锅炉的NO_x排放量对污染环境影响很大,已引起世界各国的广泛重视。近年来,美国、日本等工业发达国家已对工业窑炉、动力装置NO_x的排放作了严格控制。本文就国外对研究NO_x的生成机理、控制原则、降低锅炉NO_x的具体措施及其效果和费用等作了较为全面的综述。编者并建议结合我国的经济能力与技术可行性及早对已运行的。特别是目前正在设计中的大容量燃煤电站锅炉排放NO_x的问题进行全面周密的研究,采取必要措施,以减少环境污染,保护人民身体健康。
Boilers NO_x emissions have a great impact on the polluting environment, which has aroused widespread attention of all countries in the world. In recent years, industrialized countries such as the United States and Japan have strictly controlled the emission of NO_x from industrial furnaces and power plants. In this paper, we make a comprehensive review about the formation mechanism, control principle, specific measures to reduce the NO_x of boilers and their effects and costs abroad. The editors and suggested combining the economic viability of our country with the technical feasibility of already running. In particular, the issue of NO_x emissions from large-capacity coal-fired power station boilers currently under design is being studied in a comprehensive and thorough manner and necessary measures are taken to reduce environmental pollution and protect people’s health.
