INNOVATIVE ENERGY & WATER CONSERVATION SYSTEM FOR POWER PLANT HAVING WET FLUE GAS DESULPHURISATION SYSTEM

摘要

The invention relates to an energy and Water Conservation system in a Power Plant. The said system comprises a corrosion resistant heat exchanger having an inlet and outlet for flue gases. The said inlet connected to the outlet of exhaust flue gases from ESP /bag filter and the said outlet connected to the inlet of flue gas desulfurization unit. A plate type heat exchanger having first fluid path having water outlet and water inlet and second fluid path having water inlet and water outlet. The said water outlet of first path connected to inlet of water circulation in the said corrosion resistant heat exchanger. The said water inlet of first path connected to the water outlet of the said corrosion resistant heat exchanger for intermediate water circulation. The said second fluid path water inlet connected to the boiler feed water supply for preheating in the said plate heat exchanger and the said water outlet of second fluid path connected to discharge outlet into the de-aerator tank.
