Abstract

In this paper, a thermodynamic analysis of coal-fired thermal power plant is done at a particular inlet temperature (507.78 °C) and at different inlet pressures (122.16 bar, 123.14 bar, 124.12 bar, 125.10 bar, 126.08 bar, 127.06 bar and 128.04 bar). And then, correction factor curves for power and heat rate are generated for combined effect of inlet temperature/inlet pressures. These curves indicate that if inlet temperature and inlet pressure of steam (which is produced in boiler) vary, then power output and heat rate also vary. So these generated curves are used to prove that the designed/installed power plant is correct. Variations in the power/heat rate outputs occur because inlet conditions are not as per the designed conditions. These curves also help to identify the conditions at which the performance of the power plant is best. The paper concludes that 120 MW thermal power plant gives maximum power at 128.04 bar inlet pressure, whereas minimum heat rate can be achieved at 125.10 bar inlet pressure which is the designed pressure.

Keywords: Inlet temperature, Inlet pressure, Power output, Heat rate, Correction factor curves
