Abstract

The invention discloses efficient natural gas. The efficient natural gas consists of natural gas with purity higher than 95% in percentage by weight, and 0.3-0.5% of a liquid-phase synergistic additive in terms of weight percentage of the natural gas, wherein the liquid-phase synergistic additive consists of the following raw materials: 200# solvent oil, isopropanol, petroleum ether, ethylene glycol monoethyl ether, turpentine, tung oil, isooctyl nitrate, dimethyl carbonate, tert-butylferrocene or ferrocene, methyl tertiary butyl ether or n-octyl ferrocene, p-tert-butylcatechol, azodiisobutyronitrile and polyether. The efficient natural gas, through adding little liquid-phase synergistic additive in the natural gas, can obviously improve burning temperature and burning efficiency; meanwhile, the liquid-phase synergistic additive is low in corrosion and good in volatility on containers.

Description

technical field [0001] The invention relates to a high-efficiency natural gas; the gas can be used for metal cutting and welding. Background technique [0002] Among the industrial gas consumption in my country, 70% are propane gas and acetylene gas. When using acetylene gas to cut carbon steel, it is easy to cause the upper edge of the incision to melt, there is a lot of slag and it is not easy to clean, and the cut surface is partially hardened, which makes the cutting process unsatisfactory, and the use of acetylene will cause great pollution to the environment and is not environmentally friendly. . During welding, grinding is required, which increases the production cost. Shipyards in coastal areas have banned the use of acetylene on shipbuilding platforms in recent years and switched to other new cutting gases. People have been trying to use other fuels instead of acetylene as cutting gas for many years, but due to other fuels such as natural gas, liquefied petroleum ...
