IGCC

Integrated Gasification Combined Cycle (IGCC) is an emerging technology in power generation that utilizes low-quality fuels and is able to meet the most stringent emissions requirements. IGCC systems are extremely clean, and are much more efficient than traditional fuel-fired systems. IGCC uses a combined cycle format with a gas turbine driven by the combusted syngas from the gasifier, while the exhaust gases are heat exchanged with water/steam to generate superheated steam to drive a steam turbine. Using IGCC, typically 60-70% of the power comes from the gas turbine with IGCC, compared with about 20% using PFBC. The result is an integrated gasification combined-cycle configuration that provides ultra-low pollution levels and high system efficiencies.
