Schematic of the zero-atmospheric emissions 400 MW power plant
Grahic Jump Location
Zero-atmospheric emissions power plant data for base-case analysis. Notation: pressure—kPa, temperature—K, mass flow—kg/sec. Input Power=860.4 MW, LHV, electric power generated=528.2 MW, parasitic power=128.2 MW. Net electric power=400.0 MW, net LHV thermal efficiency=0.4649.
Grahic Jump Location
Net thermal efficiency of the zero-atmospheric emissions power plant as a function of inlet turbine temperature for three values of turbine isentropic efficiency (95%, 90%, and 80%). Data shown in this figure are obtained for the same inlet temperature of both the high-pressure turbine and the intermediate-pressure turbine.
Grahic Jump Location
Net thermal efficiency of the zero-atmospheric emissions power plant as a function of condenser pressure. The data were obtained for the base-case conditions shown in Fig. 2 and Table 1. The high-pressure turbine inlet temperature is 1089 K (1500°F), and the intermediate-pressure turbine inlet temperature is 1478 K (2200°F).
