摘要
高压锅炉过热器在运行中受到飞灰、吹灰磨损,导致管壁减薄。通过采取改变管束固定方式、加装 防磨装置、去除吹灰枪管中的凝结水等措施,使低温过热器运行时间延长到16000h以上。
Abraded by flying ash and blowing ash, the tube wall of low temperature superheater of HP boiler was thinned during operation. Measures, such as changing fixing style of tube bundle, adding anti-abrasion equipment and removing the condensate from ashing blowing lance tube, were taken to prolong the operation time of low temperature superheater to over 16000h.
