Thermal efficiency fired combined cycles

Supply side efficiency measures. Here we mean primarily increasing the efficiency of electricity production. Natural gas combined cycle power plants (NGCC) emit less C02 than single-cycle coal-fired power plants first, because natural gas emits about one-half the amount of C02 per fuel heating value than coal, and secondly, because the thermal efficiency of combined-cycle power plants is in the 45-50% range compared with the 35-38% range of single-cycle plants. In the... [Pg.165]

In general, the major driving force for all advances in thermal power plants and NPPs is thermal efficiency and generating costs. Ranges of gross thermal efficiencies of modem power plants are (1) combined-cycle thermal power plants (up to 62%) (2) supercritical-pressure coal-fired thermal power plants (up to 55%) (3) C02-cooled reactor NPPs (up to 42%) (4) sodium-cooled fast reactor NPPs (up to 40%) (5) subcritical-ptessure coal-fired thermal power plants (up to 40%) and (6) modem water-cooled reactors (30—36%). [Pg.33]
