Description
Technical field
The present invention relates to a kind of Fluidized Boiler Bed, specifically a kind of Fluidized Boiler Bed down-firing combustion
Device is burnt, Sector of Cfb Boilers is belonged to.
Background technology
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 stove generally uses air compartment both sides air inlet mode, but is partial to boiler side since First air air preheater exports, and one
Secondary hot air duct often both 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 both sides one time, increases duct resistance, occupies limited operating space.
Invention content
It is an object of the present invention to overcome the above deficiencies, to provide a kind of Fluidized Boiler Bed down-firing combustion
Device is burnt, a hot air duct structure can be effectively simplified, reduces duct resistance, makes air compartment wind pressure wind-warm syndrome evenly, reduces bed
Upper burning air feed dead zone.
According to technical solution provided by the invention, a kind of Fluidized Boiler Bed down-firing burner includes oil firing
Device, igniting mix wind combustion chamber, igniting mixes wind main air duct and boiler air compartment, it is characterized in that：The side of boiler air compartment is sequentially connected a little
The mixed wind main air duct of fire, igniting mix wind combustion chamber and oil burner, and the port of oil burner stretches into igniting and mixes in wind combustion chamber, point
The mixed wind main air duct side of fire is equipped with a hot-air mouth, and one time hot-air mouth is open towards furnace lower central.
Further, it is cylindrical structure, including the combustion chamber high-temperature-resistant layer being arranged inside and outside and burning to light a fire and mix wind combustion chamber
Room insulating layer
Further, combustion chamber high-temperature-resistant layer uses the brick system of mullite, combustion chamber insulating layer to use the brick system of floating bead.
Further, it is circular cone structure to light a fire and mix wind main air duct, 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, it lights a fire and mixes wind main air duct side equipped with inspection manhole, 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 madial wall, light a fire and mix on wind main air duct madial wall by grabbing
Nail pours into a mould air duct insulating layer and air duct flame retardant coating successively from outside to inside.
Compared with the prior art the present invention has the following advantages：
The invention has the advantages of simple structure, compactness and reasonable structure, can effectively simplify a hot air duct structure, reduces duct resistance, makes air compartment
Wind pressure wind-warm syndrome evenly, reduces burning air feed dead zone on bed.
