桥头电厂五期锅炉送风机风压低原因分析及整改措施

Cause Analysis on Low pressure of the Air Feeder For the Boiler in Qiaotou Thermal Power Plant and the Precaution

桥电五期锅炉自投运以来，锅炉送风机存在出口风压较低的问题，炉内燃烧处在严重缺风工况，影响机组的安全经济运行。１９９７年１月、５月桥头电厂先后两次请西安热工研究所有关专业人员进行现场测试；根据测试数据，组织专业人员查原因、定措施、出方案、抓落实，使送风机风压低的问题终于得到初步解决，基本满足锅炉燃烧风量的需要。

Since the normal service of the generating units in Qiaotou secondary power plant,the output pressure of the air feeder had been remained at low pressure,and the lack of air had been influenced the safe and economical operation of the units.To solve the measurements are taken.The paper describes the details.
