Design and Analysis of Flue Gas Waste Heat Recovery System for Refrigeration In A Thermal Power Plant

Authors(2) :-Prashant S. Mawade, Prof. K.M.Watt

Huge amount of energy wasted through the flue gas in thermal power station causes a great concern in recent years. Discharging hot flue gas in the environment is not only a wastage of energy but also increases the rate of global warming. Efforts are given world-wide to harness the energy for useful purposes. The main objective of this research work focuses on tapping the unused heat energy from the flue gas in a 270 MW thermal power plant and using the same for refrigeration purpose for the large cooling load requirements in a thermal power plant. The waste heat of flue gas is utilized in vapour absorption refrigeration plant by using gas to liquid multi-pass cross flow heat exchanger that is placed in the existing space between boiler and chimney. Vapour Absorption Machine doesn’t require very high temperature and also requires a little operational power as compared to Vapour Compression Refrigeration Machine. Hence, this work intends to replace existing Freon-12 refrigerant based Vapour Compression Refrigeration System during the thermal power plant operational hours and thus preventing ozone depletion. This research work also aims in minimizing global warming and also high suspended particulate matters based air pollution by reducing temperature of exhaust gas emitted to the atmosphere. The project work selects the most economic design of a heat exchanger as the final design and analyses the design by a ANSYS software on detailed design parameters of gas to liquid multi-pass cross flow heat exchanger.
