Benefits of technology

This new technology helps create better cuts by concentrating naturally occurring gases like methane into smaller particles that are easier for heated metal or plasma arc tools to ignite without burning them out too much. It also improves safety during operation due to its ability to mix air together beforehand instead of just adding an oxidizing agent (acetylenes). Additionally, this process saves on energy usage because there're no harmful chemicals used while working at very low temperatures.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving production processes for reducing carbon dioxide (CO2) emission from fossil fuel-fired power plants while also addressing issues with excessive use of electrical current or expensive materials used during manufacturing processes.

specific Embodiment approach 1

[0007] Specific embodiment one: this embodiment is that a kind of high-energy welding and cutting gas is mixed by nano-combustion accelerator and natural gas, wherein the volume ratio of the quality of nano-combustion accelerator and natural gas is (1kg~2kg): 100m 3 .

[0008] The invention uses a nano-combustion accelerator to concentrate the natural gas flame, raise the flame temperature, achieve the use effect of acetylene gas, improve the cutting quality of the workpiece, ensure safety without tempering, and greatly reduce the consumption of gas and oxygen. A bottle of 3 cubic meters of high-energy welding and cutting Gas can replace a bottle of 3 kg acetylene gas, the cost is only 1 / 5 of acetylene gas, and the high-energy welding and cutting gas only needs to be natural gas, which reduces environmental pollution compared with acetylene gas.

specific Embodiment approach 2

[0009] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the nano-combustion accelerator consists of 20 to 30 parts of aviation kerosene, 10 to 15 parts of ethanol, 10 to 25 parts of n-butanol, 12-15 parts of ethyl acetate, 10-15 parts of ethylene glycol monobutyl ether, 5-10 parts of tert-butyl hydroperoxide, 1.8-2.2 parts of 2-pentanone, 0.4-0.6 parts of nano-alumina, 0.4-0.6 It is prepared by mixing one part of nano iron oxide and 1.8 to 2.2 parts of borane-pyridine complex. Others are the same as in the first embodiment.

[0010] The combustion process is a typical non-isothermal reaction, and the reactants at room temperature change into products immediately after entering the flame. Since the process is completed instantaneously, it can be approximately considered that the reaction is completed under adiabatic conditions, and all the heat released by the reaction is used to heat the product and the inert gas doped in the rea...

specific Embodiment approach 3

[0011] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the nano-combustion accelerator is composed of 28 parts of aviation kerosene, 15 parts of ethanol, 12 parts of n-butanol, 15 parts of Ethyl acetate, 15 parts ethylene glycol monobutyl ether, 10 parts tert-butyl hydroperoxide, 2 parts 2-pentanone, 0.5 parts nano-alumina, 0.5 parts nano-iron oxide, and 2 parts borane-pyridine complex mixed. Others are the same as in the first or second embodiment.

Abstract

The invention relates to high-energy welding-cutting gas, which relates to welding-cutting gas, and aims to solve the problems of environment pollution, high energy consumption and high cost existing when acetylene gas is used as welding-cutting gas. The high-energy welding-cutting gas is formed by mixing nano flame accelerator with natural gas, wherein the nano flame accelerator is formed by mixing jet fuel, ethanol, n-butyl alcohol, ethyl acetate, ethylene glycol monobutyl ether, tert-butyl hydroperoxide, 2-pentanone, nanometer aluminium oxide, nanocrystalline iron oxide and borane-pyridinecomplex. The high-energy welding-cutting gas has the advantages that: the nano flame accelerator is adopted, so that the flame of the natural gas is concentrated, the flame temperature rises, the useefficacy of acetylene gas is achieved, the cutting quality of workpieces is improved, safety is realized without tempering, the gas consumption and the oxygen consumption are greatly reduced, a bottle of high-energy welding-cutting gas with the volume being 3 cubic meters can replace a bottle of acetylene gas with the weight being 3 kg for use, the cost of the welding-cutting gas is one fifth of the cost of the acetylene gas, and the main component of the high-energy welding-cutting gas is the natural gas, so that the environment pollution is reduced compared with the acetylene gas. The invention is mainly used for preparing the welding-cutting gas.
