直接空冷机组空冷凝汽器运行风险分析

火电发电机组采用空冷凝汽器来代替湿冷凝汽器是设计思想的变革,这种设计方案实施后,对机组节约水资源会产生很好的效果,但会相应带来运行风险。通过危险源辨识、风险分析,找出相对高风险因素,预测风险产生的后果,进行风险评估,提出切实可行的措施,为设计思想变革、实施扫清道路;同时对相对高风险因素等问题进行针对性分析,提出有效的技术措施,以提高机组的安全性和经济性,供发电公司参考。

Analysis on Operation Risk of Air-cooled Condenser in Direct Air-cooled Unit

In the thermal generation unit design,using the air-cooled condenser to replace the water-cooled condenser is a revolution in design philosophy.The realization of this design scheme can bring a good effect in saving the water resource;but it could bring relevant operation risk.According to the hazard identifi cation and risk analysis,the relative higher risk factors were found out;the aftermath of the risk factors was forecasted;the risk assessment was accomplished;and the practical and feasible measures we...
