Abstract

The utility model relates to a gasifying stove. The outer wall of the sandwich layer ring (a vaporization chamber) of the stove head is provided with a circular current guiding space which is used as a burning chamber; the circular current guiding space is communicated with an ejector; in addition, a fire dividing cover positioned at the end surface of the stove head adopts a double-ring layer cover; the inner ring layer is arranged at the end surface of the vaporization chamber and is inward sloped. As the arrangement of the burning chamber, gas with a certain heat from the ejector conducts preheating to liquid through the vaporization chamber; in addition, the cover of the inner ring lay of the fire dividing cover can replenish a certain heat source to the vaporization chamber, which keeps operation stable. The utility model has the advantages of stable burning, high flame stability, short flame, strong fire power, complete vaporization, safe burning, etc.

Description

Gasifying stove

The utility model relates to a kind of stove and accessory, particularly a kind of gasification furnace.

Chinese patent application numbers 94226230.1 discloses a kind of gasification furnace, it is characterized in that interlayer circle (being vaporizer) the outer wall upper end at burner is provided with an annular water conservancy diversion funnel, the wind vent places annular water conservancy diversion funnel upper end, and a press pump is arranged in the fuel reserve tank, and the press pump delivery outlet is connected to burner preheating dish.This design can make the gas in the burner hearth limit the quantity of from the ejection of wind fire hole with maximum, has increased heat, has improved benefit.But, owing to leave burning things which may cause a fire disaster in the burner hearth, as the work thermal source of gasification, in the regular event process, not only wasted fuel and heat, and owing to it changes with duty, cause fuel tank pressure to raise, flame occurs from fire, takes off fiery phenomenon, and work is stable inadequately.

The purpose of this utility model is at above-mentioned deficiency, proposes a kind of improved gasification furnace, its tool flameholding, flame stability height, the characteristics that flame is short, firepower is strong, gasification fully reaches combustion completion.

The utility model comprises fuel reserve tank, fluid balance pipe, interlayer circle (vaporizer), burner, preheating dish, switch, gas output tube, gas equalizing line, press pump, it is characterized in that at burner interlayer circle (being vaporizer) outer wall one annular diversion space being set, its annular diversion space connects in injector; Divide skull to adopt double-deck circle, it is skewed that its inner ring inwardly is; The angle of inclination is good with 60 degree.

Now in conjunction with the accompanying drawings the utility model is further described:

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is that the A of accompanying drawing 1 is to view.

As shown in drawings, the utility model is by a minute fire lid 1, vaporizer 2, gas output tube 3, gas control valve 4, press pump 5, igniter support 6, nut 7, nozzle 8, air regulating board 9, injector 10, liquid output pump 11, igniting pin 12, preheating dish 13, fluid balance pipe 14, gas equalizing line 15, liquid feeding valve opening 16, fuel tank 17, switch 18 is formed, it is provided with an annular diversion space 19 as the combustion chamber at vaporizer 2 outer walls, annular diversion space 19 connects with injector 10, divide fire lid 1 to be double-deck circle, last ring layer is same as the prior art, following ring layer inwardly is skewed, place vaporizer 2 end faces, the angle of inclination is good with 60 degree.

During work, gaseous fuel with certain pressure (preheating generation) sprays from nozzle with certain speed, enter the shrinkage type air intake duct, and bring primary air into by the suction volume effect of fuel jet, fuel mixes in injector with air, is functional shift the pressure energy, fire hole is discharged from the head then, and from ambient atmosphere, obtain auxiliary air, finish combustion process, because annular diversion space 19 is as the setting of combustion chamber, the gas with certain heat of being come by injector with heat transferred vaporizer 2, carries out preheating to the liquid in the vaporizer 2 by the combustion chamber; In addition, be double-deck circle lid owing to divide fire lid 1, inner layer places vaporizer 2 end faces, inwardly is skewed, so in combustion process, have a certain amount of thermal source to lead lid by inner ring and enter vaporizer 2, makes the system stability continuous firing; Inner layer angle of inclination 60 degree in vaporizer 2 are the best.

Design of the present utility model has the flame temperature height, flame is short, firepower is strong, the characteristics of sufficient combustion, and the inside and outside awl of flame is clearly demarcated.

Claims

1, a kind of gasification furnace, comprise that fuel reserve tank, fluid balance pipe, vaporizer, burner, burner divide fire lid, preheating dish, gas equalizing line, injector, press pump, switch etc., it is characterized in that being provided with an annular diversion space 19 at the vaporizer outer wall of burner, annular diversion space 19 connects with injector.

2, a kind of gasification furnace according to claim 1 is characterized in that described burner divides the fire lid to be two ring layer lids, and the inner layer bezel ring, places the vaporizer end face, and tilts in vaporizer.

3, a kind of gasification furnace according to claim 2 is characterized in that it is 60 degree that described burner divides the optimum tilt angle of the inner layer lid of fire lid.
