Description
Technical field
The present invention relates to a kind of fuel burner nozzle, be meant the quasi high-speed fuel burner nozzle of a kind of industrial kiln especially.
Background technology
Burner is being commonly called as of the burner used on the industrial fuel stove, can be regarded as the abbreviation of " nozzle that makes a fire ".Be commonly referred to as the burner body part, fuel inlet, air intake and squit hole are arranged, play the effect that distributes fuel and combustion air and spray after-combustion in a certain way.
The fuel burner nozzle of industrial kiln in the prior art, as be used for the natural gas burner of ceramic roller kiln, with reference to Fig. 1; Comprise the blender 100 of burner end '; The gas outlet 10 of the some 45 ° of inclinations of blender 100 ' be provided with ', the gas outlet 20 of some levels ', the straight combustion air outlet 30 of plurality of vertical ' and some rotation combustion airs outlet 40 ', the direction of travel among the figure after the straight combustion air of a ' expression and the combustion gas collision, the direction of travel after colliding with the barrel that burns is again collided in straight combustion air of b ' expression and combustion gas; Compound direction after c ' expression combustion air and the combustion gas mixing; D ' expression flame contours, the length of flame 1 that this burner forms ' less than 100mm, flame is short; Flame speed is low, causes the internal-external temperature difference on the kiln cross section bigger easily.
And if use burner shown in Figure 1, avoid causing on the kiln cross section internal-external temperature difference more very the difficulty.And to avoid the big use high combustion rate burner that just needs of internal-external temperature difference on the kiln cross section; High combustion rate burner then must install devices such as ignition, fire cover additional; Complex structure, big, the expensive of volume, price is up to 10-30 times of common burner, and the number of the required burner of ceramic roller kiln is more; A general tunnel cave needs burner 30-250 not wait, so high combustion rate burner is difficult to be used on the tunnel cave.
Summary of the invention
Main purpose of the present invention is to overcome the shortcoming of prior art, provides a kind of industrial kiln quasi high-speed fuel burner nozzle, when avoiding causing internal-external temperature difference on the kiln cross section bigger and cost lower, satisfy the demand of Industrial Stoves to fuel burner nozzle.
The present invention adopts following technical scheme:
The quasi high-speed fuel burner nozzle of a kind of industrial kiln comprises a housing, is provided with blast tube and combustion air passage in this housing, and is provided with a blender at the end of this blast tube and combustion air passage; This blender is made up of at second mixer element of this combustion air channel end in this blast tube terminal first mixer element and shutoff shutoff, and this first mixer element is provided with some gas outlets, and this second mixer element is provided with some combustion air outlets; This gas outlet is obliquely installed, with the angle of vertical direction be 20-40 °; The outlet of this combustion air is obliquely installed, with the angle of vertical direction be 20-40 °; And flow to this gas outlet direction along combustion gas or combustion air and intersect with this combustion air Way out, the phase intersection mixes combustion gas and air, the burning velocity height.
Preferably, the angle of said gas outlet and vertical direction is 25-35 °, and said combustion air outlet is 25-35 ° with the angle of vertical direction.The control of these two angles is very crucial, and angle is excessive, and the length of flame is short, and speed is low, angle too small, and combustion gas and combustion air mix uneven, and it is inhomogeneous to burn.
Preferably, said combustion air passage is around being enclosed in outside the said blast tube; The center of said first mixer element raises up and forms first inclined plane from this central protuberance outward inclining, and said gas outlet is located on this first inclined plane; Said second mixer element is looped around this first mixer element arranged outside and is formed slopely second inclined plane to the inside, and said combustion air outlet is located on this second inclined plane.
Preferably, the number of said gas outlet is 6-20, evenly is arranged on said first inclined plane along circumference; The number of said combustion air outlet is 6-20, evenly is arranged on said second inclined plane along circumference.
Preferably, the number of said gas outlet and the outlet of said combustion air equates, and is corresponding one by one setting in a circumferential direction.
Preferably, the outlet of said gas outlet and said combustion air is circle.
Preferably, the ratio of said gas outlet area and said combustion air discharge area is 1: 10.This area burnt than excessive or too small all being unfavorable for, natural gas burning is the most abundant in this scope, and excess air is minimum, and ignition temperature is the highest.
Preferably, said blender is an integral structure, and the high combustion rate burner that contrasts corresponding energy has the carborundum of saving sleeve, electronic ignition system, has both improved reliability, reduces cost again, has the same high-speed flame speed of high combustion rate burner simultaneously.
The quasi high-speed fuel burner nozzle of a kind of industrial kiln of the present invention compared with prior art, have following beneficial effect: gas outlet is obliquely installed, with the angle of vertical direction be 20-40 °; Combustion air outlet is obliquely installed, with the angle of vertical direction be 20-40 °; And flow to the gas outlet direction and the combustion air Way out intersects along combustion gas or combustion air; Make that the synthetic back of combustion air and combustion gas collision speed is higher, flame does not rotate, rigidity high, the length of flame is bigger, and speed is big, avoids causing the internal-external temperature difference on the kiln cross section bigger, and cost is lower simultaneously, fully satisfies the demand of Industrial Stoves to fuel burner nozzle.
