Effects of Calcination Conditions on the Properties of Lime


Experiments were made to define quantitatively the effects and interactions of the time of calcination, the temperature of calcination, and the particle size of a pure limestone upon the properties of the calcine that may affect the absorption of sulfur dioxide from flue gases. Response surfaces were derived for the degree of calcination, pore volume, density, crystallite size, and capacity to absorb sulfur dioxide as functions of the calcination conditions. It is predicted that wide variation in the degree of utilization will occur over relatively narrow ranges of retention time and injection temperature likely to be encountered in attempts to control sulfur dioxide emissions by injecting limestone in power plant furnaces.
