CN2182343Y - Core of liquid fuel automatic evaporation burner - Google Patents

Abstract

The utility model relates to a new core of liquid fuel automatic evaporation burner, which is mainly composed of a burning chamber, an evaporation chamber, a spiral evaporation tube, a gas storage chamber, an automatic pressure tube, a liquid inlet tube, etc. When the liquid inlet tube connected with a fuel tank is used for leading liquid, evaporation generated in the evaporation chamber increases the pressure of the fuel tank and liquid inlet amount is enlarged. On the other hand, fuel liquid after evaporation passing across the evaporation tube, the gas storing tube, a gas guiding tube, a control valve and an injection tube is ejected in an air and gas mixture tube and mixes with the air, and then enters the burning chamber; a flame is ejected. The utility model has the advantages of simple structure and convenient maintenance. When the utility model is used for replacing the core of the existing evaporation burner, the pre-heating time is shortened by 20%; the heating efficiency is improved by 10 percentage points; the general manufacture cost is lowered by 20%; the service life is improved by more than one time.

Description

Core of liquid fuel automatic evaporation burner

The utility model is a kind of home-use novel liquid fuel gasification burner combustion chamber.

In the prior art, to utilize the regenerated heat source is that the vaporizing liquid stove and accessory of fuel is a lot of, wherein comparatively advanced with the stove and accessory of automatic vaporized liquid fuel, as present " orchid board " gas burning range of being produced by Wuhan factory that has gone on the market is exactly a kind of preferably, the people's lives that the appearance of this product gives those shorts of electricity, lack the bavin area have solved many problems really, also give simultaneously such as methyl alcohol, the recycling that contains industrial combustible waste gases waste liquids such as assorted toxic ethanol advantage is provided.But the combustion chamber of this cooking stove is to connect extremely with tubular hollow vaporizer and spiral shell shape generating tube, and combustion chamber and vaporizer connect dead, not only fabrication and installation difficulty, keep in repair constant, the cost height, accident is many, the vapour pressure shakiness often occurs and causes " breathing ", the air door tempering, burst is flashed, and phenomenon such as little when big during fiery flute gives to manipulate to bring inconvenience and the thermal efficiency of fuel is descended, damage parts too early, shorten the problems such as service life of whole cooking stove.

The purpose of this utility model will propose a kind of simple in structure exactly, and installation and maintenance are convenient, and vapour pressure is stable, the flare equilibrium, and thermal efficiency height, the combustion chamber of the automatic gasification burner of novel liquid fuel of long service life is to overcome the deficiencies in the prior art.

This automatic gasification burner combustion chamber that the utility model proposes, the same combustion chamber that the band burner port is arranged with existing combustion chamber, vaporizer, the spirality generating tube, the automatic automatic forcing pipe of feed tube, combustion vapour conduit and combustion vapour control valve, be combustion chamber and vaporizer, the spirality generating tube does not connect extremely mutually, and be provided with the steam receiver of a stable and buffering vapour pressure in the vaporizer bottom, spirality generating tube one end and vaporizer top are connected, the other end and steam receiver are connected, automatically the forcing pipe two ends are connected with closed tank and vaporizer respectively, automatically the feed tube two ends are connected with closed tank bottom and vaporizer bottom respectively, combustion vapour conduit two ends are connected with steam receiver and combustion vapour control valve respectively, vaporizer and steam receiver are being overlapped in the combustion chamber, one air is arranged on its exterior wall, combustion vapour mixing tube, the combustion vapour playpipe that is being connected with combustion vapour control valve inserts in this pipe, and this pipe and combustion chamber are connected with tangential direction.

In order to start gasification burner work, this combustion chamber bottom is provided with a preheating dish, can adorn small amount of liquid fuel in the dish, and that lights can be earlier with the required pressure of vaporizing liquid generation work in the vaporizer.

The utility model has the advantages that conspicuously, at first is that combustion chamber and vaporizer are independent separately, makes easy for installationly, works as vaporizer, when the spirality generating tube burns out, changes and keeps in repair all very convenient.Next is to set up a steam receiver to have cushioned the vapour pressure fluctuation that causes owing to various disturbance factors in the system between spirality generating tube and combustion vapour conduit, makes the steam flow that sprays in the combustion chamber stable, flare equilibrium, thereby thermal efficiency height, and working stability uses easy to operate.

Further describe the utility model below in conjunction with accompanying drawing and example.

Accompanying drawing 1 is front view of the present utility model (normal cross-section).

Accompanying drawing 2 is the utility model vertical views.

Accompanying drawing 3 is the utility model steam receiver front views (normal cross-section).

Accompanying drawing 4 is the utility model steam receiver vertical views.

Shown in Fig. 1-4.The air of combustion chamber (8) and disjunctor, combustion vapour mixing tube (9) adopt common iron plate and steel pipe manufacturing, both connected modes are ditto described, just top, chamber, combustion chamber sets out (5) 40 of fire holes (accompanying drawing does not all draw), wherein 8 of inclined side, 32 at top, angle is at 45 mutually, spirality generating tube (6) and steam receiver (4) and the fire output hole opened three encloses totally 15, the vaporization so that liquid fuel can fully be heated after entering vaporizer are arranged facing to vaporizer (7) at the burning inwall.Air, combustion vapour mixing tube have a horn mouth and are convenient to be installed into air valve simultaneously so that air is brought into, the control intake.Vaporizer, spirality generating tube, steam receiver, automatic feed tube (2), automatic forcing pipe (1), combustion vapour conduit (11) and combustion vapour playpipe (10) all adopt heat-resisting and antioxygenic property copper product manufacturing preferably.Be the hollow circular ring that is shaped as of steam receiver easy for installation, ring diameter and vaporizer equal diameters in it.Combustion vapour control valve (12) and its regulating handle (13) etc. are on the sort of cooking stove above-mentioned employed.Preheating dish (3) is made of iron sheet.

In addition, automatically feed tube and the closed tank that is used of forcing pipe and the utility model automatically, table, and the discrepancy in elevation configuration of fuel tank and vaporizer etc. concerns and above-mentioned " orchid board " cooking stove identical or similar.

When this combustion chamber is used for replacing " orchid board " cooking stove combustion chamber and uses equal fuel, shorten 20% preheating time, the thermal efficiency has improved 10 percentage points, and vapour pressure is stable, the flare equilibrium, comprehensive manufacturing cost descends more than 20%, and does not advance the fire tube tempering phenomenon, has prolonged service life more than 1 times.
