The Puertollano IGCC plant with Prenflo technology

The paper describes the Prenflo coal gasification process for integration in combined cycle power plants. This coal gasification process is based on entrained-flow principle using dry fuel dust feeding. The development of the Prenflo process was founded by the German Ministry of Research and Technology and the Commission of the European Union. The status of the world`s largest IGCC plant at Puertollano/Spain with a capacity of 300 MWe (net) will be presented. The plant is being built by ELCOGAS S.A., a consortium consisting of leading European utility companies from Spain, France, Portugal, England and Italy. The plant location, Puertollano, is a city approx. 200 km south of Madrid, at an elevation of approx. 700 m above sea level. Start-up of the IGCC plant at Puertollano is underway and the gas turbine has completed initial test runs with natural gas. The gasification section will begin commissioning in 1997. Stringent environmental regulations can be fulfilled by the new IGCC technology which at the same time achieves high efficiencies. Development trends in IGCC power plants will be discussed.
