美国燃煤工业锅炉技术

介绍了美国工业锅炉的基本情况和主要的燃煤工业锅炉技术,分析了锅炉专用煤的要求及燃煤工业锅炉的污染控制技术。分析发现,美国的燃煤工业锅炉运行年代长,通过不断技术改造使锅炉保持较高的运行效率;美国对不同类型锅炉的煤质有专门规定,以保证锅炉高效率燃烧和低污染排放。美国燃煤锅炉采用各种污染物减排措施,保证了污染物达标排放。 This paper introduces the situation of industrial boilers and major coal fired industrial boilers technologies, describes the coal specifications and pollution control technologies for industrial boilers. It is found that the industrial boilers have kept higher operation efficiency through continuous technical transformation due to older age of the boilers. Special coal quality stipulations are for coal fired boilers in the US in order to ensure higher combustion efficiency and lower emissions. Coal-fired industrial boilers use various emission reduction measures, resulting in emission meeting the standards
