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.
