Embodiment

Below in conjunction with drawings and Examples, the present invention will be described.

The utility model is applicable to the liquid fuel being easy to vaporize such as methyl alcohol one class, structure is as shown in Figure 1, mainly comprise 4 combustion chambers, pressing aid cover (5), air pressure closed tube (9), windshield (8), high-pressure connecting pipe (6), liquid fuel transfer lime (10), multiple high pressure bocca (11), fuel control valve (12), air input variable valve (15) etc. In the present embodiment, the first combustion chamber (1), volume is 6782 cubes of mm; Three, the 2nd combustion chamber (2) volume is 432000 cubes of mm the 3rd combustion chamber (3), and volume is 884530 cubes of mm the 4th combustion chamber (4), and volume is 6229760 cubes of mm.

Principle of work is as follows:

First the first combustion chamber is carried out preheating, the Pan Chu that about 10 ml methanol fluid drips enter high pressure bocca (11) is lighted, have significantly blue flame. flame was to the first combustion chamber (1) preheating about a minute, slowly open fuel control valve (12), a small amount of liquid is flowed into and in the first combustion chamber (1), carries out fission expansion generation high pressure, highly pressurised liquid sharply injects burning by high-pressure connecting pipe (9) to the 2nd combustion chamber (2), along with continuous liquid enters burning fission expansion far away, produce pressure difference and enter into the 3rd combustion chamber (3) burning by air pressure closed tube (6), entered second-compressed burning, thoroughly turn into gas that gaseous state produces High Temperature High Pressure via 12 high pressure boccas (11) from liquid state, injection thermal-flame carries out oxygenation combustion-supporting burning again to the 4th combustion chamber (4). through air high speed impact combustion-supporting, make methanol molecules microminiaturization, it is to increase the clean degree of gaseous combustion and temperature, thus make fuel combustion pure. decrease pollution, serve the function saving raw material, under high pressure the 4th combustion chamber (4) Thorough combustion, it is seen that flame outlet (7) has flame spraying to go out, and the flame after ejection about 1300 degree, lights a fire successfully. vaporizing after three times, pressure increases and jets out flames, and in inlet mouth (13), inlet mouth (14) defines low pressure area, and outside large quantity of air enters into the 4th combustion chamber (4) Thorough combustion.

Air input variable valve (15) can regulate air output, and the 4th combustion chamber (4) can be made when high temperature to make the more abundant of material combusting. Reach energy-conservation object, to 1 ton of boiler heating, consumption methyl alcohol per hour 50 kilograms. serve energy-conserving action. Cut charging motor and air supply motor simultaneously, reduce cost, not power consumption. Compare with existing combustion engine and saved energy half. Solve above-mentioned defect, it is achieved that the real meaning of methyl alcohol energy-saving burner, decreases atmospheric pollution.

When processing and manufacturing methyl alcohol energy-saving burner, raw material, instrument to be got ready. Material with stainless steel (304A), the sheet material that 6mm is thick. With Stainless steel 316 L diameter 22mm diameter 25mm two kinds of tubing. Instrument argon welder. Artificial according to above-mentioned size forming process firm welding. Requiring the first combustion chamber (1), after the 2nd combustion chamber, combustion chamber (2) the 3rd (3) welding is good, pressure testing 16 pressure are as well air tight. Then on the 3rd combustion chamber (3), the hole of 2.5mmx12 is bored with electric hand drill. See the high pressure bocca (11) of Fig. 2. Even if energy-saving burner manufactures successfully. Operation can be carried out employ according to above-mentioned. Have easy and simple to handle, according to the success of above-mentioned steps handling ease. Be conducive to promoting.
