Abstract: As the coal power still remains dominant in China's current energy structure, the highly efficient and clean IGCC technology has demonstrated a wide application prospect in China. In this paper, the process flow of air separation technology, coal gasification, the high-temperature purification, and combined cycle technologies of five typical IGCC power plants with installed capacity greater than 250MW are analyzed. Particularly, the overall objectives, development stages as well as system parameters and the operation of the Tianjin IGCC project are described, which is expected to have certain reference value for the future development of IGCC technology in our country.

Key words: IGCC, coal gasification technology, green coal power, gas purification technology, gas turbine technology
