Is it required that the torch fuel gas system have at least one alternative gas supply source?
Thread Content
The fuel gas supply for the torch is generally a branch of the natural gas pipeline network, with an additional supply of refinery fuel gas. May I ask if a single gas supply source is sufficient to meet the design requirements? Comments are welcome in the Process Management group
The design of the torch fuel gas system typically requires at least two fuel gas supply sources, primarily to ensure the continuity and safety of the system. If there is only one source of fuel gas, any issues with that source or the need for maintenance can affect the flare fuel gas system, thereby impacting the entire production process. Therefore, although only one fuel gas supply can meet the basic requirements of the flare fuel gas system, a backup fuel gas supply is usually provided to ensure its stability and safety. This is also a common practice in industrial design and management. I hope this answer is helpful to you. .
The specifications do not require a backup gas source. If it really stops working, a liquefied gas tank unit can be added on-site temporarily.
Could you please tell me the specific specifications?

There is no requirement for at least two gas supply lines
