本文详述近年来国内在平焰燃烧技术所取得的成就,介绍了另外一些新型节能燃烧器的原理、效能和国内的动向。论述了我国在煤气、重油和煤的燃烧技术的经验和存在的问题与改进意见。提出了充分利用放散的工业煤气,实行以煤代油,以气(高炉煤气等工业煤气)代油,以低级燃料代稀缺燃料和在小型轧钢厂直接燃煤的建议。 This article details the achievements made in the flat-flame combustion technology in China in recent years, and introduces the principle, efficiency and domestic trends of other new energy-saving burners. The experience, existing problems and improvement suggestions of China’s combustion technology of gas, heavy oil and coal are discussed. Proposed to make full use of the industrial gas emissions, the implementation of coal instead of oil, gas (blast furnace gas and other industrial gas) to replace low-grade fuels on behalf of the fuel and the proposed small coal-fired rolling mill directly.
