Techno-economic analysis on a new conceptual
1. Introduction. The temperature of boiler exhaust flue gas normally ranges from 120 to 150 °C in coal-fired power plant (CFPP). The heat loss of exhaust flue gas accounts for approximately 5080% of the total boiler heat loss and 38% of the total energy input of CFPP .This means that recovering waste heat from boiler exhaust flue gas could improve boiler efficiency and reduce emitted
