Inorganic salts are used in the lime industry to alter the physical properties of calcined limes. Such physical effects on limestone calcines seem to form the basis for enhanced ability of stones to react with sulfur dioxide. This interaction, particularly in regard to using limestones more efficiently to reduce environmental contaminants in fluidized-bed combustion off-gas, is investigated. Application of sodium chloride addition to fluidized-bed coal combustion would increase the sulfur capacity of unreactive limestone and reduce the quantity of limestone needed and solid waste produced in meeting SO2 standards.
