Natural gas-fired combined cycle (NGCC) systems

A.D. Rao,     University of California, USA

Abstract:

A combined cycle combines two power cycles in series to obtain a high overall thermal efficiency, significantly higher than the individual efficiencies. This chapter discusses utilization of a Brayton cycle or gas turbine for the topping cycle and a steam Rankine cycle for the bottoming cycle. The size of a combined cycle may range from less than 10 MW to in excess of 500 MW while using a single gas turbine. In addition to having thermal efficiencies exceeding 60% natural gas lower heating value (LHV) basis with a ‘J class’ gas turbine with a nominal 1600 °C turbine inlet temperature (Ito et al., 2010), outstanding environmental performance, ...
