The efficiency of a coal-fired thermal plant is typically in the range of 30%-35%. In a combinedcycle gas turbine system running on natural gas, the maximum efficiency is in the range 45%-50%.
The integrated gasification combinedcycle (IGCC) is a promising electrical generation system which combines a clean coal transformation technique with a high efficiency combinedcycle system.
整体煤气化燃气-蒸汽联合循环(简称IGCC)是洁净煤转化技术和高效联合循环系统相结合的发电技术。
