Description

Biomass flue gas recycles low-NO_x burner
Technical field
The present invention relates to burning boiler technical field, is specially biomass flue gas recycling low-NO_x burner.
Background technology
At present, the method for discharged nitrous oxides is controlled to be divided into two major classes:1. low NOx combusting technology -- control in combustion The generation of nitrogen oxides processed;2. gas denitrifying technology -- reduce the nitrogen oxides after generation.
The NOX of combustion process generation mainly has 3 kinds of heating power type, fuel type and Quick-type, and wherein fuel type NO accounts for total generation The 60%-80% of amount, reaches as high as 90%, thermal NO x when temperature is sufficiently high up to 20%, the ratio that Quick-type NOx is accounted for Minimum, can be neglected.
Existing burning boiler flue gas recirculation cannot burn well, while it is of high cost to burn, and utilization rate is low, does not save Can, it is not environmentally friendly enough.
The content of the invention
It is an object of the invention to provide biomass flue gas to recycle low-NO_x burner, to solve in above-mentioned background technology The problem of proposition, possessed beneficial effect are:By being provided with recirculation blower and deduster on the right side of furnace body, to flue gas Cycling and reutilization is carried out, while purifying smoke, more environmentally friendly utilization rate higher are more efficient energy saving;Secondly, by being set in air inlet pipe Air preheater is equipped with, the air being pumped into by suction ventilator is heated, reduction cold air enters the cooling degree in furnace body, More time saving resource-saving, it is more efficient quick.
To achieve the above object, the present invention provides following technical solution:Biomass flue gas recycles low-NO_x burner, bag Furnace body is included, the upper table wall of the furnace body has been bolted feeding pipe, and the left-handed watch wall of furnace body is fixed with successively from top to bottom Smoke outlet and slag-draining device, the preceding table wall of the furnace body are provided with observation perspective board, and the right table wall of furnace body is from top to bottom successively Recirculation blower and air inlet pipe are provided with, the inside of the furnace body is provided with fire grate, between the recirculation blower and air inlet pipe Deduster is installed on fixed circulation air hose, air preheater is installed, and the inside of air inlet pipe is set in the air inlet pipe There is energy-saving appliance, the right table wall of the air inlet pipe is fixed with suction ventilator.
Preferably, the observation perspective board is high temperature resistant organic glass material members.
Preferably, the air inlet pipe and circulation air hose are stainless steel component.
Preferably, the model GY4-73-20D of the recirculation blower and suction ventilator.
Compared with prior art, the beneficial effects of the invention are as follows:The equipment on the right side of furnace body by being provided with recycling Wind turbine and deduster, cycling and reutilization is carried out to flue gas, while purifying smoke, more environmentally friendly utilization rate higher are more efficient energy saving;Its It is secondary, by being provided with air preheater in air inlet pipe, the air being pumped into by suction ventilator is heated, reduce cold air into Enter the cooling degree in furnace body, more time saving resource-saving is more efficient quick;Finally, observation is provided with by the preceding table wall in furnace body Window, the convenient observation to burning in stove are apparent to understand.
