AI Technical Summary

Problems solved by technology

[0004] The combustion temperature of propane in the above technology is much lower than that of acetylene, and the combustion speed is slower, so the overall preheating time is longer, which brings inconvenience to the welding and cutting process

Abstract

The invention relates to the technical field of welding gun gas, in particular to environment-friendly combustion gas. The environment-friendly combustion gas comprises the following components in percentage by volume: 25-75% of propane and the balance of olefin. The mixed use of propane and olefin has the advantages of high combustion temperature and high combustion rate, and the fully combusted product is green and pollution-free.

Description

technical field [0001] This application relates to the technical field of welding torch gas, more specifically, it relates to an environment-friendly combustion gas. Background technique [0002] Gas is the general term for gaseous fuel, which can be burned to release heat for use by residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, and coal gas. Among them, the combustion gas for welding torches is taken as an example, which is mainly used for welding and cutting in maintenance points of small and medium-sized air conditioners and refrigerator maintenance industries. [0003] The combustion gas used in welding torches in related technologies is propane. Since propane was used in the field of welding and cutting in my country in the early 1990s, it has been considered as the best alternative gas for acetylene. Propane is a by-product of petroleum refining. At present, it is mainly used As ...
