Abstract:
A method for producing power comprising the steps of:a) supplying clinker from cement production apparatus to a grate cooler for cooling the clinker; b) extracting hot air from the grate cooler and supplying it to a electrostatic precipitator for extracting particulate matter from said hot air; c) supplying filtered air exiting said electrostatic precipitator to an air-heat transfer fluid heat-exchanger for heating a heat transfer fluid; d) vaporizing working fluid in a vaporizer using heat in the heated heat transfer fluid and producing vaporized working fluid and heat depleted heat transfer fluid; e) pre-heating working fluid using heat in said heat depleted heat transfer fluid; f) supplying vaporized working fluid produced in said vaporizer to a turbine for producing power; g) supplying vaporized working fluid exiting said turbine to a working fluid condenser that condenses said vaporized working fluid exiting said turbine and producing working fluid condensate; and h) supplying said working fluid condensate to said vaporizer.
