Abstract

Abstract: Fast cooling device is a kind of auxiliary equipments used when highpower steam turbine shutdown. The preparation before put to usage, operation procedures and regulation bases for usage were introduced in detail, the problems to be noticed in using of fast cooling device were analyzed. The calculation shows that great economic benefits can be obtained by using of fast cooling device.

Key words: steam turbine, fast cooling device, sliding-parameter, differential expansion, axial displacement
