The utility model is characterized in that the center of a fuel gas sleeve pipe is provided with a fuelgun, and thus a ring-shaped fuel gas passage is formed between the fuelgun and the sleeve pipe, and the tail end of the passage can be embedded with fuel gas spraying heads having different structures and shapes. Furthermore, a rotary air feeding and dispensing cylinder is arranged between a casing of the burner and the sleeve pipe inside the casing, air flows from a long hole of the cylinder body enters a straight flow air sleeve pipe to cause long flames, and air flows from a circular hole of the end surface of the cylinder enters a rotational flow air sleeve pipe to cause short and thick flames. The utility model has the advantages of compact structure, flexible regulation, convenient assembly and disassembly, wide applications and high durability.

Description

The long flame oil and gas combination burner

The utility model belongs to injection apparatus, relates to the heating of burning simultaneously of heavy residual oil and fuel gas and is used for the needed stable long flame oil and gas combination burners such as Industrial Stoves, smelting and heating, station boiler of expanded letter.

Liquid fuel is atomized and is tiny and uniform particulate; Fuel gas and combustion air give the abundant, quick of mixed or half premix.At present, can only realize general fuel oil and combustion gas, only be provided with and executed direct current wind and rotation wind simultaneously, in order to reach the control length of flame by this.

The purpose of this utility model is to large-scale stove or expanded letter heating furnace, provide adjustable, reliable, to adapt to the long flame oil and gas combination burner of different operating mode needs.

The purpose of this utility model is achieved in that a kind of novel oil gas burner, and it includes the oil gun of fuel filler and atomization gas inlet; Gas sleeve and shower nozzle.It is characterized in that combustion air through air feed distribution drum whereabouts two places: one is direct current wind, and one is rotation wind.Direct current airduct and Gas Pipe and flange welding connect firmly; Combustion air inlet short tube is welded on the eddy flow wind sleeve pipe, this sleeve pipe and inner flange welding.Inside and outside flange centering spiral marking connection, it is overall to form burner.

The utility model is compared with existing oil gas burner, be different oil kinds and different fuel gas highlightedly, also have convertibility with equal assembly at any time to adapt to this type according to need, dismounting is easy to be efficient low-consume energy product, fuel efficiency of the present utility model＞99.5%, combustion gas-100% is applicable to various expanded letter heating stoves and large-sized station boiler, also absorbs operation applicable to drying operation and chemical industry.

The utility model is described in further detail below in conjunction with drawings and Examples: consult shown in Figure 1, the placement of this burner, best in a horizontal manner, operating mode has the different time also can be vertical certainly, tilts to place.The center of device is worn and is being put oil combustion gun 3, combustion gas 12 is passed gas sleeve 1 through inlet, by shower nozzle 2 ejections, the length of flame during for smooth combustion is provided with combustion-supporting direct current wind sleeve pipe 5, and combustion air is the direct current wind with certain speed through this. can play the effect of the delivery length of flame.Again for burn fully, good, ad hoc have an eddy flow wind sleeve pipe 6.Its air quantity is dispensed into combustion air 10 the direct current wind and the eddy flow wind of going into ring flat-plate 8 of sleeve pipe 5 as required by air feed distribution drum 9 with ratio.The other end of oil gun has the Pressure gauge 14,13 on fuel filler 15, atomization gas inlet 16 and the pipe thereof; Atomizing gas port and passage are 45 ° of angles of cut on the oil gun, thereby atomization gas reduces drag losses, and rotate gradually in traveling process, and this will help atomizing.This utility model burner system is made up of centrosymmetric four layers of sleeve pipe.Oil gun 3 constitutes central core, and an end inserts in the centre bore of gas spray head 2, and end is solid by 17 in stuffing-box in addition; It is outer for the second layer is that gas sleeve 1 and the 3rd layer are direct current wind sleeve pipe 5, and they all are weldingly connected with outward flange 18.Being welded with combustion air inlet short tube 10 vertical the inserting of choosing hook 11 is welded on the 4th layer of sleeve pipe (being outer layer sleeve), it welds the 4th layer of sleeve pipe mutually with inner flange 19 again, and next 18,19 groups promptly are combined into this utility model-long flame oil and gas combination burner to flange with bolted.

Consult Fig. 2, Fig. 6, Fig. 7, shown in Figure 8, if combustion air total amount Q enters the 81-5 of ring flat-plate 8 through the 9a1-5 of air feed distribution drum 9, this moment, all combustion air Q went in the sleeve pipe 6 of eddy flow wind, if move 9C, revolve 36 ° of circulation wind that then enter in the sleeve pipe 6 and will be 4/5Q, then entering eddy flow wind when revolving 72 ° is 3/5Q, if be threaded to 180 ° of this moments then the eddy flow air quantity be 0; With respect to the direct current air quantity is Q, gang up corresponding with 51-5 of 9b1-b5 of this moment.

Consult Fig. 3, Fig. 4, shown in Figure 5, this be three kinds of gas spray head because of different effects, select different combustion gas for use, its effect is different, wherein Fig. 3 orifice center line parallel claims the single flow shower nozzle in axis, it brings up and is straight flame; Fig. 4 spray orifice is emanant, and promptly burned flame has angle; Fig. 5 spray orifice system is the anglec of rotation with axis, claims to revolve the formula of penetrating, and under the preceding topic that guarantees combustion efficiency, its direction of rotation should be identical with the direction of rotation that spinning disk 7 is caused, and flame at this moment can protract, otherwise then flame is short and thick.

Fig. 8 is one of two big parts in this utility model long flame oil, the gas combined combustion device, and promptly coal gas sleeve pipe 1, combustion-supporting direct current wind sleeve pipe 5 are welded on the outward flange 18 together; Oil gun 3 is welded in the stuffing-box 17 on the coal gas sleeve pipe 1 and fastens.But if the oil gun of changing different size disassemble packing box flange then.Centering compresses packing box flange after inserting most favorable position again.

The mechanism of this utility model comprises part:

Dominant mechanism of the present utility model, comprise two parts, (1) fuel oil: be intended to the good of its atomizing effect, be Suo Taier mean value: SDM＜30 μ m, make the formation microvesicle of fuel oil-100% according to atomization gas, satisfy to the step-down bubble by former pressured state and become big, be out of shape, shear, tear last explosion and be extremely even and fine mist.Its efficiency of combustion＞99.5%.

(2) combustion gas: according to combustible gas state (temperature, pressure, molecular structure and composition) designing optimal flow velocity stimulate the menstrual flow and with the relevant position of combustion air, make and reach the required heated condition of technology, it is flame profile ... make it to accomplish premix or half premix, so its efficiency of combustion can reach 100%.
