Abstract

The utility model relates to a gas burner of an industrial furnace, in particular to an adjustable-temperature gas burner of an industrial furnace, which is characterized in that a secondary air inlet chamber pipe and a temperature adjusting chamber pipe are respectively arranged on the periphery of a gas burner shell, the secondary air inlet chamber pipe is connected with the temperature adjusting chamber pipe in a communicated manner and placed on the middle periphery of the gas burner shell, the temperature adjusting chamber pipe is placed on the periphery, at a position from a combustion chamber to an outlet end, of the gas burner shell, linking ends of the secondary air inlet chamber pipe and the temperature adjusting chamber pipe are respectively provided with flanges connected via bolts, and the secondary air inlet chamber pipe is provided with an air inlet. By adjusting the flow of cold air for a secondary air inlet pipe orifice, low-temperature air is mixed with high-temperature flue gas, so that the temperature of flue gas sprayed from the gas burner can be adjusted to meet the requirements of different hot processing products on flue gas temperature adjustment. The adjustable-temperature gas burner is simple and reasonable in structure, and has certain significance for expanding the temperature range of hot processing of the industrial furnace.

Description

But temperature adjustment fuel burner nozzle
Technical field
The utility model relates to the fuel burner nozzle of industrial furnace, but particularly about the fuel burner nozzle of a kind of temperature adjustment of industrial furnace.
Background technology
Heat forged, the Technology for Heating Processing that is used for machining at most burnt in the industrial furnace combustion gas, and the manufacturing firing equipment of silicate etc., burner is one of them critical component.Existing burner is made up of shell, Gas Pipe, air intake duct, eddy flow tray, nozzle, combustor outer casing etc.In the hot procedure of workpiece, a large amount of middle low temperature demands for control is arranged, like technologies such as oven dry, steel part tempering, annealing.In direct heating process, existing fuel burner nozzle is easy to cause hot-spot and furnace temperature non-uniform phenomenon because flame temperature is too high, is prone to cause deficiencies such as local burning of processed workpiece and non-uniform temperature.At present, because part hot-working is more and more accurate to the control requirement of shaped article process, as the visual plant in the hot procedure--the effect of-industrial furnace and heat-treatment furnace also highlights day by day.It not only need satisfy the general hot-working requirement of extensive steel grade, and need wherein the heat supply unit---fuel burner nozzle has the heating-up temperature scope of more widening, promptly have control and regulating power from low temperature to high temperature.And the structure of existing fuel burner nozzle; Can't satisfy and realize adjusting requirement to heating-up temperature; Because of the non-adjustable structure of existing fuel burner nozzle to flame temperature; The renders operation personnel are difficult to control and regulate the temperature in the hot procedure on the one hand, and especially some workpiece is to the control of low temperature process process demand; The two existing fuel burner nozzle is higher because of its flame temperature, is prone to produce hot-spot and furnace temperature non-uniform phenomenon, and then causes the local burning and the unequal problem of heating-up temperature of processed workpiece.
The utility model content
The purpose of the utility model is on the basis of existing gas nozzle structure, proposes a kind of temperature adjustment fuel burner nozzle of scalable flue-gas temperature, but uses this temperature adjustment fuel burner nozzle can realize the adjusting control of industrial furnace to flame temperature.For realizing this purpose, adopt following technical scheme, but a kind of temperature adjustment fuel burner nozzle; Comprise fuel burner nozzle, burner shell; The periphery that it is characterized in that the fuel burner nozzle shell is respectively equipped with auxiliary air inlet plenum pipe and tempering room pipe, and auxiliary air inlet plenum pipe connects and connects the tempering room pipe, and auxiliary air inlet plenum pipe places the periphery in fuel burner nozzle shell stage casing; The tempering room pipe places the fuel burner nozzle shell to be positioned at the periphery of combustion chamber to the port of export; The end that connects of auxiliary air inlet plenum pipe and tempering room pipe respectively is provided with flange and is connected by bolt, and auxiliary air inlet plenum pipe is provided with air inlet, and the other end of auxiliary air inlet plenum pipe is set to blind end; The outlet of tempering room pipe is set to the necking end of convergence type.
But press the temperature adjustment fuel burner nozzle that this programme is implemented; Through regulating the cold air flow of auxiliary air air inlet; Cryogenic air is mixed at tempering room with high-temperature flue gas; Thereby realize the purpose of adjustable fuel gas burner ejection flue-gas temperature, to satisfy the demand to the fuel gas temperature adjusting of different hot-working products.The utility model structure is simple and direct, reasonable, has certain meaning to expanding the hot worked temperature requirements scope of industrial furnace.
Description of drawings
Fig. 1 is the axial arrangement sketch map of a kind of embodiment of the utility model.
The specific embodiment
Further specify in conjunction with accompanying drawing.Present embodiment is on the basis of existing fuel burner nozzle 1 and burner shell 11 basic structures; Be provided with the auxiliary air inlet plenum pipe 21 and tempering room pipe 31 that connects connection respectively in the periphery of burner shell 11; Auxiliary air inlet plenum pipe 21 places the periphery in burner shell 11 stage casings; Tempering room pipe 31 places burner shell 11 to be positioned at the periphery of combustion chamber 4 to the port of export, and the end that connects of auxiliary air inlet plenum pipe 21 is provided with annular flange 22, and the end that connects of tempering room pipe 31 is provided with annular flange 32; Annular flange 22 and annular flange 32 are connected by bolt, cause auxiliary air inlet plenum pipe and tempering room pipe to be joined and form the one pipe that is connected for connecting.Auxiliary air inlet plenum pipe 21 is provided with air inlet 5, and the other end of auxiliary air inlet plenum pipe 21 is provided with flange 20 and does the sealing connection, and the outlet of tempering room pipe 31 is set to the necking end 33 of convergence type.
When the utility model is regulated flue-gas temperature when needs; Through regulating the flow of the auxiliary air air inlet mouth of pipe 5; Cryogenic air is got in the tempering rooms 3 by auxiliary air inlet plenum 2 and with high-temperature flue gas after the port of export mixes, spray into again in the burner hearth, realize the purpose of reduction flue-gas temperature thus.The port of export of tempering room pipe 31 is set to the structure of reducing 33, its role is to regulate the spouting velocity and the flow of the flue gas after the cooling.
The utility model has not only been realized the purpose of adjustable fuel gas burner ejection flue-gas temperature; And overcome local burning and the unequal defective of heating-up temperature because of furnace temperature inequality and processed workpiece, satisfied the regulatory demand of different hot-working products simultaneously to flue-gas temperature.
