Study on IGCC system characteristic with off-design gas turbine

Xiaoli Chen

Abstract

Gas turbine is the key equipment in IGCC system,and its performance affects the whole system directly.The system model of 200 MW IGCC was established using Thermoflex software,the IGCC system off-design characteristics was mainly analyzed with gas turbine at 40%～100% load.The control modes of falling gas turbine load were analyzed through the changes of the initial temperature of the gas turbine and the IGV of the compressor.From the view point of the system,the changes of the main performance parameters of the IGCC system were studied with off-design gas turbine.The results will offer some reference for IGCC plant design and operation in the future.
