The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to specify technical scheme of the present invention.
The air blast diffusion flame burner is owing to the restriction in space, and combustion gas and Air mixing distance are very short, can not fully mix, and cause incomplete combustion, and combustion noise is bigger simultaneously
There is the restriction in space in the air blast diffusion flame burner, and the distance that combustion gas mixes with air is very short, can not fully mix, and causes incomplete combustion, and combustion noise is big simultaneously.
All-premixing burner has overcome the shortcoming that above-mentioned burning is insufficient, combustion noise is big, but has following shortcoming: the flame adjustable range is less, and stable source of the gas need be provided; When using the higher combustion gas of some combustion potential, be prone to produce the tempering tendency; If the space of burner is restricted, combustion gas and Air mixing zone design also are difficult to reach both well-mixed purposes.
In order to overcome above-mentioned shortcoming, the partly-premixed burner of the present invention comprises following structure, hereinafter will be described in detail this with reference to accompanying drawing.
The partly-premixed burner of the present invention; Comprise nozzle 1 and air inlet pipe 6, nozzle 1 is connected with air inlet pipe 6, baffle liner 2 and outer baffle liner 3 in also comprising; Interior baffle liner 2 is provided with around nozzle 1; Outer baffle liner 3 is provided with around interior baffle liner 2, forms first mixed zone 7 between interior baffle liner 2 and the nozzle 1, forms second mixed zone 8 between outer baffle liner 3 and the interior baffle liner 2.Fuel gas enters into nozzle 1 through air inlet pipe 6, and the venthole 10 by nozzle 1 gets in the interior baffle liner 2 again.Fuel gas in getting in the baffle liner 2 mixes with the part air of baffle liner 2 in axial the entering, and the zone that the fuel gas in the interior baffle liner 2 mixes with the part air is first mixed zone 7.Another part air gets in the outer baffle liner 3, another part air in the fuel gas in first mixed zone 7 and part Air mixing gas and the outer baffle liner 3 through interior baffle liner 2 with outside the clearance type breach 11 of baffle liner 3 lead baffle liner 3 interior mixing outside.The zone that the mist that fuel gas in the outer baffle liner 3 in above-mentioned first mixed zone 7 mixes with the part air mixes with another part air is second mixed zone 8, the i.e. combustion zone.
The present invention also comprises shell, and shell is arranged at the outside of outer baffle liner 3, forms an air chamber 9 with outer baffle liner 3.A plurality of ventholes 10 are set on the side of nozzle 1.Venthole 10 is provided with 6, is evenly distributed on the sidewall of nozzle 1 upper end.The bottom surface of outer baffle liner 3 is provided with down shrouding 14, and a plurality of circular holes 12 evenly are set on the following shrouding 14.The upper bottom surface of interior baffle liner 2 is provided with upper sealing plate 13, and upper sealing plate 13 is connected by bolt 4 with nozzle 1.The shape of upper sealing plate 13 and following shrouding 14 is annular.
A plurality of and interior baffle liner 2 is set on the sidewall of interior baffle liner 2 axially reaches tangential clearance type breach 11 in a certain angle.A plurality of and outer baffle liner 3 is set on the sidewall of outer baffle liner 3 axially reaches tangential clearance type breach 11 in a certain angle.Axially reach the tangential angle and be 20 °-30 °.Clearance type breach 11 is bar shaped, the tangential direction 11 of clearance type breach 11 interior baffle liner 2 with outside the direction of baffle liner 3 in the same way, clearance type breach 11 is via being stamped to form.Flow passage component on interior baffle liner 2, the outer baffle liner 3; Form by rammed strip crevice formula breach 11; The shape of breach makes air-flow get into second mixed zone 8 along tangential direction, and the flow direction of mist and air is in the same way, and the length direction of these breach with certain included angle is axially arranged; Like this, the main flow of two bursts of gas formation is to form mobile that rotation makes progress in the combustion zone in second mixed zone 8.
The invention has the advantages that application principle is simple,, can find out according to the direction of fluid on the burner sketch; The direction of each burst gas flow is reasonable; Flow resistance is little, main flow of gas in the combustion zone holdup time long, therefore; Help fully mixing of combustion gas and air, reduce the consumption of supplementary energy and reduce combustion noise.
Get into the amount of the air in the first premix district, control by the hole that outer baffle liner 3 lower annular distribute.And whole mixing of combustion gas and air is that realize second mixed zone, therefore, eliminated the possibility of tempering.
Structurally, the handling ease of product component realizes through punching press, welding and general machining.
Axially be uniformly distributed with 6 apertures on the nozzle 1, in order to control fuel gas flow, nozzle 1 connects with fuel gas air inlet pipe 6 with the mode that is threaded, and simultaneously outer baffle liner 3 is fixed on the housing 5.According to the difference of fuel gas kind and burner thermic load, the work of changing nozzle 1 will be very simple.
Above-mentioned design example only is used for that the present invention will be described, does not constitute the restriction to the claim scope, and other substantial equivalence means that it may occur to persons skilled in the art that are all in claim scope of the present invention.
