Abstract
The utility model relates to the improvement to the existing kerosene vaporizing stove, mainly composed of a combustion stove end, a vaporizing tube arranged in the combustion field of the combustion stove end, and an injection bent tube and a kerosene storage tank connected between the vaporizing tube and the combustion stove end. The outlet end of the vaporizing tube is connected with the injection bent pipe through an injection nozzle. When the utility model is in use, air is sucked in from the injection nozzle and the injection bent pipe twice, and the excess air coefficient alpha < 1 K > has relatively small value during small flame to maintain normal combustion, so the combustion stove end with a large aperture gas outlet can be adopted to reduce working pressure in the vaporizing stove.
Description
The utility model relates to a kind of burner.Being particularly related to a kind of is the kerosene gasification burner of fuel with kerosene.
Existing kerosene gasification burner generally constitutes by oil storage tank, burning jamb, generating tube, injection bend pipe, and wherein generating tube is arranged in the combustion field of burning jamb, and its arrival end and oil storage tank join, and the port of export joins by an injection bend pipe and burning jamb.Earlier generating tube is heated with a preheating device during work, kerosene is flowed through spray into the injection bend pipe after this has had generating tube vaporization of uniform temperature, suck certain air and in the injection bend pipe, be mixed and form the fuel gas mixture possess the good combustion performance, send into burning jamb and from the combustion gas discharge port of burner, spray burning.The kerosene gasification burner of this disposable introducing air capacity is for guaranteeing the abundant burning of combustion gas, its excess air coefficient a
LkGeneral all designs bigger all adopted the burner of the combustion gas discharge port of small-bore simultaneously, utilizes the extinguishing in hole, small-bore to be used for avoiding taking place tempering phenomenon.This anti-backfire way makes that the pressure of whole combustion system is higher, causes the working pressure of requirement general all between 0.1～0.2Mpa.Thereby need often to give the oil storage tank aerating, promptly trouble is required great effort again; Simultaneously, its oil storage tank need adopt thicker steel plate to make and be provided with annexes such as Pressure gauge, complex structure, and the cost of manufacture height, security is not enough.
The purpose of this utility model is intended to reduce the working pressure of kerosene gasification burner, provides a kind of and also can keep its normal combustion and the minute-pressure formula kerosene gasification burner of tempering phenomenon can not take place under the minute-pressure state.
The minute-pressure formula kerosene gasification burner of realizing the purpose of this utility model comprises burning jamb, be arranged on the generating tube in the combustion field of burning jamb, the oil storage tank that is connected in the injection bend pipe between the generating tube port of export and the burning jamb and is connected in the generating tube arrival end, the port of export of described generating tube is connected with the injection bend pipe by an injection type nozzle, this injection type nozzle is one to have the tubular nozzle of a small-bore arrival end and a large aperture port of export, has the air that is communicated in nozzle chamber and introduce the hole on the tube wall of tubular nozzle.Gaseous state kerosene during work after the generating tube vaporization is from the past large aperture of arrival end spray, the small-bore port of export of driving nozzle, swiftly flowing gaseous state kerosene forms certain vacuum in nozzle chamber, air suction inlet from tube wall sucks that air in certain amount is sneaked into the gaseous state kerosene and sprays into the injection bend pipe from the port of export of nozzle, introduce once again the part air in the injection bend pipe mixing input burning jamb for the burning use.When gaseous state kerosene (big flame) more for a long time, also more from the nozzle amount of air drawn, also higher from the speed that its port of export sprays into the injection bend pipe, the air capacity that is drawn into once again in the injection bend pipe is also bigger, reaches bigger a
LkValue is to guarantee the completing combustion of coal gas.Be higher than flame transmission speed because gas flow rate is big this moment, therefore tempering phenomenon can not take place.When gaseous state kerosene (flammule) more after a little while, less from the nozzle amount of air drawn, its speed that sprays into the injection bend pipe is very low, and the air capacity that is inhaled into once again in the injection bend pipe is less, a at this moment
LkBe worth lessly, also tempering phenomenon can not take place.Because the flame of this moment is less, extraneous air is easy to diffuse in the middle of the flame, makes coal gas reach burning completely.
The utility model comes to join with the injection bend pipe by set up a driving nozzle at the generating tube port of export, makes excess air coefficient a
LkWhen flammule, have less value and tempering phenomenon does not take place to keep its normal combustion, thereby can adopt burning jamb with wide-aperture combustion gas discharge port, to reduce the operating pressure requirement of gasification burner, according to test result, only need the tank pressure of 0.005Mpa normally to use, working pressure is less than 1/10th of existing commercially available gasification burner.Such pressure to volume be 12 liters, the oil storage tank of the 5Kg kerosene of packing into, only need adopt rubber ball to make air-inflating tools, push more than ten time and just can reach, convenient, laborsaving, save time.Also can not inflate and oil storage tank is seated in the place that is higher than more than the burner 60cm, the static pressure of its generation also can be kept its not tempering of normal combustion.Because it is low that pressure requires, and can adopt general sheet iron or plastics to manufacture its oil storage tank fully, also need not to set annexes such as Pressure gauge, thereby can make designs simplification, production cost also reduces greatly, simultaneously, uses also safer.
Provide embodiment below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the partial top view of Fig. 1
Fig. 3 is Figure 1A-A enlarged drawing
As described in Fig. 1,2, oil storage tank 1 of the present utility model, generating tube 2, burner 3, injection bend pipe 4 are the version that adopts existing gasification burner.Wherein, connect by a driving nozzle 5 between generating tube 2 and the injection bend pipe 4, driving nozzle 5 has the arrival end 6 and a large aperture port of export 7 of a small-bore, referring to Fig. 3, its small-bore arrival end 6 joins with generating tube 2, and the large aperture port of export 7 joins with the injection bend pipe.On the nozzle tube wall, have the air that communicates with nozzle chamber and introduce hole 8.Oil storage tank 1 can adopt general sheet iron oil tank, and air-inflating tools can select for use rubber ball with low cost 9 directly to be provided on the oil tank.
Claims (1)
1, a kind of minute-pressure formula kerosene gasification burner, comprise burning jamb, be arranged on the generating tube in the combustion field of burning jamb, the oil storage tank that is connected in the injection bend pipe between the generating tube port of export and the burning jamb and is connected in the generating tube arrival end, it is characterized in that also being provided with an injection type nozzle between the port of export of described generating tube and the injection bend pipe arrival end, this injection type nozzle is one to have the tubular nozzle of a small-bore arrival end and the footpath at a gulp port of export, on the tube wall of tubular nozzle, have the air that is communicated in nozzle chamber and introduce the hole, the small-bore arrival end and the generating tube port of export of nozzle join, and the arrival end of the large aperture port of export and injection bend pipe joins.
