The Temperature Range Analysis for the Injection of Finely Divided Limestone Powder and the Experiment on Hydration Activity of the Calcinated Product

Jie Lu

Abstract

The thermodynamic calculation of the optimum temperature range for the decomposition of calcium carbonate and the desulfurization by calcium oxide is presented in this paper.The hydration activity of the calcinated product of limestone at different temperature was measured.The optimum temperature in the combustor for the injection of finely divided limestone powder is 950℃,The optimum temperature range is 846～1491℃.
