随着我国动力工业的飞速发展,大型和中间再热锅炉的出现,管式预热器已经越来越不能适应锅炉发展的需要了,因此必须采用另一种传热型式,回转式空气预热器就是大型锅炉的发展方向。我厂“125”机组所采用的回转式空气预热器具有风罩转动的特点,这是我国空气预热器制造史中的第一次尝试。经过三年多来的运行“实践、认识、再实践、再认识”,终
With the rapid development of China’s power industry, the emergence of large and intermediate reheat boilers, tubular preheaters have become increasingly unable to meet the needs of the development of boilers, it is necessary to use another heat transfer type, rotary air preheating The boiler is the direction of the development of large boilers. The rotary air preheater adopted by our factory “125” unit has the feature of wind cover rotation, which is the first attempt in the history of manufacturing air preheater in our country. After more than three years of operation, “practice, understanding, practice, re-understanding” and finally
