Description

The vertical burner of gas burner

Technical field

The utility model relates to a kind of and the matching used vertical burner of gas burner.

Background technology

The combustion head that is used at present the industrial combustion gas burner both at home and abroad mostly adopts with burner body makes integral structure, and its combustion head is horizontal flame mode.Though compact conformation, the volume of this kind gas burner are little.But its such gas burner only can with gas fired-boiler and the supporting use of kiln, purposes is very single.And can not with coal-burning boiler and the supporting use of kiln, the transformation of existing coal-burning boiler of particularly inapplicable China and kiln is used.Simultaneously because such burner adopts horizontal flame mode, when its burning, heating, the thermal current of the burning that it is heated moves upward, and move downward greater than the fuel gas of air specific weight, make burning gases not burn fully, caused the waste of the gas energy, especially select the fuel gas of combustion gas gas self proportion for use greater than air specific weight, more outstanding as liquefied petroleum gas etc., cause the bigger waste of the gas energy.

Summary of the invention

The purpose of this utility model is to provide a kind of efficiency of combustion height, can and adapts to vertical burner of various structure coal-burning boilers with the supporting use of burner.

The purpose of this utility model is achieved in that the vertical burner of this gas burner is made up of combustion head and the wind conveying pipe that is communicated with combustion head, major-minor appendix and igniter head of being assemblied in the combustion head, longitudinal angle between described wind conveying pipe and combustion head bocca is 30 °-170 °, and being connected to the wind conveying pipe on the combustion head and the horizontal-extending length of major-minor appendix is 0.5-3 rice.

Described combustion head is made up of combustion head housing, major-minor air chamber, combustion gas and igniting appendix and cyclone, described major-minor air chamber is located at the bottom of burning chamber shell, constitute a general mood mixing chamber in the burning chamber shell on major-minor air chamber top, combustion gas appendix that is communicated with the major-minor air chamber and igniting appendix are assemblied in respectively in the general mood mixing chamber, and cyclone is assemblied in the top of igniting appendix.

Described wind conveying pipe and major-minor appendix are a pair of corner structure, and its lateral duct that is connected with combustion head is long to be 0.5-3 rice, and the vertical pipeline that links to each other with lateral duct is long to be 0.5-2 rice.

The technological progress that the utility model is obtained is: 1, this vertical burner adopts the combustion system of vertical flame, fuel gas is under the effect of blast during its work, fuel gas remains motion mode upwards, in being located at combustion head, under the effect of cyclone, make fuel gas be in burning under the mixed combustion state all the time simultaneously.Thereby burning gases can be burnt fully.Can light the fired state burning down that body always is in fully, stablizes mixing no matter promptly adopt the fuel gas of any kind of all can make, burning gases are fully burned.Thereby not only improved boiler thermal output effectively, also saved the energy greatly, reduced environmental pollution.2, the combustion head of this burner adopts the mode of vertically burning and lengthening gas transmission, air-supply pipeline, not only combustion head can be placed burning position best in the boiler, and its combustion efficiency is further enhanced.The also transformation of the coal-burning boiler of applicable various structure types and existing coal-burning boiler, thus for the coal of existing boiler changes the enforcement of gas, provide a kind of comparatively desirable technical scheme.3, because the combustion head of this device adopts the flame mode that vertically makes progress, upwards the combustion flame that sprays is under the resistance of inwall on the boiler, can change the direction of motion of combustion flame, make combustion flame form a kind of combustion system of outside diffuse transmission type at the internal ring wall of boiler, this kind combustion system has not only increased the flame burning area effectively, the burning gases that make are burnt more fully, and efficiency of combustion has obtained further raising.

The specific embodiment

Be that embodiment further specifies the utility model below with the accompanying drawing, as shown in Figure 1, the vertical burner of this gas burner is by combustion head 1 and the wind conveying pipe 2 that is communicated with combustion head, major-minor appendix 3,4 and igniter head 5 of being assemblied in the combustion head 1 form, angle between described combustion head 1 and wind conveying pipe is (30 °-170 °), the selected angle of present embodiment is 90 °, this angle can also can be adjusted at 30 °-170 ° according to the concrete condition in boiler furnace space, general this angle is less than 45 ° or greater than 170 °, and the gas of its burning can not be very sufficient burned.For with the supporting use of the boiler of existing structure, especially for transformation to existing coal-burning boiler, be that coal burning boiler is transformed into gas boiler, on the basis that does not change existing boiler structure, the wind conveying pipe 2 and the major-minor appendix 3 that need will be connected with combustion head 1,4 pipeline length horizontal-extending is a 0.5-3 rice, its concrete pipeline length will be determined according to supporting with it boiler structure, simultaneously for make burner convenient with the supporting use of coal-burning boiler, particularly to having the transformation of coal-burning boiler now, also need wind conveying pipe 2 and major-minor tracheae 3,4 are designed to the crutches corner structure, wind conveying pipe 2 that is connected with combustion head and major-minor tracheae 3,4 horizontal expansion pipeline length is being between the 0.5-3 rice generally, wind conveying pipe 2 that links to each other with lateral duct and major-minor tracheae 3, vertical pipeline length of 4 is generally between the 0.5-2 rice.From the horizontal length between vertical pipeline and burner, determine according to the concrete structure of boiler and the installation site of burner together with pipeline.Above-mentioned said combustion head 1 is by combustion head housing 6, major-minor air chamber 7,8, combustion gas and igniting appendix 9,10 and cyclone 11 form, this present embodiment of profile of described combustion head housing 6 is a column structure, be provided with and major-minor tracheae 3 in the bottom of combustion head housing 6, the 4 major-minor air chambers 7 that are communicated with, 8, major-minor air chamber 7, inner cavity chamber's formation-general mood mixing chamber of the burning chamber shell 6 on 8 tops, the bottom of mixing chamber is provided with the air inlet that is communicated with wind conveying pipe 2, described be communicated with main gas tank 7 light the appendix 10 uniform internal ring wall peripheries that are arranged in burning chamber shell 6, the upper end of its every combustion gas appendix 10 is provided with gas ejection ports.The described igniting appendix 9 that is communicated with accessory air-space 8 is located at the middle part in the burning chamber shell 6, and its cyclone 11 is assemblied in the top of igniting appendix 9, and the upper end of igniting appendix 9 is provided with the ignition gas jet.Igniter head 5 is installed in the corresponding mutually top of igniting appendix 9 puff prots.
