Description

Burner for liquid fuel

The utility model relates to the fluid combustion device technique field of using.

Along with continuous progress in science and technology and living standards of the people improve gradually, adopt the civilian burner of liquid fuel all generally to be promoted the use of at home and abroad, because liquid fuel not only has the major advantage of solid and gaseous fuel concurrently, and solved the major defect of solid and gaseous fuel, therefore use the fluid combustion device very popular.At present, more advanced burner with liquid fuel evaporation after just for the burning, mainly be divided three classes according to the vaporization mode: the first kind is a pressure-type, it is to rely on the liquid fuel steel cylinder of band pressure or inflate the pressure that is produced by artificial pressurization and realize liquid fuel evaporation, and when pressure was low, the air spouting velocity was low, mist of oil is of poor quality, vaporization not exclusively, it is insufficient to burn, and power consumption is high, and the steel cylinder of band pressure has many unfavorable factors such as dangerous, inconvenient, expense height.Second class is a volatile-type, and it is to utilize the natural physical characteristic of the extremely strong special liquid fuel of volatility and need not pressurize and inflate, but its unsafe factor is more, and requires the sealing property height of burner or storage fuel tank, and increases the fuel production cost.The 3rd class is the preheating vaporization type, it is to put small amount of liquid fuel earlier to ignite in preheater, liquid fuel heat in the gasifier is made its vaporization, the more preceding two class advanced persons of its performance, but the commercially available prod still has the following disadvantages at present: (1) ignition combustion plant automation degree is low, and most the need lighted a fire with hand then with tapping fluid fuel in the past preheater of hand, certain danger is arranged, can not resemble the natural gas igniting easily and use.(2) amount of tapping fluid fuel is difficult for grasping appropriate in the preheater, puts and has lacked the liquid fuel evaporation that can not make in the vaporizer, has put to overflow or be sprinkled upon the outside easily produce the fire alarm accident more.(3) required preheating time longer owing to be that vaporizer and liquid fuel integral body are heated, it is many to reach the required additional heat energy of vaporization, could normally use after the about 2 minutes kinds, extremely inconvenient.

The purpose of this utility model provides improved burning apparatus for combustion of liquid fuel and solves above-mentioned problems of the prior art, and it need not pressurize, and can use the more weak multiple liquid fuel of volatility, the automaticity height, and preheating time is short.

The purpose of this utility model is achieved through the following technical solutions.

Burning apparatus for combustion of liquid fuel described in the utility model, comprise shell body, control valve, ignition, preheater, air nozzle, current divider, vaporizer, feed tube, escape pipe, burner and main liquid reserve tank, it is characterized in that having certain metered valve upper end to be connected with escape pipe, middle-end is connected with main liquid reserve tank, and the lower end links to each other with preheater.

Burning apparatus for combustion of liquid fuel described in the utility model design preferably is that proportional valve, ignition switch are connected with link gear with control valve, the rotation of the operation knob by link gear, automatic sequence is finished to preheater and is put into quantitative liquid fuel, actions such as ignition and control flame size.

The better design of burning apparatus for combustion of liquid fuel described in the utility model is to be provided with an interlayer to form the rapidly pre-warming chamber in the vaporizer inner chamber, and the upper and lower part of rapidly pre-warming chamber is communicated with the air receiver and the bottom liquid-accumulating chamber on vaporizer inner chamber top respectively.

Burning apparatus for combustion of liquid fuel described in the utility model further design is that interlayer is by the thermostable heat insulation material or scribble heat insulating coat in the metal surface and make.Vaporizer is a tubular, and its top is bell mouth shape, in the bottom of vaporizer preheater is installed, at the horn mouth place of vaporizer install combustion device.On main liquid reserve tank, be provided with safety valve and liquid filling hole and port lid.

Adopt burning apparatus for combustion of liquid fuel described in the utility model to have the following advantages: (1) does not need compressed air or artificial pressurization to inflate, and does not carry the worry of steel cylinder.(2) general liquid fuel, particularly alcohols or its synthetic liquid fuel can burn well.(3) automaticity height can resemble the natural gas igniting easily and use.(4) be provided with the rapidly pre-warming chamber, shortened preheating time greatly, extremely easy to use.(5) place quantitative preheated liquid fuel automatically, liquid fuel can not overflow or spill and cause accident.(6) simple in structure, manufacturing cost is low, and is safe and reliable.(7) it is coal-fired user's a desirable regeneration product, and comparing it with natural gas does not need pipe laying, is convenient to move on to different local uses, and its investment only is the sixth of natural gas investment, and liquid fuel is easy to buy on market, does not have the sorrow of stopping the supple of gas or steam.

With reference to the accompanying drawings burning apparatus for combustion of liquid fuel described in the utility model is described in further detail.
