Balanço térmico do forno rotativo e do resfriador da fábrica Elizabeth Cimentos Ltda

Abstract

The manufacture of cement, though very ancient, was only patented in 1830 by the Englishman Joseph Apsdin, who called it "Portland Cement". The cement is a hydraulic binder consisting of a mixture of clinker, gypsum and additives. In specific proportions of limestone and clay, the flour formed undergoes sintering at high temperatures and subsequent abrupt cooling, resulting in the formation of the main cement component, clinker. The present work was carried out at the Elizabeth Cement Factory, located in the city of Alhandra - PB, at the clinker stage, where a thermal balance of the rotary kiln and the cooler was realized in order to improve the heat efficiency and the fuel consumption of the process.
