What is the purpose of the shape designed around the torch tip?
Thread Content
As shown in the figure below, what are the three openings around the torch tip used for? What is that structure called, and why was it designed in that shape?
That is called a flame stabilizing ring; its purpose is to keep the flame stable at the torch outlet and prevent it from being blown away.
Also known as a flame concentrator; it allows a portion of the flame to burn more intensely, making it harder for the flame to go out
The flame-collecting element on the torch head is similar to the burner of a stove. Its function is to increase the uniformity and stability of the flame during combustion.

The stabilizing flame block (flame-concentrating block) is primarily used to stabilize the flame when a small amount of exhaust gas is emitted； It is difficult to prevent flashback when changing the outlet airflow direction during large amounts of exhaust gas emission. Wait!
I agree with the explanations from the people above. In normal production, the flame at the flare tip is not very large; there is no need for air defense measures nor any significant leakage of flammable gases. However, it is necessary to maintain a steady flame at the flare tip while minimizing unnecessary fuel loss, which requires keeping the flame small or low. The ring-shaped structure with small holes surrounding the flare tip serves this purpose. It allows the flame to burn steadily (after all, wind speeds are high at high altitudes; otherwise, it is easy for the flame to be blown out).
What was said upstairs is correct – a ring of flame-stabilizing elements (also known as flame stabilizers) is installed on the inner wall at the outlet of the torch tip. These elements are made of 310SS, and their purpose is to ensure stable combustion of the flame; they help maintain a stable flame ring whether the amount of gas released by the torch is small or large. Another function of the fire gathering block is to create a negative pressure area on the inner wall, in order to introduce more air and enhance complete combustion.
