Abstract
The utility model discloses a biomass fuel postcombustion boiler establishes and a boiler. Because the bags is narrow and small, the oxygen suppliment is not enough, the impossible complete combustion of material fuel produces a large amount of combustible gas such as carbon monoxide. Set up the draught fan between combustion chamber and furnace body, the entrance point of draught fan link up through combustible gas inlet tube and combustion chamber inner chamber, and the exit end of draught fan link up with furnace through the combustible gas injection pipe. The draught fan in with the combustion chamber the intact combustible gas such as carbon monoxide of unburned spout intos furnace, carry out postcombustion, messenger biomass fuel complete combustion. The energy saving reduces the boiler operation cost. Avoid flammable gas to discharge the environment that depollutes in the air simultaneously.
Description
Technical field
This utility model sets and a kind of boiler, specifically set and one utilize biomass as fuel, by second-time burning
Boiler.
Background technology
The operation sequence of biomass fuel boiler is, first biomass fuel is rendered to combustor and burns, and ember leads to
Cross chain furnace grate and residue outlet enters burner hearth and burns away.Owing to the bags is narrow and small, supply hypoxgia, fuel can not be complete
Full burning, produces the imflammable gas such as substantial amounts of carbon monoxide.The biomass fuel boiler used on the market at present is to burn
These imflammable gas that room produces are directly discharged in air, not only waste the energy, improve the operating cost of boiler, with
Time also environment can be caused serious pollution.
Summary of the invention
In order to solve above-mentioned technical problem, this utility model provides a kind of secondary combustion of biomass fuel boiler.In burning
Arranging air-introduced machine between room and body of heater, it is through with combustor inner chamber that the entrance point of air-introduced machine introduces pipe by fuel gas, air inducing
The port of export of machine is through with burner hearth by fuel gas playpipe.Air-introduced machine can by carbon monoxide of burning-out unburned in combustor etc.
Combustion property gas sends into burner hearth, carries out second-time burning.Make biomass fuel combustion completely, fully.
This utility model is achieved by the following technical solution: a kind of secondary combustion of biomass fuel boiler, including: stove
Body and chain furnace grate.The inner chamber bottom of body of heater is burner hearth, and vapor lamp is installed on the top of body of heater inner chamber.One end of body of heater arranges combustion
Burning room, described combustor upper end is fuel inlet, set-point, combustor bottom burner.The other end of body of heater arrange smokejack,
Cleaning door and water inlet pipe.It is characterized in that: arrange air-introduced machine between combustor and body of heater, the inlet end of described air-introduced machine passes through
It is through with the upper end of combustor inner chamber that fuel gas introduces pipe, and the outlet side of air-introduced machine is passed through with burner hearth by fuel gas playpipe
Logical.
Described air-introduced machine is arranged on body of heater by fan supporter.
Good effect of the present utility model is:
1, biomass fuel produces the imflammable gas such as substantial amounts of carbon monoxide pass through air-introduced machine when burning Indoor Combustion
Send into burner hearth, carry out second-time burning complete, sufficient.Improve fuel availability, reduce the operating cost of boiler, very the biggest
Minimizing pollution that air is caused.
2, compact conformation, making, simple installation, it is simple to promote the use of.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Accompanying drawing is this utility model structural representation.

Detailed description of the invention:
As shown in drawings, a kind of secondary combustion of biomass fuel boiler, including: body of heater 10 and chain furnace grate 1.Described
The bottom of body of heater 10 inner chamber is burner hearth 3, and vapor lamp 11 is installed on the top of body of heater 10 inner chamber.One end of body of heater 10 arranges combustor 5,
Described combustor 5 upper end is fuel inlet 5-2, set-point, combustor 5 bottom burner 5-1.Biomass fuel 4 is entered by fuel
Mouth 5-2 puts into combustor 5, then by lighting-up tuyere 5-1 ignition.The other end of body of heater 10 arranges smokejack 12, cleaning door
13 and water inlet pipe 14.Biomass fuel waste gas after burner hearth 3 second-time burning is connected to chimney by smokejack 12, then is discharged to big
In gas.Flue dust after burning is cleared up away by cleaning door 13.Vapor lamp 11 is connected with water source by water inlet pipe 14.Its feature
Being: arrange air-introduced machine 8 between combustor 5 and body of heater 10, the inlet end of described air-introduced machine 8 introduces pipe 9 by fuel gas
Through with the upper end of combustor 5 inner chamber；The outlet side of air-introduced machine 8 is through with burner hearth 3 by fuel gas playpipe 7.Due to combustion
Material can not burn in combustor 5 completely, and the imflammable gas such as the carbon monoxide produced, by air-introduced machine 8 by combustor 5
In imflammable gas spurt into burner hearth 3, carry out second-time burning.Make biomass fuel combustion 4 burning-out complete, fully.
The present embodiment air-introduced machine 8 is arranged on body of heater 10 by fan supporter 6.According to the locus of body of heater periphery, also
May be mounted on combustor 5.Or leave body of heater 10 and combustor 5, install on an individual basis.No matter air-introduced machine 8 pacifies
Where it is contained in, all should be included within the scope of this application claims.
