Exergy Analysis of 120MW Thermal Power Plant with Different Condenser Back Pressure and Generate Correction Curves

Abstract

The thermal power plants are used to generate power. The thermal power plants are designed based on required conditions (like a good quality of steam, pressure and temperature of steam e.t.c.), but actually inlet conditions are not as per the designed conditions. In practical situations, when power plants are installed there are lots of constraints. This tends to reduce or increase output power and heat rate of thermal power plants. Due to these conditions, the designed power and heat rate are never achieved. Variations in the power outputs from plant are always a matter of disputes. So the correction curves for power and heat rate are generated for different conditions of condenser back pressure. These curves indicate that if operating conditions vary, then power output and heat rate also vary. This paper deals with the generation of the correction curves for 120 MW thermal power plant.
