Background technology
The industrial furnace combustion gas is burnt and is chewed warm and hot forging, the Technology for Heating Processing that is used in the machining more, and the manufacturing firing equipment of silicate etc., it is one of them critical component that burning is chewed.Existing burning is chewed substantially and is made up of shell, Gas Pipe, air intake duct, eddy flow tray, nozzle, combustor outer casing, igniting and flame monitor etc.Nozzle places the port of export of Gas Pipe, and the seal head end of existing nozzle is provided with some axial through holes, and this hole mainly is to be used for axially spraying into of combustion gas.Because this hole concentrates near the axle center, therefore, the completeness and the utilization rate of fuel gas buring are lower.Remove in addition, burning is chewed another vitals---eddy flow tray in addition, it is to send into air to the combustion chamber that eddy flow tray mainly acts on, existing eddy flow tray only is shaped on the axial gas port of a circle and axis parallel, that is to say that fresh air enters combustion chamber and combustion gas mixing from axial gas port, because the axial setting of through hole, limited air send into direction and with fully the mixing of combustion gas, so axially the structure of gas port is unfavorable for the completing combustion of combustion gas and is an impediment to the raising of the thermal efficiency.
The utility model content
The purpose of this utility model is for overcoming existing existing incomplete combustion of industrial furnace fuel burner nozzle and the low defective of the thermal efficiency, to chew and propose a kind of improved combustion gas burning.The utility model is to adopt following technical scheme to realize: the improved combustion gas of a kind of industrial furnace is burnt and is chewed, comprise housing, Gas Pipe, nozzle, eddy flow tray, air intake duct, combustor outer casing, igniting and flame monitor, the seal head end that it is characterized in that nozzle is provided with the radial air inlet hole and bores to air admission hole, and eddy flow tray is provided with air slot and bores to gas port; The end face edge of nozzle seal head end is set to taper seat, and to air admission hole, the tube wall of seal head end is provided with some radial air inlets hole along the some awls perpendicular to the conical surface of being circumferentially with of taper seat, and the cone-apex angle of seal head end taper seat is made as 50 °～160 °; Air slot is located at the periphery of eddy flow tray uniformly, air slot is provided with the angle of deflection with respect to the axis direction of eddy flow tray, air slot is made as between 10 °～60 ° with respect to the deflection angle of eddy flow tray axis direction, the number of air slot is no less than 6, and the section configuration of air slot is rectangle or circular arc; Eddy flow tray awl all intersect to the center line of gas port eddy flow tray axial line a bit, this intersection point can be located at the left side or the right side of eddy flow tray, awl is arranged between 10 °～40 ° to the angle that gas port center line and eddy flow tray axial line are intersected; Air slot with respect to the direction of the axial line deflection of eddy flow tray can be made as left avertence to or right avertence to; The number in nozzle seal head end radial air inlet hole is no less than 8, and nozzle seal head end awl is no less than 8 to the number of air admission hole.
Chew by the improved combustion gas burning of industrial furnace that this programme is implemented, because nozzle is provided with radial hole and bores to the hole, the straying quatity and the projected area of combustion gas have been strengthened from structure, axial air slot of eddy flow tray and awl are to the compound action of the spiral air flow of gas port in addition, strengthen the air inflow of fresh air and improved flow velocity, significantly improved the combustion completion and the thermal efficiency of combustion gas.The utility model is rational in infrastructure, effective, is a kind of useful improvement.

Fig. 2 is the axial broken section structural representation of nozzle among Fig. 1;
Fig. 3 is the axial broken section structural representation of eddy flow tray among Fig. 1, and Fig. 4 is the left view of Fig. 3.
The specific embodiment
Be described in further detail with regard to this embodiment in conjunction with the accompanying drawings.The illustrated burning of present embodiment is chewed by housing 1, Gas Pipe 2, nozzle 5, eddy flow tray 4, air intake duct 3, combustor outer casing 7, igniting and flame monitor 6 are formed, material does not improve combustibility and improves the thermal efficiency, the only axial admission of former nozzle seal head end hole changed be made as radial air inlet hole 520 and awl to air admission hole 530, said awl is that the end face edge of nozzle seal head end 51 is arranged to taper seat 53 to air admission hole, the cone-apex angle of this taper seat is made as 60 °, this cone-apex angle can be chosen between 50 °～160 °, along taper seat 53 be circumferentially with 8 awls perpendicular to the conical surface to air admission hole 530, the tube wall 52 of seal head end 51 is provided with 8 radial air inlet holes 520.For strengthening the air inflow of air, periphery at eddy flow tray 4 is provided with the air slot 41 that 8 end faces are rectangle (can also be circular arc) uniformly, for impelling the air-flow rotation, be provided with the angle α of 20 ° of right sides (also can a left side) deflection at air slot 41 with respect to the axis direction of eddy flow tray 4, this deflection angle α can choose between 10 °～60 °.For improving the original axial input mode of air, axial pore is made the axle center of oblique eddy flow tray, and make each awl all intersect at 1 C of the axial line of eddy flow tray to the center line of gas port 40, when intersection point C is located at the right side of eddy flow tray (by illustrated right side), awl causes air-flow to be beaming type input combustion chamber to gas port, otherwise, when the C point meets at the left side of eddy flow tray, awl causes air-flow to be divergence form input combustion chamber to gas port, the input mode of these two kinds of air-flows all helps the completing combustion of combustion gas in the combustion chamber, and the angle β that awl is intersected to gas port center line and eddy flow tray axial line chooses 20 ° between 10 °～40 °.
