摘要： An improved shutdown procedure, which minimizes the potential for damage caused by steam condensation in the superheater section (20), combustion chamber (36) and turbines (50, 52) during the coast to halt of the engine maintains high temperatures until all the steam has passed through the system.

摘要： An improved procedure for cold start-up of closed loop boiler set and Cheng cycle system wherein the venting step, the boiler swelling problem and blowdown step of the conventional start-up are eliminated by use of an external pressure source (40) to increase the operating pressure in the evaporator section (12) which minimizes premature phase change and accompanying volume increase.
