NOx
Combustion technology cost of investment is high, higher low of the low denitration efficiency of a kind of cost of investment of biomass low-nitrogen burning boiler
NOx
Combustion technology.Biomass fuel is with low
NOx
The combination of combustion technology is a kind of to invest the some effective that low denitration efficiency is higher.
Fuel is in combustion
NOx
Have three kinds of forms: fuel type, heating power type, Quick-type.Wherein fuel type proportion is maximum
60%--80%
；Heating power type at high temperature produces, and Quick-type accounts for
5%
。
Summary of the invention:
The purpose of this utility model is to provide a kind of energy-conservation environmental protection again, burning thorough, the vortex burner biomass low-nitrogen burning boiler that efficiency is high.
Above-mentioned purpose is realized by following technical scheme:
A kind of biomass low-nitrogen burning boiler, its composition includes
:
Vortex burner, described vortex burner connects water cooling chamber one, and described water cooling chamber one connects fires reative cell again, and the described reative cell that fires again connects water cooling chamber two, and described water cooling chamber two connects heat-transfer pipe, and described heat-transfer pipe connects energy-saving appliance.
Described biomass low-nitrogen burning boiler, described fires reative cell connecting secondary wind airduct and tertiary air airduct again, heat exchanger is built with one group of heat convection pipe and one group of energy-conservation tube bank, described water cooling chamber one connects scummer one, the described reative cell that fires again connects scummer two, and described water cooling chamber two connects scummer three.
Described biomass low-nitrogen burning boiler, described vortex burner includes that vertical cyclone burner or horizontal cyclone burner or vertical cyclone burner and horizontal cyclone burner combine, described vertical cyclone burner and described horizontal cyclone burner are all connected with liquefied gas igniter, and described horizontal cyclone burner connects First air airduct.
Beneficial effect:
1.
The most energy-conservation not only environmental protection of this utility model, it is the most economical but also practical environment-friendly boiler product.
Cost of the present utility model increases few, and decreases the huge denitration desulphurization plant of boiler and huge fund input, it becomes possible to reach the effect of desulfurization removing nitric.
The burning of boiler oil of the present utility model is the most abundant；Efficiency of combustion can reach
97%
Above；For biomass fuel popularization and application, provide wide prospect for biomass application on boiler.
Vortex burner of the present utility model is the combined burning mode of main burner and burner again；Vortex burner is the two kinds of modes that combine horizontal vertical or vertical, horizontal.
