Combustion synergist for industrial fuel gas

Abstract

The invention relates to a combustion synergist for natural gas and liquefied petroleum gas used for cutting and welding of metals. The combustion synergist comprises a solvent, a solubilizing agent, a combustion catalyst, a combustion improver and a dispersant. The combustion synergist provided in the invention can substantially improve combustion temperature, heat and speed of industrial fuel gas, enables a high flame temperature, a short preheating time, a fast cutting speed, a smooth cutting surface of metals and no adherent dross to be obtained during cutting of metals, can be fully mixed with industrial fuel gas, promotes complete combustion of industrial fuel gas, does not produce black smoke, residues or pollutants and has the advantages of safety, convenience, environmental friendliness, convenient popularization and application, etc. The combustion synergist can be widely used for a variety of industrial fuel gas and is especially applicable to natural gas and liquefied petroleum gas.

Description

technical field [0001] The invention belongs to the technical field of industrial gas combustion synergists, in particular to natural gas and liquefied petroleum gas combustion synergists for metal cutting and welding. technical background [0002] Industrial gas combustion synergist is a class of fine chemicals that can increase the combustion temperature of industrial gas, accelerate its combustion speed, and improve its calorific value and other properties. It is usually used in metal cutting and welding after mixing with industrial gas. Acetylene gas used to be the most important industrial gas. In recent years, due to the needs of energy saving and environmental protection, the industry has gradually begun to replace acetylene with propane, propylene, liquefied petroleum gas or natural gas as industrial gas. However, when the above-mentioned industrial gas is used in industrial cutting or welding, there are disadvantages such as low combustion temperature, slow combus...

AI Technical Summary

Problems solved by technology

[0006] The main disadvantages of this patent are: 1) The combustion temperature of the industrial gas after adding the liquid phase synergist is still lower than the combustion temperature of acetylene gas, and the preheating time for metal is longer, so its use effect is not as good as that of acetylene gas

2) The liquid phase synergist has too many components and complex components, some of the raw materials are not easy to obtain, and some of the raw materials are expensive

In industrial applications, the cutting gas is usually transported to workshops or workplaces through pipelines, so some tert-butylferrocene and n-octylferrocene residues will be deposited in the pipelines, which not only causes waste of raw materials , which also causes the flame temperature of the gas to not reach the predetermined level

In addition, as the amount of residue deposition in the pipeline increases, it will hinder the transportation of gas, which is not conducive to industrial production

4) The liquid-phase synergist can only be applied to propane gas, and the scope of use is too narrow to ensure that when the supply of propane gas is insufficient, other gases are used to replace it, which is not convenient for industrial production
