摘要: Abstract A theoretical study of power generation from oxidation coal by supercritical water (SCWO) is presented. Two versions SCWO plant are compared to two the most efficient conventional processes: pulverised plants and pressurised fluidised bed plant. The effects steam pressure temperature on produced (Wp), consumed (Wc) net work (WN) calculated in order compare efficiency these for same conditions. Enthalpies have been using residual enthalpies Peng–Robinson equation state. Calculated results show that 5% higher than other plants, due fact no air surplus necessary complete combustion because direct heating. Energetic increases more quickly with plants. effect different: until 30 MPa efficiencies increase but when pressures beyond MPa, decrease
