Description
Technical field
The utility model relates to a kind of Fluidized Boiler Bed, point under specifically a kind of Fluidized Boiler Bed
Flame burner belongs to Sector of Cfb Boilers.
Background technique
With the development of Technology of Circulating Fluidized Bed Boiler, circulating fluidized bed boiler is efficient with it, environmentally friendly, coal adaptability is wide
Etc. advantages, application it is more and more extensive.Circulating fluidized bed boiler generally uses light oil under bed to light a fire, ignition under bed recirculating fluidized bed pot
The First air of furnace generally uses air compartment two sides air inlet mode, but since First air air preheater outlet is partial to boiler side, and one
Secondary hot air duct often two sides Length discrepancy, causes air compartment wind pressure wind-warm syndrome uneven, or multiple elbows need to be arranged to evenly distribute
The hot air duct of two sides one time, increases duct resistance, occupies limited operating space.
Summary of the invention
In place of the purpose of this utility model is to overcome above-mentioned deficiency, to provide point under a kind of Fluidized Boiler Bed
Flame burner can effectively simplify a hot air duct structure, reduce duct resistance, make air compartment wind pressure wind-warm syndrome more evenly, subtract
Burning air feed dead zone on few bed.
According to technical solution provided by the utility model, a kind of Fluidized Boiler Bed down-firing burner includes oil
Burner, mixed wind combustion chamber of lighting a fire, light a fire mixed wind main air duct and boiler air compartment, it is characterized in that: the side of boiler air compartment successively connects
Contact fire mixes wind main air duct, lights a fire and mix wind combustion chamber and oil burner, and the port of oil burner protrudes into the mixed wind combustion chamber of igniting
In, mixed wind main air duct side of lighting a fire is equipped with a hot-air mouth, and one time hot-air mouth is open towards furnace lower central.
Further, lighting a fire and mixing wind combustion chamber is cylindrical structure, including the combustion chamber high-temperature-resistant layer being arranged inside and outside and burning
Room insulating layer
Further, combustion chamber high-temperature-resistant layer uses the brick system of mullite, and combustion chamber insulating layer uses the brick system of floating bead.
Further, mixed wind main air duct of lighting a fire is circular cone structure, and mixed wind main air duct of lighting a fire is lighted a fire from connection mixes wind burning
Room one end becomes larger to connection boiler air compartment one end cross sectional dimensions.
Further, mixed wind main air duct side is lighted a fire equipped with inspection manhole, and side inspection manhole is opposite with a hot-air mouth
Setting.
Further, it lights a fire to mix and welds bitch on wind main air duct inner sidewall, by grabbing on mixed wind main air duct inner sidewall of lighting a fire
Nail is successively poured air duct insulating layer and air duct flame retardant coating from outside to inside.
Compared with the prior art the utility model has the advantage that
The utility model structure is simple, compact, reasonable, can effectively simplify a hot air duct structure, reduces air duct resistance
Power makes air compartment wind pressure wind-warm syndrome more evenly, reduces air feed dead zone of burning on bed.
Detailed description of the invention
Fig. 1 is the utility model main view.
Description of symbols: 1- oil burner, 2- light a fire mixed wind combustion chamber, 3- light a fire mixed wind main air duct, 4- boiler air compartment,

Specific embodiment
The utility model will be further described in conjunction with the embodiment in attached drawing below:
As shown in Figure 1, the utility model mainly includes oil burner 1, mixed wind combustion chamber 2 of lighting a fire, mixed wind main air duct 3 of lighting a fire
With boiler air compartment 4.
The side of boiler air compartment 4 is sequentially connected the mixed wind main air duct 3 of igniting, light a fire mixed wind combustion chamber 2 and oil burner 1, oil
The port of burner 1 protrudes into the mixed wind combustion chamber 2 of igniting.
The mixed wind combustion chamber 2 of lighting a fire is cylindrical structure, is protected including the combustion chamber high-temperature-resistant layer 7 being arranged inside and outside and combustion chamber
Warm layer 6, combustion chamber high-temperature-resistant layer 7 use the brick system of mullite, and combustion chamber insulating layer 6 uses the brick system of floating bead, cylindric point
The mixed wind combustion chamber 2 of fire ensure that high temperature homogenous combustion when oil drop fire.
The mixed wind main air duct 3 of lighting a fire is circular cone structure, and mixed wind main air duct 3 of lighting a fire is lighted a fire from connection mixes wind combustion chamber 2
One end becomes larger to connection 4 one end cross sectional dimensions of boiler air compartment.
Mixed 3 side of wind main air duct light a fire equipped with a hot-air mouth 5, one time hot-air mouth 5 is open towards in furnace lower part
The heart, uniformly mixed hot wind can be full of bed lower part with diffusion type, reduce air feed dead zone.
Mixed 3 side of wind main air duct light a fire equipped with inspection manhole 9, side inspection manhole 9 is oppositely arranged with a hot-air mouth 5,
