GE, Exergy Move Forward with Kalina Cycle Development.
AMSTERDAM, The Netherlands--(BUSINESS WIRE)--May 22, 1995--GE Power Systems (GEPS GEPS General Electric Power System ) is in the process of identifying a site for a commercial-scale plant to demonstrate the Kalina Cycle The Kalina cycle is a thermodynamic cycle for converting thermal energy to mechanical power which utilizes working fluid comprised of at least two different components and a ratio between those components is varied in different parts of the system to increase thermodynamic as a highly efficient, cost-effective bottoming cycle for GE combined-cycle power systems, GE said today at Power-Gen Europe '95.
"We've established a team to develop the demonstration plant, and we are working with several candidate hosts," said James Corman, general manager, GE Power Generation Systems. "Our objective is to have the plant in operation by 1998." The demonstration plant is expected to be in the 40-140 megawatt meg·a·watt

GE has a worldwide exclusive licensing agreement with Exergy, Inc. of Hayward, CA to develop and market the Kalina Cycle technology, which GE-Exergy studies indicate will increase combined-cycle efficiency by 2-3 percentage points in commercial-scale power plants, compared with a three-pressure reheat Re`heat´

For example, these efficiency advantages for the Kalina Cycle would apply to GE's current F technology gas turbines as well as to GE's just-introduced H technology combined-cycle system. Increases in efficiency can mean millions of dollars in fuel cost savings over the life of a power plant.

Corman said that recent system advances by the Exergy/GE team "have significantly improved the economics of the Kalina Cycle. An objective of the commercial demonstration project is to confirm the operational and maintenance characteristics of a Kalina Cycle power plant."

In power generation alone, GE combined-cycle plants have accumulated more than four million operating hours.
GEPS is one of GE's major businesses and is the world's largest supplier of power generation equipment. GEPS has three regional headquarters serving the global market -- GEPS Asia in Hong Kong Hong Kong (hŏng kŏng), Mandarin Xianggang, special administrative region of China, formerly a British crown colony (2005 est. pop. 6,899,000), land area 422 sq mi (1,092 sq km), adjacent to Guangdong prov. , GEPS Europe in Florence, Italy and GEPS Americas in Schenectady, N.Y. -- in addition to local offices and service centers worldwide.
