Abstract

Low Pressure Economizer plays an important role in reducing exhaust gas temperature & enhancing the thermal efficiency. A 60 MW Thermal Power Plant used to ensure its safe operation and the optimal Economic condition. We put forward to Design of LPE in two Cases by exergy analysis of the various components of the power plant. There are two cases for installing LPE: One, the installation of LPE between Condenser & low Pressure heater, second, the installation of LPE between high pressure heater and low pressure heater. According to the Exergy analysis, it’s found that the LPE between the Feed water Heater is more effective then Case-1. It proposed to reduce the flue gas temperature from 155oC to 131oC. Thermal Design of LPE defines the area of the heat exchanger found to be 2.56 m2. Compact type finned tube heat exchanger is more suitable for gas to liquid pass heat exchanger for low pressure economizer. It’s proposed to reduce the coal consumption rate and improve the performance of the plant. Also reduce the CO2 Emission of the flue gas.
