China's metallurgy, machinery, building materials and other industries have about 10,000 flame furnaces for industrial heating and heat treatment, which consume a large amount of fossil fuels each year, accounting for about 8% of the total energy consumption of China's industrial enterprises. Although China is a large energy producing country, it is also a large energy consuming country. The effective use of energy has become an important link restricting China's economic development. Among them, especially fossil energy is a non-renewable energy. A large amount of carbon dioxide and harmful gases emitted after combustion have seriously polluted the atmosphere and damaged our living environment. Therefore, saving energy and protecting the environment are great achievements for the benefit of mankind and future generations
