Description

Methanol burner multiinjector seat air-cone

Technical field:

A kind of methanol burner multiinjector seat air-cone, by many fire jetting holes steady dish of windy type, comprehensive support, multiinjector seat Centring ring, many nozzle holders, high tension spark protection set, lighter composition；Belong to thermal technology's mechanical field, be suitable for the combustion of high-power methanol Burning machine adapted.

Background technology:

The various boilers of China's enormous amount, burning machine for furnace are many with diesel oil or kerosene as fuel, along with energy resource structure Adjust and the expansion of pollution control work, there is the methanol fuel resources advantage with himself of strategic value, price advantage, ring Guarantor's advantage progressively becomes energy new lover, but traditional liquid combustor does not adapt to the use requirement of methanol fuel at present, especially The large-scale combustor of 3000000 kilocalories to 20,000,000 kilocalorie loads, inadaptable because of deposit structurally, not only burn not with environment-friendly methanol Go out the effect of environmental protection, go back serious environment pollution, there is also de-fire, misfire, the problems such as combustion conditions is poor, and degree of amplitude modulation is little. This utility model aims at these problems of solution and arranges.Using environment-friendly methanol can accomplish not take off fire, Wind-oil ratio degree of amplitude modulation is big, wind Oil good mixing, combustibility is very good, the many deficiencies before overcoming, and equipped high-power methanol burner can show Outstanding operating condition.

Utility model content:

1, many fire jetting holes windy type stable flame pan, is become with outer round straight hole disc set by inner circle R-joining disk.Relatively traditional steady flame The advantage of dish is: stable flame pan can be made many fire jetting holes by A., can install and organize nozzle holder more, can meet high-power combustor and make With the requirement of methanol；B., " one " font 3 nozzle holder, " star " type 4 nozzle holder, " ten " word nozzle holder can be installed；C. many sprays Fire hole windy type stable flame pan possesses rotation and two kinds of wind types of direct projection, can make wind oil good mixing, and flame root is from stable flame pan face Closely, making flame stabilization, not de-fire, it is big that wind oil adjusts amplitude；

2, comprehensive support: be made up of, than tradition circular steel ring, multiinjector seat, centring ring, stable flame pan support, fixed screw For simple function support, advantage is: A. can install many fire jetting holes windy type stable flame pan；B., multiinjector seat can be installed；C. can Be fixed in combustor round iron bucket and can before and after adjustment；D. can separate with multiinjector seat main body and position, convenient maintenance；G. can join Fill high-power combustor；

3, multiinjector centring ring: multiple circular iron rings are welded on comprehensive support, and igniting centring ring is semicircle, it is simple to band The nozzle carrier of lighter passes, and through nozzle holder in centring ring, both can position, and can become again support, facilitate nozzle holder master The dismounting maintenance of body；

4, many nozzle holders: be processed into toroidal with round copper rod, have multiple atomizer silk hole, the multiple atomizer of twist-on, Can twist-on 1.2.3.4.5.6 atomizer, there are a fuel feeding pipe thread hole, twist-on fuel feed pump in other end.Can be according to combustor power Size is equipped with corresponding nozzle holder, can be equipped with single seat, two-seater, 3,4,5 etc., so can make methanol burner Power accomplishes more than 20,000,000 kilocalories；

5, high tension spark protection set: cover " 7 " font semicircle iron plate on ceramic igniter, so can stop that high wind blows Vanishing point fire high tension spark, it is ensured that ignition success rate.

Technical scheme:

Methanol calorific value is low is the half of petrol and diesel oil, therefore fuel delivery than petrol and diesel oil many a times, thus need to increase atomizer Number, many of high-power machine atomizer number up to 6-20, it is contemplated that wind oil premix degree, flame holding, degree of amplitude modulation, flammability Energy, power load etc., it is impossible to too much atomizer is concentrated on a nozzle holder, therefore arrange:

1, arrange many fire jetting holes windy type stable flame pan, R-joining in rotating, stable flame pan and the outer stable flame pan of straight air holes form, root According to the number of nozzle holder, offering corresponding fire jetting hole on interior stable flame pan, interior stable flame pan rotary wind is beneficial to wind oil mixed combustion, Outer stable flame pan straight type bellows chamber wraps up in rotary wind, makes flame thrust advance, and stability is good, and not de-fire, combustibility is good, and wind oil is adjusted View picture degree is big；

2, arranging comprehensive support, one, support is circular steel ring, and the uniform fixed screw holes of steel ring, in order to be fixed on combustor On inner cylinder, support intermediate distribution has fuel feed pump centring ring, nozzle holder centring ring and stable flame pan support, in order to accept many flame Hole windy type stable flame pan, many nozzle holders and fuel feed pump；

3, arranging many nozzle holders centring ring, point (4) circle and (5) are enclosed, and (4.5) circle internal diameter is identical, are circular steel ring, (4) lap welding is connected on comprehensive support, and (5) circle is fixed on nozzle holder and leans on fuel feeding pipe end, and the nozzle holder with ring for fixing (5) is worn Cross (4) circle and become an adult, make nozzle holder main body be easy to dismounting maintenance；

4, many nozzle holders are set, the circle copper rod processing of many nozzle holders, determine copper rod size according to twist-on atomizer number, Nozzle holder one opens a fuel feeding pipe thread hole, twist-on fuel feed pump, and multiple atomizer silk hole is opened in other end, and twist-on atomizer can Twist-on 1.2.3.4.5.6 atomizer, multiple nozzle holders are assembled into one at a certain distance, are the fuel injector of different capacity, Nozzle holder can be assembled into center single seat, " one " font 3,4, " Flos Mume " type, " ten " font 5 etc.；

5, high tension spark protection set is set, ceramic igniter covers " 7 " font semicircle iron plate, so can stop strong Wind vanishing point fire high tension spark, it is ensured that ignition success rate.
