结合铁岭发电厂２号机组协调控制系统的改造，针对锅炉回转式空气预热器ＬＦＫ－３型漏风自动控制系统设计不合理、故障率高、漏风量大等影响和制约锅炉燃烧系统及协调控制系统自动投入的问题，从产生故障的具体原因入手，进行整体论证分析，得出相应对策并制定具体实施方案，对系统进行了全面改造。改造后系统投入控制效果好，对同类型机组的漏风控制系统改造具有参考和借鉴意义。
Combining with the reconstruction of Coordination Control System of Unit 2 in Tieling Power Plant, in view of the unreasonable design of LFK-3 type air leakage automatic control system for boiler rotary air preheater, high failure rate and large air leakage, the boiler combustion system and coordinated control The system automatically put into question, starting from the specific causes of failure, the overall demonstration analysis, draw the corresponding countermeasures and formulate specific implementation plan, the system has been fully rebuilt. After the transformation of the system put into good control effect on the same type of unit leakage control system with a reference and reference.
