摘　　要：本文分析回转式空气预热器造成漏风的原因,设计并实现了STD-BUS为主控制机的预热器间隙控制系统,解决了在400℃高温区非接触式测量间隙值的难点,所构成的闭环调节系统实时检测并调整间隙,同时可处理多路故障信号,及时发出信号完成显示、报警及打印等多种功能,系统研制成功为大型电站锅炉节能提供了新的途径。A proposal using STD—BUS computer to control sealing interstice non—contact and continually within the area of elevated temperature is put forwarded in the paper. STD—BUS computer, with high speed, real—time control and correct detection, is used to improve traditional detective method of sealing interstice, to reduce air leak and to increase heat efficiency. It is a new way to make use of the after—heat of power station boiler.
