auxiliary air distribute rationally makes igniting easily, sufficient combustion, and with the auxiliary air distributor of body of heater for the biomass direct-fired furnace that flexibly connects.
The present invention realizes through following technical scheme.
A kind of auxiliary air distributor of biomass direct-fired furnace is placed on the top of stove tube, and it is the cavity body that is surrounded by inwall, outer wall, upper wall and diapire, and there is fire hole at the middle part, has air admission hole, inwall to have venthole one on the outer wall, has venthole two on the diapire.
The present invention can also come further to realize through following technical measures.
The venthole one of said inwall is the strip crevice hole, and the venthole two of said diapire is the strip crevice hole, and the strip crevice pore structure makes the air-flow rotation, and the black furnace igniting is easy, and it is more abundant to burn, and the thermal efficiency is higher; Said outer wall is back taper, prevents because of temperature distortion and body of heater assembling tension or loosening; The fire hole of said auxiliary air distributor top is placed with the fire-collection ring of taper, makes that firepower is powerful, flame is more concentrated, improves the thermal efficiency.
It is simple in structure for the auxiliary air distributor of a kind of biomass direct-fired furnace provided by the invention, handling ease, and its inner chamber is through the strip crevice hole stove tube air feed under fire hole and diapire simultaneously; Make the auxiliary air rotation; It is more abundant to burn, and has easy, the quick combustion of black furnace igniting, and the thermal efficiency is high; Characteristics such as firepower is powerful, do not take off fire, toxic emission is few; And desirablely go out body of heater, make things convenient for operations such as charging in the use, reinforced and cleaning, maintenance, be suitable for the use of biomass half-gasification oven or biomass direct-fired furnace.
Description of drawings
Fig. 1 is the structural representation of the auxiliary air distributor of biomass direct-fired furnace.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explain:
Embodiment one, and the auxiliary air distributor of biomass direct-fired furnace is as shown in Figure 1, is the toroidal cavity body that is surrounded by inwall 1, outer wall 2, upper wall 3 and diapire 4, and there is fire hole 5 at the middle part; Outer wall 2 is back taper, has equally distributed some air admission holes 6 along conical surface circumference; Have the venthole 1 of shutter shape on the inwall 1, have the venthole 28 of shutter shape on the diapire 4; 4 respectively have twice reinforcement 9 on upper wall 3 and the diapire.
When installing and using; The auxiliary air distributor of biomass direct-fired furnace and body of heater flexibly connect; Be placed on the top of stove tube, its outer wall 2 is near the step inwall of body of heater, and air admission hole 6 is connected outside auxiliary air air feed; The outer wall 2 of back taper can prevent because of temperature distortion and body of heater assembling tension or loosening, and convenient the taking-up; Because biomass direct-fired furnace is fuel burning from top to bottom in the stove tube; Flame is upwards scurried out from fire hole, so when igniting, the venthole 28 of the shutter shape of diapire 4 is eddy flow shape air feed downwards; Promptly to stove tube upper end air feed; Ventilate, sufficient combustion, easy quick combustion of fuel ignition and flue dust are few; During normal combustion, the combustion-supporting material of primary air is at the stove cylinder roasting, and the venthole 28 of the venthole 1 of the shutter shape of inwall 1 and the shutter shape of diapire 4 is respectively to fire hole and stove tube top eddy flow air feed; Make burning more abundant, firepower is more powerful, and the thermal efficiency improves greatly; Toxic emission is few, and flame is upwards scurried out from the fire hole rotation, and fire hole 5 tops are placed with the fire-collection ring 10 of taper; Make flame more concentrated, improve the thermal efficiency.
