AI Technical Summary
The existing closed floor torch center burner does not provide enough oxygen, resulting in insufficient combustion, black smoke, and even inability to ignite. After a long period of combustion, the temperature inside the torch is higher than the surrounding temperature, resulting in weakening of convection and reducing air supply.
A closed floor torch center natural air supply device is designed, including a columnar frame and a combustion tower. By opening multiple square ports at the lower part of the columnar frame and installing a mesh cover plate, a new air inlet passage is formed to increase air supply.
By increasing air supply, the burner is ensured to provide sufficient oxygen supply and sufficient combustion, avoid black smoke and inability to ignite, improve convection in the torch, and improve the air supply effect.

Abstract
Description
Technical Field

[0002] The ground flare is a safety device for treating waste gas from industries such as petrochemicals, coal chemicals, and ethylene. However, the existing closed ground flare burners are densely arranged with few gaps. After the burners are ignited, air is mainly supplied by convection in the up and down directions. When the multi-stage burners are ignited at the same time, the outer burners are fully supplied with oxygen, the gas on them is also fully burned, and the flame is normal; the central burner is insufficiently supplied with oxygen, the combustion is incomplete, and black smoke is emitted. When the lack of oxygen is serious, the central burner will not be able to ignite. Or it will seek oxygen upward to form a flame-off combustion. And when the multi-stage burners burn at the same time for a long time, the temperature inside the entire closed flare will be higher than the temperature around the flare. In this way, the rising hot air flow will increase in the flare, the descending cold air flow will decrease, the convection in the overall flare will be weakened, and the air supply will be reduced as a whole. The gas in all burners seeks oxygen upward to form a flame-off combustion, and the flame emerges from the barrel. Therefore, how to provide a closed ground flare center natural air supply equipment that can increase the air supply to ensure normal combustion is a problem that technicians in this field need to solve urgently.
