Description

A low power burner

Technical Field

The utility model relates to the technical field of burners, in particular to a low-power burner.

Background Art

The burner is a machine in which diesel passes through the oil inlet pipe and drips into the atomizing net. The atomizing net atomizes the diesel. When the ignition rod is energized, high temperature is generated. The atomized diesel encounters the high temperature and is ignited.

A Chinese patent (Announcement No.: CN105546531B, Announcement Date: May 24, 2019) discloses a burner, including a combustion tube, the inner cavity of which is provided with at least two fuel nozzles, and the fuel nozzles are all located at the air inlet end of the combustion tube, so that the fuel and air can be mixed evenly. Each fuel nozzle is supplied with oil by its own fuel pump, and the fuel pump pumps the fuel into the fuel nozzle through a fuel pipe for outward spraying. The installation angle of the fuel nozzle is pre-set, and the fuel sprayed from each fuel nozzle can intersect with each other. It is easier to start the burner when it is ignited. As long as one of the fuel nozzles is ignited, it can work together with other fuel nozzles, thereby improving the success rate of ignition. The fuel sprayed from the fuel nozzles can intersect with each other. During normal operation, the fuel nozzles spray flames to form a high-temperature zone. The fuel that fails to achieve complete combustion in one fuel nozzle will be sprayed onto the flame of another fuel nozzle and ignited by the other fuel nozzle, thereby achieving complete combustion.

The above patent solves the technical problems of low ignition success rate and incomplete fuel combustion, but it is necessary to set the installation angle of the burner fuel nozzle in advance, which increases the operation steps. In addition, the fuel sprayed from the fuel nozzle can intersect with each other. During normal operation, the fuel nozzle sprays flames to form a high-temperature zone. The fuel that fails to achieve complete combustion in one fuel nozzle will be sprayed onto the flame of another fuel nozzle and ignited by the other fuel nozzle, thereby achieving complete combustion. Moreover, multiple clusters of flames converge together to reach a higher temperature. This design requires a larger combustion chamber space, and is not universal for vertical or horizontal types, and has a limited range of applications.

Utility Model Content

The technical problem to be solved by the utility model is to provide a low-power burner in view of the defects of the background technology. Compared with the prior art, the technical solution can save labor costs, save time and effort, greatly improve the working efficiency, and has a wide range of adaptability.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A low-power burner comprises an inner wall of a combustion chamber, a combustion chamber bottom plate welded to the bottom of the inner wall of the combustion chamber, ignition rod mounting studs welded to both sides of the inner wall of the combustion chamber, a middle fire partition plate welded to the top of the inner wall of the combustion chamber, the inner wall of the combustion chamber welded to the outer wall of the combustion chamber, an oil inlet pipe is arranged on the top of the ignition rod mounting stud, an atomizing net and an ignition rod are arranged inside the ignition rod mounting stud, and the atomizing net is located below the oil inlet pipe.

Preferably, the middle fire-isolating plate is welded to the outer wall of the upper combustion chamber, and the top fire-isolating plate is welded to the top of the outer wall of the upper combustion chamber.

Preferably, a heat radiation net is installed inside the outer wall of the upper combustion chamber.

Preferably, a heat radiation net is installed on the inner side of the inner wall of the combustion chamber, and the outer side is wrapped with insulating glass fiber wool; the outer wall of the combustion chamber is welded to the outer side of the insulating glass fiber wool, and the bottom and top of the outer wall of the combustion chamber are fixedly connected to the combustion chamber bottom plate and the middle fire isolation plate respectively.

Preferably, the combustion chamber bottom plate is fixedly connected to an air distribution ring on one side of the combustion chamber, an air distribution plate is installed on the top of the air distribution ring, an air guide plate is provided on the outer side of the combustion chamber bottom plate, and a sealing plate is installed at the bottom of the air guide plate.

More preferably, the combustion chamber bottom plate is welded to the air distribution ring, the air distribution ring is welded to the air distribution plate, the outer side of the combustion chamber bottom plate is welded to the air guide plate, and the bottom of the air guide plate is welded to the sealing plate.

Compared with the prior art, the utility model adopts the above technical solution and has the following technical effects:

1. The combustion chamber space is small, so the overall volume of the burner is small, and it can be used vertically or horizontally. At the same time, the diesel drips into the atomizing net through the oil inlet pipe. The diesel passes through the atomizing net to form atomized diesel. When the ignition rod is energized, high temperature is generated. The atomized diesel encounters high temperature and is ignited to form a flame, which improves the ignition success rate.

2. The flame in the combustion chamber generates a certain amount of air through the external fan. The wind follows the direction of the air guide plate, passes through the bottom plate of the combustion chamber, and then enters the combustion chamber through the air distribution ring and the air distribution plate, bringing the flame into the outer combustion chamber and blowing out the burner. It can be used for portable cooking stoves, fuel air heaters, fuel water heaters and other equipment, with a wide range of applications.

3. There is no need to set the installation angle of the burner fuel nozzle in advance, which saves labor costs, saves time and effort, and greatly improves work efficiency.
