Abstract

Abstract: The composition of the IGCC system was introduced. The selection of air separation process flow and the connection mode of air separation device with gas turbine system were expounded. Based on this, the influence of air separation unit integrated coefficient on the gas turbine and steam turbine was analyzed; and a mathematical model and calculation conditions were established. Under the calculation conditions, it was determined that the air separation unit integrated coefficient Xas=0.6 is the optimal extraction ratio of air compressor.

Key words: integrated gasification combined cycle (IGCC) system, air separation system, air separation unit integrated coefficient, designed condition
