VERFAHREN ZUR ABWÄRMENUTZUNG IN EINER ANLAGE ZUR ZEMENTHERSTELLUNG UND ANLAGE ZUR ZEMENTHERSTELLUNG
The invention relates to a method for using the waste heat of a plant for producing cement and to a corresponding plant, wherein the plant has a heat exchanger (1), consisting of a series of cyclones (1a, 1b, 2, 3), at least one calciner (4, 5), a rotary tubular kiln (7), a clinker cooler (8) and a tertiary air duct (9) for carrying heated-up cooler air away from the clinker cooler (8) into the calciner (4), and wherein process gas is removed at the outlet of the calciner (5) and/or at the gas-side outlet of the first cyclone (1b) and/or at the rotary kiln inlet chamber (6), is fed to a first steam boiler (bypass boiler) (11) for the heating of steam for the purpose of subsequent conversion of heat into electrical energy and is then returned into the second or third cyclone (1a, 2) of the heat exchanger. The invention provides a removal of hot tertiary air from the tertiary air duct (9), a feeding of the tertiary air into a second steam boiler (tertiary air boiler) (20) for heating steam, and a feeding of the heated steam from the tertiary air boiler (20) to the bypass boiler (11) for further heating.
