Further, also comprise nozzle, said nozzle is arranged at the air ejector bottom, and the outlet of said gasifier is communicated with air ejector through nozzle;
Further, on the said air ejector inner chamber area of cross section greater than the inner chamber area of lower cross section;
Further, also comprise upper and lower opening and hollow housing, said gasifier and air ejector all are arranged in the housing;
Further, said air ejector comprises injector body and combustion head, and said combustion head is positioned at the injector bodies top and is connected with the injector body is detachable, and said fire hole is arranged on the combustion head;
Further, said gasifier is spiralling coil pipe, and the coil pipe lower nozzle is the inlet of gasifier, and upper orifice is the outlet of gasifier.
The beneficial effect of the utility model is: the utility model in use, liquid fuel gets into air ejector through fuel feed tube and gasifier, again the air admission hole inflow liquid-bearing pan through the air ejector bottom; At this moment igniting; Make its preheated burning, igniting back liquid fuel gasifies in gasifier soon, and then the entering air ejector is exactly the fuel gas that is gasified totally; And primary air is from the air admission hole suction of air ejector bottom; Fuel gas is with after primary air mixes, and the fire hole ejection burning from the air ejector top communicates with extraneous auxiliary air in the combustion process.
Therefore, the advantage of the utility model is:
1. the utility model can make the abundant gasification, and combustion of liquid fuel, and air ejector can also introduce air-breathing, need not by air blast combustion-supporting;
2. air ejector is according to the size of burning load; Can regulate amount of air drawn automatically, promptly when burning load increases, the proportional automatic increase of air ejector amount of air drawn; When burning load reduces, the proportional automatic minimizing of air ejector amount of air drawn; Even burning load is regulated than reaching 10, burner also can reach optimal air-fuel ratio all the time, and efficiency of combustion is high, flameholding;
3., use adaptive surface extensive as long as supply fuel to have the pressure of 0.05MPa just can realize normal combustion outward;
4. not producing carbon distribution in the burner stops up: because gasifier is spiralling coil pipe; Its heat exchange area is big, and gasification temperature adapts to, so gasifier is difficult for carbon distribution; And the gasifier runner has automatic cleaning function; Even carbon distribution is arranged once in a while, also can in combustion process, discharge smoothly, thus the fault of having avoided carbon distribution to stop up.
The utility model also is applicable to other liquid fuel except that being applicable to alcohol radical liquid fuel; The utility model is applicable in firing equipments such as Industrial Stoves, boiler or domestic stove and uses.
Description of drawings
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model is done further to describe in detail below, wherein:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below will be with reference to accompanying drawing, the preferred embodiment of the utility model is carried out detailed description.
Fig. 1 is the structural representation of the utility model, and is as shown in the figure, the liquid fuel instant gasification self adaptation air distribution burner of the utility model; Comprise gasifier 3, fuel feed tube 2 and liquid-bearing pan 1; Also comprise air ejector 7, said air ejector 7 tops are provided with fire hole 6, and the bottom is provided with air admission hole 9; The inlet of said gasifier 3 is communicated with fuel feed tube 2; Outlet is communicated with air ejector 7, and said air ejector 7 is arranged at gasifier 3 belows, and said liquid-bearing pan 1 is arranged at air ejector 7 belows; Liquid fuel gets into air ejector 7 through fuel feed tube 2 and gasifier 3; Air admission hole 9 through air ejector 7 bottoms flows into liquid-bearing pan 1 again, and at this moment igniting makes its preheated burning; The gasification in gasifier 3 soon of igniting back liquid fuel; And then what get into air ejector 7 is exactly the fuel gas that is gasified totally, and primary air sucks from the air admission hole 9 of air ejector 7 bottoms, and fuel gas is with after primary air mixes; Fire hole 6 ejection burnings from air ejector 7 tops communicate with extraneous auxiliary air in the combustion process; The primary air amount that air ejector 7 sucks during according to burning the vacuum magnitude of formation air ejector 7 in regulate automatically.
