Abstract
The present invention relates to an auxiliary ejection-ejection type flat flame burner which is a novel burner composed of an ejector and a cyclone. Wind is not blown by a blower, and air required during combustion is introduced by gas injection action. When an injected air amount can not meet combustion requirements, a small amount of compressed air is introduced from a central tube of the burner to aid gas in injecting the air so as to enhance combustion efficiency. The cyclone has the function that airflow rotates to form a flat surface flame. A flame holder is arranged in the cyclone for preventing backfire, so that the stable working range of the burner is widened. The burner has the advantages of high combustion efficiency, rapid temperature rise, low noise, gas saving and no consumption of blowing electric energy, can be used for heating furnaces of enterprises of metallurgy, machinery, chemical industry, etc. and has great benefit for national economy.
Description
What the present invention relates to is a kind of injecting type flat flame burner that is used for heating furnace.
At present, heating furnace both domestic and external generally uses injecting type burner and Flat Flame Gas Nozzle, goes out the sort of injecting type flat flame burner as description in the 283rd page of " Combustion-combustion technology outline " volume two (April nineteen eighty-three is compiled by Engineering Thermophysics teaching and research group of Nanjing Polytechnical College) in nearly two, three years again.Injecting type burner stove programming rate is slow though this kind burner has overcome, non-uniform temperature, big and the Flat Flame Gas Nozzle of gas consumption amount needs the blower fan air blast, the shortcoming of consumed power, but using high heating value gas or gas pressure when low, because air inducing quantity not sufficient, and the phenomenon of generation incomplete combustion.
At the problem that above-mentioned injecting type flat flame burner exists, invent a kind of spray-injecting type flat flame burner that helps.
Main points of the present invention: helping spray-injecting type flat flame burner is to be provided with one to help spray formula injector to be connected with it in the cyclone porch.This injector is by nozzle (1), inlet scoop (2), mixing tube (3), diffuser pipe (a 4) and central tube (5) is set in nozzle (1) inside forms.Describe content of the present invention in detail below in conjunction with accompanying drawing.
Accompanying drawing 1 helps spray-injecting type flat flame burner schematic diagram.
Accompanying drawing 2 helps spray-injecting type flat flame burner generalized section.
Help spray-injecting type flat flame burner by helping spray formula injector and cyclone (6) to be formed.The higher coal gas of pressure sprays from nozzle (1) high speed, by suction inlet (2) injection air from environment, mixes with coal gas in mixing tube (3), enters cyclone (6) after diffuser pipe (4) boosts.Burning mixture forms swirling eddy and enters burner block (8) burning in cyclone (6), and forms flat flame.When the gas pressure that uses is low, less or when using high heating value gas, the air capacity that needs is more from the air of suction inlet (2) injection.Because the air quantity of injection does not satisfy the needs of burning, the imperfect combustion phenomenon can occur.At this moment allow a spot of compressed air from inner set central tube (5) the high speed ejection of the nozzle (1) that helps spray formula injector, form additional draft, help coal gas injection air, make burning fully.According to the needs of burning, regulate air supply, just can reach the purpose of control furnace atmosphere.
Very easily tempering of the premixed combustion of coal gas and air.A flameholder (7) is set in cyclone (6) for this reason.Move up and down the position of flameholder (7), just can change the sectional area of mixed gas outlet, thereby the flow velocity of mist is changed.When the rate of outflow of mist during greater than flame propagation velocity, just can prevent tempering, make flameholding.
Spray-injecting type the flat flame burner that helps of the present invention is a kind of efficiency energy saving burner.It has quick heating, and burning is complete, the characteristics of uniformity of temperature profile in the flame stabilization, stove.Compare with the injecting type burner, the black furnace heating-up time shortens 2/3, saves coal gas 30%.Compare with the blast gas flat flame burner, it replaces blower fan with injector, saves energy, and noise is low.Compare with the injecting type flat flame burner, it is applicable to the coal gas of various different calorific values.
Help spray-injecting type flat flame burner to be applicable to metallurgy, machinery, the heating furnace of enterprises such as chemical industry.
Claims (1)
1, a kind of injecting type flat flame burner, it is made of injector and cyclone, wherein injector is the nozzle (1) that can spray elevated pressures coal gas by, can from environment, introduce the suction inlet (2) of air, mixing tube (3) and diffuser pipe (4) are formed, the inside that it is characterized in that said nozzle (1) is provided with a central tube (5), and central tube (5) can spray the small amount of compression air at a high speed, helps coal gas injection air.
