Analysis of Energy and Economic Advantages of Dolomite Clinker Production from Industrial Wastes

Ukraine has accumulated a large amount of industrial waste. The paper presents the results of the behavior of a mixture of waste dolomite and waste coal during heating. During the operation of enterprises a large amount of “waste” - small fractions of dolomite, which are in the dumps, has been accumulated. Waste is a valuable raw material for production of dolomite binders - lime and cement. Dolomite waste is used for comparison. Comparative analysis showed: energy consumption decreases. Reduction of energy costs indicates reduced fuel consumption for the process. The analysis of reduction of operational costs as a result of replacement of high-calorie fuel by coal preparation waste is carried out. Reduction of operational costs is shown when using dolomite waste instead of dolomite. The economic calculation of reduction of operational costs as a result of replacement of high-calorie fuel by coal preparation wastes is carried out.
