Abstract

1483166 Preheating cement raw meal; waste heat boilers FIVES-CAIL BABCOCK 24 Dec 1975 [27 Dec 1974] 52921/75 Heading F4B In a cement plant comprising a rotary kiln, and a multistage preheater utilizing the waste gases from the kiln, a waste heat boiler is arranged between two preheater stages to be heated by the furnace gases. Cement raw meal is preheated in cyclones 1, 2, 3, 4, sintered in kiln 12 and the clinker is cooled at 14. A boiler 16 receives gases from the cyclone 2 and discharges them to the cyclone 1, and the boiler preheater is heated by gases from the cyclone 1. Part of the fumes from the cyclone 2 are directed to a drier-crusher 24, which also receives heated air from the cooler 14. The steam from the boiler may be used to drive a turbine generator. The proportion of the gases fed to the boiler is controlled by a valve 28 in the line supplying the drier, and the boiler is arranged to be heated to more than 400‹ C.
