Advanced technology combined cycle
The General Electric {open_quotes}H{close_quotes} technology combined cycles represent the power generation equipment with the most advanced technology that is available today. These systems can achieve 60% net thermal efficiency when burning natural gas and 50% when firing coal in Integrated Gasification Combined Cycle (IGCC) systems. Their environmental impact per kW of generation is the lowest of all fossil fuel-fired systems. These efficient combined cycles are the result of integrating the advanced technology, closed loop steam-cooled 60 Hz MS7001H and 50 Hz MS9001H gas turbines and advanced technology steam turbines with reliable steam cycles using unfired, multiple pressure, reheat heat recovery steam generators (HRSGs). These advanced technology combined cycles are also available with air-cooled MS7001G and MS9001G gas turbines with 58% net thermal efficiency. The preferred configurations are the STAG 107H and STAG 109H single shaft combined-cycle generation systems. This configuration has outstanding operating characteristics and it complements the cycle integration between the steam-cooled gas turbine and the steam bottoming cycle. The systems are designed for base load generation of mid-range peaking duty cycles, including daily start-stop operation.
