A method for producing power, in accordance with the present invention, comprises the steps of: supplying clinker form cement production apparatus to a grate cooler for cooling the clinker; and extracting hot air from the grate cooler and supplying it to a filter e.g. an electrostatic precipitator or bag filter. When an electrostatic precipitator is used for extracting particulate matter from the hot air supplied from the grate cooler, the filtered air exiting the electrostatic precipitator is supplied to an air-heat transfer fluid heat- exchanger for heating the heat transfer fluid. A working fluid is vaporized using heat in the heated heat transfer fluid and vaporized working fluid and heat depleted heat transfer fluid is produced. Heat in the heat depleted heat transfer fluid is used to pre-heat working fluid while vaporized working fluid produced in the vaporizer is supplied to a turbine for producing power. Vaporized working fluid exiting the turbine is supplied to a working fluid condenser that condenses the vaporized working fluid exiting the turbine and produces working fluid condensate that is supplied to the vaporizer. Preferably, the method includes supplying the vaporized working fluid exiting the turbine to a recuperator that heats working fluid condensate supplied from the working fluid condenser prior to supplying the working fluid condensate to the vaporizer. Furthermore, preferably, the working fluid condensate is supplied to a pre-heater that preheats the working fluid condensate and produces preheated working fluid that is supplied to the vaporizer.
