Abstract

The utility model relates to thermal energy technology, in particular to a low pressure gas flat flame No x pre-mix highly-efficient, energy-saving and environment-protection gas burner; wherein, a Venturi tube, a burner nozzle and a pilot burner are all arranged on a stabilizer which is positioned on the lower part of a cylinder; the upper part of the cylinder is peripherally provided with a firepan brick combustion port; the lower part of the cylinder is provided with a butterfly valve which controls the wind volume of the wind inlet. The utility model mixes the gas with a high speed by ejecting the gas into the Venturi tube, carries the gas out of the Venturi tube by means of the wind force to mix with the first inlet air; the mixture is ejected out of the nozzle after being compressed and expanded in the Venturi tube; the second inlet air is ejected out of the firpan mouth to support combustion and directly mix with the pre-mix gas for combustion again. The utility model maintains a sufficient combustion of gas, effectively curbs the existence of NOx in combustion and greatly reduces the NOx content in smoke. At the same time, the combustion is stable and reliable and the flame is strong. The flat flame is conducive to heating of the furnace pipe, which is characterized by an even heat exposure.

Description

The flat flame of low-pressure fuel gas hangs down NOx premixed high-efficiency energy-saving environmental protection gas burner
Technical field
The utility model relates to the heat energy technology, refers in particular to the low NOx premixed high-efficiency energy-saving environmental protection gas burner of the flat flame of a kind of low-pressure fuel gas.
Background technology
The a large amount of burner firing equipments that use of industries such as present domestic petroleum chemical industry, the self-produced low-pressure fuel gas of the sector is a lot, too high by the pressurization cost, enterprise has all adopted low-pressure combustion for the major part of increasing the benefit, burning velocity is slow, flame is unstable, burning is insufficient, and the heating to boiler tube has brought a lot of unfavorable factors like this; Pollute in its exhaust emissions particularly that NOx content exceeds standard in a large number, because what adopt is that general technical measures commonly used reduce NOx and measure not ideal enoughly, and there are defectives such as flame temperature is irregular in a small amount of low-NOx combustor that adopts.
Summary of the invention
The purpose of this utility model is improved at shortcoming in the background technology and problem, and a kind of employing venturi combustion tube group is provided, and the flat flame of the low-pressure fuel gas of twice air intake hangs down NOx premixed high-efficiency energy-saving environmental protection gas burner.
The technical solution of the utility model is: the utility model comprises Venturi tube group, burner, stabilizer, cylindrical shell, brazier brick port, butterfly valve, altar lamp etc., wherein Venturi tube group, burner and altar lamp all are located on the stabilizer, stabilizer is located at the bottom of cylindrical shell, establish the brazier brick port around the top of cylindrical shell, bottom one side of cylindrical shell is provided with the butterfly valve of control air inlet air quantity.
The utility model sprays into Venturi tube by combustion gas, carry out high-speed mixing, utilizing the strength of wind to take combustion gas out of Venturi tube mixes with an air intake air, air mixture is by Venturi tube compression, expansion, spray from nozzle then, the air of secondary air from fire pot mouth ejection, help right, directly and the combustion gas mixed combustion again of premix.The utility model guarantees that fuel combustion is abundant, and the existence that suppresses NOx in the combustion process effectively can reduce the content of NOx in the flue gas significantly, simultaneously flameholding is reliable, and flame is upright and outspoken strong, flat flame to the effect of boiler tube heat absorption significantly, be heated evenly.
