Abstract: The rapid hot start method of the unit of capital construction and the unit operating in lone island mode without auxiliary steam source was introduced and analyzed. Comparing with the normal hot start method, the new method can shorten the accident time and increase the economical efficiency of the unit. In addition, this method plays an important role for prevention of freezing of direct aircooled system in winter.

Key words: without auxiliary steam source, hot start, direct air-cooled, economical efficiency
