Abstract

The utility model relates to burning equipment for a boiler, in particular to a high-power double-cyclone burning semi-premix gas burner. The gas burner comprises a gas inlet, an air inlet and a burning stabilizer, wherein the gas inlet is connected with a gas passage; the outlet end of the gas passage is uniformly provided with gas cyclone plates in the circumferential direction; the air inlet is connected with an air passage; the air passage is formed on the outer ring of the gas passage; the outlet end of the air passage is uniformly provided with air cyclone plates in the circumferential direction; the direction of the air cyclone plates is opposite to that of the gas cyclone plates; the inner ring of the gas passage is provided with a high-energy automatic burning torch and a flame detector; and the burning stabilizer is connected at the front ends of the gas passage and the air passage. Because opposite double cyclone is adopted, the mixing is instantaneously completed, the flame is short, the length of the flame is 60 percent of that of the conventional burner, the power is high, the number of burners arranged in a single boiler is reduced, the burning control system is greatly simplified, the generation amount of NOx can be reduced by about 40 percent, and the burning stabilizer can stabilize ignition and ensure no fire extinguishment.

Description

High-power bispin stream burning half premixed gas burner
Technical field
The utility model relates to a kind of boiler combustion apparatus, specifically a kind of high-power bispin stream burning half premixed gas burner.
Background technology
Along with China's rapid development of economy, the continuous increase of iron and steel and coke output, its subsidiary product coal gas also increases thereupon, is energy-saving and emission-reduction, and resource makes full use of, and coal gas is many to be utilized as boiler oil.Make gas burner also obtain widespread.But at present the most complex structure of state's inner burner, flame is long, power is low, the separate unit boiler arranges that burner quantity is many, control system is complicated.
Summary of the invention
The purpose of this utility model provide a kind of bispin stream, simple in structure, flame short, high-power, mix, combustion stablized high-power bispin stream burning premixed gas burner partly.
The utility model comprises gas inlet, air intlet, the flow of coal gas sidespin, the air side spinning disk, automatic burning torch, flame detector, stabilizer, gas inlet connects gas passage, the gas passage port of export evenly is provided with the flow of coal gas sidespin by circumferencial direction, air intlet connects air duct, air duct is located at the gas passage outer ring, the air duct port of export evenly is provided with the air side spinning disk by circumferencial direction, the air side spinning disk is opposite with coal gas sidespin flow direction, the gas passage inner ring is provided with the automatic burning torch of high energy, and gas passage is connected stabilizer with the air duct front end.
The gas passage inner ring is provided with flame detector.
Air enters air duct from air intlet, rotate by the air side spinning disk, coal gas enters gas passage from gas inlet, rotate by the flow of coal gas sidespin, the rotation direction of coal gas and air is opposite, moment finishes mixing in outlet, and the gas that mixes is lighted by automatic burning torch and entered burner hearth, the flame burning situation can detect by flame detector, to realize automatic control.
Automatically burning torch elder generation firing point internal heat rifle, the igniting air gun coal gas that ignites again adopts two sections igniting.
Above-mentioned burner adopts the bispin flow structure, coal gas is opposite with the air rotation direction, mix burning again moment in outlet, the length of flame shortens greatly, burner outlet is provided with the stabilizer of making of refractory material about 300mm, guarantee that the stable radiation that the flame root has high temperature to water material feeding catches fire, guarantee that burner does not take off fire.Can the smooth combustion low-pressure fuel gas, combustion gas does not need the secondary pressurization, and operating cost is low.
Above-mentioned burner coal gas infeeds from the center, and the outer ring air produces rotation through spinning disk, strengthens through narrow quirk rotation, so form a negative pressuren zone in air-flow, impels flue gas reflux cycle voluntarily.Under the acting in conjunction of rotational flow air and smoke backflow, quickened coal gas and Air mixing, increased the uniformity of mixing simultaneously, therefore can realize low oxygen combustion, flame temperature is more even, prevents the generation of localized hyperthermia.Because flue gas self circulation, flame holding is good, has also played the effect that reduces combustion zone oxygen concentration and temperature simultaneously.In addition, narrow cylinder quirk can prevent combustion gas in the quirk internal combustion, and a large amount of gas-flows burn in the quirk exit after going out quirk, and radiating condition is good, and ignition temperature decreases, and can reduce the growing amount of NOx.
The utility model has following advantage compared with prior art:
The utility model is owing to adopted bispin stream, coal gas is opposite with the air rotation direction, mixes moment and finishes, and flame is short, the length of flame is 60% of a normal burner, power is big, and the separate unit boiler arranges that burner quantity is few, and gas piping is simple, cutting valve quantity soon reduces, gas control system is simplified greatly, and investment reduces, and security improves.Can reduce by the growing amount of 40% left and right sides NOx, stabilizer energy stable ignition guarantees not take off fire.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. gas inlet, 2. automatic burning torch, 3. flame detector, 4. air intlet, 5. air side spinning disk, the 6. flow of coal gas sidespin, 7. stabilizer.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
The utility model comprises gas inlet 1, air intlet 4, coal gas sidespin flow 6, air side spinning disk 5, automatic burning torch 2, flame detector 3, stabilizer 7, gas inlet 1 connects gas passage, the gas passage port of export evenly is provided with coal gas sidespin flow 6 by circumferencial direction, air intlet 4 connects air duct, air duct is located at the gas passage outer ring, the air duct port of export evenly is provided with air side spinning disk 5 by circumferencial direction, air side spinning disk 5 is opposite with coal gas sidespin flow 6 directions, the gas passage inner ring is provided with the automatic burning torch 2 of high energy, and gas passage is connected stabilizer 7 with the air duct front end.
The gas passage inner ring also is provided with flame detector 3.
Air enters air duct from air intlet 4, by 5 rotations of air side spinning disk, coal gas enters gas passage from gas inlet 1, by coal gas sidespin flow 6 rotations, the rotation direction of coal gas and air is opposite, moment finishes mixing in outlet, and the gas that mixes is lighted by automatic burning torch 2 and entered burner hearth, the flame burning situation can detect by flame detector 3, to realize automatic control
