Liquefied natural gas combustion aid

Abstract

The invention discloses a combustion improver for liquefied natural gas. The combustion improver comprises, by weight, 20-35 parts of tung oil, 10-25 parts of ethanol, 10-30 parts of n-butanol, 10-27 parts of cyclopentanol, 12-32 parts of ethylene glycol monobutyl ether, 5-20 parts of methyl ethyl ketone and 2-12 parts of borane tetrahydrofuran. The combustion improver has the advantages that the calorific value of the fuel gas can be increased effectively, the combustion speed of the liquefied natural gas can be increased greatly, high temperature can be obtained by combustion in oxygen, the liquefied natural gas with the combustion improver can effectively replace acetylene and be used for flame welding and cutting of metal, the firing point of fuel can be lowered, fuel can be saved, and deep application of the fuel can be achieved.

Description

technical field [0001] The invention relates to the technical field of energy and chemical industry, in particular to a combustion aid for liquefied natural gas. Background technique [0002] Today's world is facing a large number of global problems, one is the oil energy crisis, but environmental pollution. The world's proven oil reserves are 142.1 billion tons, with an average annual production of 3.56 billion tons in nearly 10 years, and it can last for up to 40 years. my country's oil reserves are limited, oil is mainly imported, and the dependence on foreign energy is as high as 55%, which has entered the energy early warning system. [0003] The burning speed of natural gas in oxygen is slow, and the thermal decomposition needs to consume a lot of energy. The decomposed natural gas has more water molecules, which consumes more heat during the combustion process, resulting in a significant reduction in the calorific value of natural gas combustion. Propane gas and ace...

Problems solved by technology

Therefore, the efficiency of using LNG in winter is more than 20% lower than that in summer, and the gas consumption is increased by more than 30%.

[0004] At present, the combustion speed of acetylene is faster than other fuels, and it used to be the most important industrial gas. This year, in line with the needs of energy conservation and environmental protection, propane, propylene, liquefied petroleum gas or natural gas have gradually replaced acetylene as industrial fuels, but natural gas exists. The above-mentioned unfavorable characteristics such as low combustion temperature and low combustion speed need to be further improved
