摘要： A method and apparatus for automatically removing the noncondensable gases from the process stream congenerated in a Cheng cycle power plant. The gases are removed through a small diameter tube (66) joined at one end to a process steam line (28) and at the other end to a steam injection line (34) connected to the plant's gas turbine combustor (36).

摘要： A steam-injected free-turbine type of gas turbine. In order to avoid the necessity of redesigning the compressor/core turbine (22), the shaft (24) of the core turbine is modified to provide additional load output. As steam is injected into the system the resulting excess power of the core turbine is taken out of the system by coupling the compressor output shaft (160) with a load. Thus, the core turbine operates as a single shaft turbine in addition to the existing power turbine. A control (90) provides control of the load output of the two turbine output shafts so that the compressor/turbine stays in the matched operating domain.

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.
