Description

Synthetic fuel burner device

The utility model relates to a kind of use fluid combustion utensil, specifically a kind of burner assembly that uses synthetic fuel.

The CN91207309.8 patent disclosure a kind of methanol fuel stove, burner wherein includes feed tube, the attaching nut, generating tube, the combustion chamber, air inlet pipe, parts such as air door and control valve constitute vaporization combustion system.But find that in use there are two problems in this stove and accessory, the one, it is abundant inadequately to burn, the unburned substrate concentration height of dissipation, if use synthesizing methanol fuel, then airborne methanol concentration is higher near the stove and accessory, toxic effect takes place.The 2nd, " asthma " phenomenon is arranged in the combustion process, promptly the air pressure instability of carburretion causes flame suddenly big or suddenly small, combustion instability, combustion heat value is under some influence.

The purpose of this utility model just provides a kind of burner assembly of strengthening vaporization effect, and the vaporization effect of liquid fuel is improved, and it is more stable, more abundant to burn.

The utility model is achieved in that in the burner that is made of parts such as feed tube, attaching nut, generating tube, combustion chamber, air inlet pipe, air door and control valves, generating tube is set to one group of form, wherein secondary generating tube and feed tube join, be coiled in the top of combustion chamber, three grades of generating tubes are straight tube, join with the secondary generating tube, be horizontally through the middle part, combustion chamber, level Four generating tube and three grades of generating tubes join, be looped around inner ring upper edge, combustion chamber, the exit of level Four generating tube is connected on the control valve.Like this, top, middle part and inner ring etc. that one group of generating tube has been arranged on the combustion chamber are located, and the vaporization pipeline prolongs, and the vaporization effect of fuel obviously strengthens, thereby makes burning more abundant, the basic ripple disable of air pressure, and it is more stable to burn, and has overcome " asthma " phenomenon.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is an outward appearance vertical view of the present utility model;

Fig. 2 is a structural representation of the present utility model.

As shown in Figure 1, 2, combustion chamber 7 is the tubular double Shell, the oblique two row's burner ports of leaving in top, a liquid dish 13 is fixed by support 14 in the bottom, and air inlet pipe 8 is led in the combustion chamber 7, be provided with air door 9 at the middle part of air inlet pipe 8, the air door driving lever 12 of the bottom by stirring air door 9, the size of control intake, the air inlet pipe end connects control valve 10, rotate the knob 11 on the control valve 10, but switch or adjusting air inflow.7 middle parts are horizontally through feed tube 1 in the combustion chamber, and synthetic fuel enters burner thus.This pipe has the effect of preheating and one-level vaporization concurrently.Feed tube 1 passes the part of combustion chamber 7 and connects secondary generating tube 3,4 by attaching nut 2.The secondary generating tube is an annular, 7 the top around the combustion chamber.This secondary generating tube is owing to be arranged on the top, combustion chamber, and nearest from burning things which may cause a fire disaster, vaporization effect is the most obvious.For further strengthening vaporization effect, the secondary generating tube can be made for twin nuclei, be divided into outer endless tube 3 and interior endless tube 4.Because the liquid contact surface of flat pipe is long-pending big, and heating surface area increases, and the outer endless tube 3 of secondary generating tube can be made for the flat tube form, makes fired vapour abundant for this reason, interior endless tube 4 still is the pipe form simultaneously.The exit of interior endless tube 4 is connected three grades of generating tubes 5 by the attaching nut.Three grades of generating tubes 5 are the straight tube form, are horizontally through from the middle part, combustion chamber, with lengthening vaporization pipeline, stablize air pressure.Rational in infrastructure for making, three grades of generating tubes 5 are the right-angled intersection form with feed tube 1.Level Four generating tube 6 is a ring pipe also, is arranged on 7 inner ring upper edges, combustion chamber, with close burning things which may cause a fire disaster.Its two exit all from the combustion chamber 7 bottoms draw, an end is communicated with three grades of generating tubes through the attaching nut, the other end is received on the control valve 10, is about to be transported to control valve through the gaseous fuel after whole level Four vaporizations, delivers to the combustion chamber internal combustion through air inlet pipe again.

The utility model is by being provided with level Four vaporization pipeline, liquefied synthetic fuel is vaporized fully, particularly for the synthesizing methanol fuel that contains big water gaging, because this vaporizes fully, feasible burning is very complete, substantially do not have residue dissipation, avoided the toxic and side effect of methyl alcohol, make the civil nature of synthesizing methanol fuel become possibility.Because vaporization is fully, and the pipeline revolution is many, make stable gas pressure to have overcome a common disadvantage-" asthma " phenomenon that has all kinds of synthetic fuel stove and accessorys now thus, make flameholding, and calorific value improves.
