火电机组灵活性改造及供热能力变工况特性计算研究

Study on the Flexibility Modification of Thermal Power Units and the Calculation of Variable Working Conditions of Heating Capacity

结合实际工程项目,分析了火电机组灵活性改造的必要性;围绕机组改造前的供热情况、三种备选改造技术、多种切缸改造方案比选对火电机组灵活性改造方案进行了整体梳理。在此基础上,对电力机组灵活性改造后供热能力变工况特性进行了计算,供参考。

Combining with actual projects, the necessity of thermal power unit flexibility modification is analyzed;the flexibility modification of thermal power units is based on the heat supply situation before the unit modification, three alternative modification techniques, and various cylinder cutting modification schemes are compared. The overall scheme has been sorted out. On this basis, the variable operating characteristics of the heating capacity of thermal power units after flexibility retrofit are calculated for reference.
