Description
Technical field
The invention belongs to heat energy apparatus fields, more particularly to a kind of combustion head for combustion of industrial boiler device.
Background technique
Burner is a kind of by fuel and air, is sent into furnace by required concentration, speed, turbulivity and hybrid mode
Thorax, and enable the heat energy apparatus of fuel stable ignition and burning in burner hearth.
In the combustion process of fuel, the generation of nitrogen oxides is some of combustion reaction: the nitrogen oxidation for generation of burning
If owner NO and NO2, it is referred to as NOx, the NOx in atmosphere can be generated as nitric acid rain after being dissolved in water, and acid rain can bring environment
Extensive harm, causes huge economic loss.
For the discharge for reducing NOx, application number 201821366267.2 report it is a kind of be equipped with multiple spout (first nozzle,
Secondary spout and three times spout) combustion head.The combustion head can efficiently reduce the discharge of NOx.But it sends out in actual use
Existing, the aperture of spout is less than the aperture of first nozzle due to secondary spout and three times, the gas flow rate and pressure of first nozzle and
Other spouts are inconsistent, so that the temperature that the formation height of the entire combustion zone of combustion head is different, relative temperature are higher
Region is easy to produce NOx.
Summary of the invention
The object of the present invention is to provide a kind of combustion heads of the burner of low nitrogen, to improve the defects of well-known technique.
To achieve the above object, combustion head provided by the invention, structure are: combustion head inner ring is equipped with the rotation for stablizing flame
Flow table, eddy flow tray outer ring are surrounded with first nozzle, three times spout and secondary spout, and secondary spout and three in order from the inside to the outside
One end of secondary spout is connected as an air inlet；Electric gas butterfly valve is installed in the pipeline of first nozzle, and is once being sprayed
Mouth is respectively equipped at least one pyrostat with secondary nozzle, and the pyrostat connects and controls electric gas butterfly
Valve.
The combustion head, in which: the first nozzle is set there are three spout, offers a main jet below first nozzle
Mouthful, it is respectively provided with a cap jet across the land positioned at the top two sides of main injection jet, the aperture of cap jet is less than the aperture of main injection jet.
The combustion head, in which: the pyrostat connects a microprocessor, controls and adjusts by the microprocessor
Section electric Gas fuel butterfly valve.
The combustion head, in which: the eddy flow tray is set on the axis of combustion head.
The combustion head, in which: the secondary spout is identical with the aperture of spout three times.
The quantity and/or bore of first nozzle are proportional to the tonnage of Industrial Boiler, the quantity and mouth of tonnage difference spout
Diameter is all different, corresponding secondary spout and the three times quantity of spout and bore with first nozzle the variation of quantity and bore.
The effect of combustion head of the present invention is:
1) one big flame is divided into several flammules, since flammule heat dissipation area is big, flame temperature is lower, makes nitrogen oxygen
Compound is declined；Further, since flammule shortens residence time of the gases such as oxygen, nitrogen in flame, have to nitrogen oxides
Apparent inhibiting effect.
2) due to being assembled with pyrostat in first nozzle and secondary nozzle, pass through the signal control of pyrostat
System and adjusting electric gas butterfly valve, thus the ignition temperature of control and adjusting first nozzle.
Detailed description of the invention
