Description
Technical field:
The present invention relates to the gas furnace equipment technical field, refer in particular to a kind of liquid-fuel burner.
Background technology:
The gas furnace of using in existing family expenses or the catering industry is a fuel with liquefied gas or natural gas mainly, and alcohol radical liquid fuel is a kind of emerging fuel of recent popularization.The fuel value of alcohol radical liquid fuel and liquefied gas, diesel oil are suitable, can be used as the alternative fuel of oil liquefied gas and fuel diesel, at a low price, safety, burning thoroughly, conveniently have at the bottom of no residue raffinate, the no blacking pan, have that sanitation and hygiene, safety, cheapness, raw material are easily purchased, characteristics such as easy to use, belong to the biomass clean energy of national encourage growth.
Because alcohol radical liquid fuel is liquid before burning, for improving fuel efficiency, must convert thereof into gaseous state.The mode of existing alcohol radical liquid fuel vaporization mainly is the mode by chemical reaction, and chemical reactions such as cracking take place under the effect of catalyst alcohol radical liquid fuel, forms fuel gas.Chinese patent 200510002482.5 disclosed alcohol group liquid fuel burners etc. for example.Obviously, this mode is the cost height not only, and the design of burner is also more complicated loaded down with trivial details, therefore is unfavorable for civilian popularization.
Summary of the invention:
The objective of the invention is to overcome the above-mentioned weak point of prior art, a kind of liquid-fuel burner that utilizes the fuel combustion waste heat to make liquid fuel evaporation is provided.
The present invention realizes that the technical scheme that its purpose adopts is: a kind of liquid-fuel burner, comprise gas generator and bocca, described gas generator is an airtight ring-type vaporizer, the external annulus of described gas generator offers liquid fuel inlet and gas outlet respectively, described gas outlet is connected with the fuel gas inlet of described bocca by gas pipeline, and described bocca is limited in the interior ring center of described gas generator.
In the technique scheme, the liquid fuel of described gas generator inlet is connected with infusion pump by liquid-transport pipe-line.
In the technique scheme, the bottom of described gas generator is provided with some legs.
In the technique scheme, described bocca has a spit tube body, the fuel gas inlet of described spit tube body is arranged on the sidewall of bottom, the port peripheral hardware of giving vent to anger in described spit tube body has an end face compressing tablet, described end face compressing tablet is arranged on the bolt, described bolt be arranged on being threaded of described spit tube body bottom face; And the end face of the described port of giving vent to anger is provided with some jet grooves.
In the technique scheme, banking stop is arranged in the outer periphery of described spit tube body.
After the present invention adopts technique scheme, gas generator is the periphery that airtight ring-type vaporizer is positioned at bocca, during bocca ejection fuel gas buring, flame thermal radiation can be directly to the internal ring wall heating of vaporizer, its temperature is raise, thereby the burning needs are satisfied in the vaporization of the liquid fuel in the aggravation vaporizer.Therefore the carburretion process of the utility model burner is more direct quick, need not to adopt catalyst etc., can save cost; The utility model is simple in structure simultaneously, can make full use of the waste heat of fuel combustion, avoids heat waste, improves the heat energy utilization rate, plays the good energy-conservation environmental protection effect.
Description of drawings:
Fig. 1 is a cutaway view of the present invention;
Fig. 2 is a stereogram of the present invention;
Fig. 3 is a plan structure schematic diagram of the present invention;
Fig. 4 is the structural representation of bocca of the present invention.
The specific embodiment:
The invention will be further described below in conjunction with specific embodiments and the drawings.
As shown in Figure 1, 2, 3, liquid-fuel burner of the present invention mainly comprises gas generator 1 and bocca 2, and described gas generator 1 is an airtight ring-type vaporizer, and cross section is annular.That this gas generator 1 adopts is thicker, thermal conductivity preferred metal material for example iron and steel make, can bear enough pressure.
The external annulus of described gas generator 1 offers liquid fuel inlet 11 and gas outlet 12 respectively, and described liquid fuel inlet 11 is connected with infusion pump 5 by liquid-transport pipe-line 4.Described gas outlet 12 is connected with the fuel gas inlet 211 of described bocca 2 by gas pipeline 3, and described bocca 2 is limited in the interior ring center of described gas generator 1, gas pipeline 3 is bent to its bottom downwards from the outer wall of gas generator 1, and bending inwards is connected with the fuel gas inlet 211 of the bocca 2 that is positioned at gas generator 1 ring center again.
After adopting said structure, to enter the ring-type vaporizer be in the gas generator 1 to liquid fuel entering the mouth 11 from liquid fuel through liquid-transport pipe-line 4 under the effect of infusion pump 5, when not lighting a fire, because liquid fuel also can be vaporized at normal temperatures, therefore there is fuel gas to exist in the vaporizer, fuel gas is entered in the bocca 2 by gas pipeline 3 by gas outlet 12, and can light a fire and take fire this moment; In the combustion process, bocca 2 combustion flames produce heat radiation to the internal ring wall of the gas generator 1 of periphery, its temperature is raise fast, thereby the liquid fuel in the vaporizer is heated, aggravate its vaporescence, accelerate the generation of fuel gas, thereby provide combustion gas to bocca 2 continuously.
The bottom of described gas generator 1 is provided with some legs 13, is convenient to the installation or the layout of burner, and provides for gas pipeline 3 and pass through the gap.
Again as shown in Figure 4, in the present embodiment, described bocca 2 has a spit tube body 21, the fuel gas inlet 211 of described spit tube body 21 is arranged on the sidewall of bottom, outside the port 212 of giving vent to anger of described spit tube body 21, be provided with an end face compressing tablet 22, described end face compressing tablet 22 is arranged on the bolt 23, and described bolt 23 is connected with the screw thread 2130 that is arranged on described spit tube body 21 bottom faces 213; And described end face of giving vent to anger port 212 is provided with some jet grooves 2120.
Outer periphery in described spit tube body 21 has banking stop 24, so that bocca 2 integral body are limited to the center of gas generator 1, avoid taking place skew and causes ill effects such as flame heat is not in place.
End face compressing tablet 22 in the described bocca 2 adopts the higher heat proof material of thermal coefficient of expansion to make, and at the igniting initial stage, end face compressing tablet 22 temperature are lower, it is limited to expand, therefore end face compressing tablet 22 is bigger with the space of port 212 end faces of giving vent to anger, and give vent to anger slower this moment, and the firepower of bocca 2 is less; Along with the carrying out of burning, end face compressing tablet 22 temperature raise gradually, and volumetric expansion makes end face compressing tablet 22 more and more littler with the gap of port 212 end faces of giving vent to anger, and under the identical admission pressure, jet velocity is obviously accelerated, thereby the firepower of bocca 2 is increased until stable.Present embodiment bocca simple in structure, easy to assembly, cost of manufacture is low.Certainly, gas generator described in the utility model also can cooperate other forms of bocca to use.
Being connected between various pipelines and gas generator and the bocca can be adopted welding among the present invention, also can adopt mode such as be threaded, and pipeline can be independent pipeline, also can be the pipeline that many pipelines are formed by connecting; In addition, described liquid-fuel burner makes the core component of burner, and it can be used as burner and directly uses; Obviously in concrete practice; usually can increase servicing units such as igniter, control valve, burner housing; so that people use; and this also is this area customary means; therefore; even if on basis of the present utility model, increase auxiliary equipment such as igniter, control valve, also should be at the row of protection scope of the present invention.
