Abstract

The utility model relates to a gas fuel burner, which consists of a nozzle, an air mixing pipe, a buffering chamber and a furnace end cover. The utility model is characterized in that the fuel and the air are designed by using the secondary mixing, one end of the air mixing pipe is connected with the buffering chamber, and the other end of the buffering chamber is provided with an air vent and an one-time air mixing pipe. The one-time air mixing pipe is provided with a one-time air vent, one end of the one-time air mixing pipe is inserted into the air mixing pipe, and the other end is communicated with the nozzle. The diameter of the cylindraceous buffering chamber is 2 to 8 times of the diameter of the air mixing pipe. The furnace end cover is provided with a plurality of direct injection shower rose type fumaroles. when in use, the furnace end cover is covered onto the buffering chamber, the sufficiently mixed combustion gas is sprayed out and burn from the fumaroles on the furnace end cover. The utility model has the advantages of simple structure and reasonable structure, employed secondary mixing protocol of both fuel and gas, so as to make the mixed gas fuel equal, sufficient combustion and high thermal efficiency.

Description

Gaseous fuel burners

The utility model relates to the burner of making fuel with gas.

It is a lot of at present to make the burner kind of fuel with gas, but also has the imperfection part, and its efficiency of combustion has much room for improvement.

To be that design is a kind of make the burner of fuel with gas to the purpose of this utility model, and this burner structure is simple, and fuel combustion is abundant, thermal efficiency height.

The utility model is made up of nozzle, gas mixing pipe, surge chamber, stove top.It is characterized in that:

Fuel and air adopt the secondary Mixed Design, its structure is: an end of gas mixing pipe is connected with surge chamber, the other end of gas mixing pipe is provided with pore and a gas mixing pipe, have primary blowhole on the gas mixing pipe, one end of a gas mixing pipe stretches into gas mixing pipe inner air vent place, and the other end connects with nozzle outside gas mixing pipe.

Surge chamber is the round barrel shape structure, and its diameter is 2～8 times of gas mixing pipe, and surge chamber has a through hole that is connected with gas mixing pipe.

Stove top is provided with some fumaroles, during use stove top is placed on the surge chamber, allows the sufficient burning gases of the interior mixing of surge chamber burn from the fumarole ejection on the stove top.

The utility model is simple and reasonable for structure, adopts fuel and gas secondary hybrid plan, makes that mixed gaseous fuel is even, sufficient combustion, thermal efficiency height.

Example with accompanying drawing is further described the utility model below:

Fig. 1 is a shape assumption diagram of the present utility model;

Fig. 2 is the cutaway view of Fig. 1;

Fig. 3 is a horizontal air intake form outline drawing of the present utility model.

Among the figure, 1-stove top, 2-surge chamber, 3-fixed screw, 4-tube connector, 5-gas mixing pipe, 6-gas mixing pipe, 7-pore, 8-primary blowhole, 9-nozzle, 11-stay the kindling material device, 12-burning fumarole, 13-diffusion tip.

As Fig. 1, Fig. 2, shown in Figure 3, the utility model is made up of nozzle 9, gas mixing pipe 5, surge chamber 2, stove top 1 etc.One end of gas mixing pipe 5 is connected with surge chamber 2 by tube connector 4, and it is fixing with tightening up screw 3, the other end of gas mixing pipe 5 is provided with pore 7 and a gas mixing pipe 6, have primary blowhole 8 on the gas mixing pipe 6, one end of a gas mixing pipe 6 stretches into gas mixing pipe 5 inner air vents 7 places, the other end of a gas mixing pipe 6 connects with nozzle 9, with the puff prot of nozzle 9 be adjusted in primary blowholes 8 in gas mixing pipe 6 near.

Surge chamber 2 is the round barrel shape structure, and its diameter approximately is 3 times of gas mixing pipe 5, and as adopting end intake method, then surge chamber 2 bottom center have a through hole that is connected with gas mixing pipe 5.As (as Fig. 3) has a through hole that is connected with gas mixing pipe 5 at the side of surge chamber 2 when adopting horizontal intake method.

Stove top 1 is provided with the burning fumarole 12 of some gondola water faucet types, there is a boss in the central authorities of stove top 1, boss central authorities establish through hole, boss loam cake one diffusion tip 13, during use stove top 1 is placed on the suitable for reading of surge chamber 2, allow surge chamber 2 interior burning gases burn from burning fumarole 12 ejections on the stove top 1, the effect of diffusion tip 13 is to prevent that firepower is too concentrated as establish use optionally.

During use, nozzle 9 is connected to air supply source, makes fuel gas when nozzle 9 sprays into a gas mixing pipe 6 when opening air valve, air also enters and combustion gas mixing from primary blowhole 8 simultaneously, after gas mixing pipe 6 ejections, at this moment air enters with combustion gas from pore 7 again and mixes once more.The combustion gas that is mixed with air further enters surge chamber 2 after the mixing through one section long gas mixing pipe 5, and last combustion gas is from the 12 ejection burnings of burning fumarole.

Stay kindling material device 11 for convenient igniting is provided with, will stay kindling material device 11 also to be connected to air supply source during use.
