As a clean energy, natural gas can reduce sulfur dioxide and dust emissions by nearly 100%, reduce carbon dioxide emissions by 60%, and reduce nitrogen oxide emissions by 50%. It also helps to reduce acid rain formation and alleviate the greenhouse effect of the earth, and fundamentally improves environmental quality. However, natural gas is a non-renewable energy source, so in order to save energy, make its combustion sufficient, and at the same time reduce the emission of nitrogen oxides, it is one of the problems that need to be solved at present.

[0003] Now additives can be added to natural gas for combustion support and to improve the calorific value of the gas. However, existing additives cannot be directly added (participate) to natural gas because of their large particle size. Therefore, an atomizing device needs to be used.
