Abstract
The invention relates to a wide flame stabilization burning head for a gas burner. The wide flame stabilization burning head for the gas burner comprises a flame tube, a mixing section, a rotational flow flame stabilizer and a gas distribution plate. The mixing section, the gas distribution plate, the rotational flow flame stabilizer and the flame tube are arranged coaxially; and the mixing section adopts three spaced coaxial cavities. The burning head having the structure adopts an annular cavity structure, so the gas and the combustion air are mixed fully to guarantee the completeness of burning and to realize a wide fire power adjusting range (up to 1: 8); moreover, the burning head has a wide gas heat value application range, namely the gas sources such as natural gas, petroleum gas and the like can be well burned from a gas source such as straw gas having a low-level heat value of about 1, 300 kCal/Nm<3> to a gas source having a high heat value.
Description
Technical field
The present invention relates to a kind of combustion head that is used for the automatic gas burner, relate in particular to the wide steady flame combustion head that a kind of gas burner is used.
Background technology
At present, the automatic gas burner is to different combustion gas designs combustion head suitable with it, in case the combustion gas kind changes or designs the fuel gases calorific value fluctuation and strengthen, will be unwell to burning; And these combustion head firepower adjustable ranges are smaller, are generally 1: 2～1: 4, are difficult to satisfy the requirement of industrial furnace to heat tracing technology.Energy-conserving and environment-protective are China's state basic policies, and the use of low-grade gas gets more and more in fuel gas with low heat value and the air mixture etc., and existing combustion head to the high-grade combustion gas can not adapt to this variation.
Summary of the invention
The objective of the invention is to realize the combustion head of wide thermal value range fuel gas buring for solving the problems of the technologies described above design a kind of under steady flame border than broad.
The technical problem that (1) will solve
The related combustion head of the present invention adopts the particular structure form, realizes that the firepower adjustable range is wide, up to 1: 8; It is wide to be suitable for the fuel gases calorific value scope, from low heat value source of the gas such as stalk gas (Lower heat value 1300kCal/Nm
3About) to high heating value source of the gas such as natural gas, oil gas etc.
(2) technical scheme
The present invention adopts ring cavity structure combustion head, forms once and the secondary combustion mixture, adopts technical measures such as strong eddy flow simultaneously, and realize through following technical scheme:
The wide steady flame combustion head that the present invention uses for a kind of gas burner; This combustion head comprises burner inner liner, blending section, eddy flow flame holder, air distribution disk etc.: blending section, air distribution disk, eddy flow flame holder and burner inner liner coaxial arrangement; The blending section adopts coaxial three cavities of separating; The intermediate annular cavity is walked in combustion gas; Combustion air is walked interior ring, outer shroud cavity, and outer shroud has the air spoiler.Blending is carried out in the combustion air of interior ring passage and the combustion gas that the air distribution disk orifice flow goes out, and forms one time combustion mixture; The combustion air of outer ring channel mixes formation secondary combustion mixture after through the spoiler flow-disturbing with the master of air distribution disk place gas-flow; Above-mentioned once, the secondary combustion mixture flow through the eddy flow flame holder once more after the blending by ignition combustion.
Compared with prior art, the invention has the beneficial effects as follows: adopt the ring cavity structure, form once, the secondary combustion mixture, one time combustion mixture forms bigger recirculating zone behind the eddy flow flame holder, realizes the wide steady flame border of burning; The secondary combustion mixture is tissue burning behind the eddy flow flame holder in than the gas concentration scope of broad, realizes firepower adjustable range wide (up to 1: 8), and suitable fuel gases calorific value scope is wide (from low heat value source of the gas such as stalk gas (Lower heat value 1300kCal/Nm
3About) but to high heating value source of the gas such as natural gas, oil gas etc. good combustion all).

The specific embodiment
Visible by Fig. 1: that blending section (1), group section (2), spoiler (3), air distribution disk (4), eddy flow flame holder (5) and burner inner liner (6) etc. are installed on combustion head; On the combustion head axis direction, blending section (1), group section (2), spoiler (3), air distribution disk (4), eddy flow flame holder (5) and burner inner liner (6) coaxial arrangement, burner inner liner (6) is in the outside, and group section (2) is in the centre, and blending section (1) is in the inboard; Burner inner liner (6) is adjustable through group section (2) with respect to the distance of eddy flow flame holder (5), and eddy flow flame holder (5) is adjustable with respect to the distance of air distribution disk (4); Blending section (1) is a ring cavity formula structure, is made up of three different-diameter steel pipes etc., forms three annular cavities, and middle cavity is walked combustion gas (9), and the inner and outer rings cavity is walked combustion air (10); Blending section (1) outer shroud has a circle spoiler (3), and lower exit has an air distribution disk (4), and air distribution disk has numerous fumaroles on (4), and the hole of inside ring cavity road spray is arranged, and the hole of spray is downstream also arranged.
Described burner inner liner (6) is installed on the group section (2), and air distribution disk (4) is installed in the burner inner liner (6) with eddy flow flame holder (5), ignitor (7) and flame detecting electrode (8).
Blending is carried out in the combustion gas that the combustion air in the interior ring cavity of blending section (1) road and air distribution disk (4) orifice flow go out, and forms one time combustion mixture; Locate main gas-flow with air distribution disk (4) behind combustion air process spoiler (3) flow-disturbing of outer shroud cavity and mix formation secondary combustion mixture; Once, the secondary combustion mixture flow through eddy flow flame holder (5) once more after the blending by ignition.Ignitor (7) draws electric arc to light combustion mixture one time to eddy flow flame holder (5), forms stable flame in eddy flow flame holder (5) back, and flame detecting electrode (8) carries out dynamic monitoring to flame.
