Abstract

Способ обжига известняка может быть использован в металлургии, строительной и других отраслях промышленности. Способ включает предварительную тепловую обработку в шахтной печи и окончательную - во вращающейся печи. На стадии предварительной обработки в шахтную печь подают газы, отходящие из вращающейся печи. Способ отличается тем, что газы, отходящие из вращающейся печи, смешивают с дополнительными высокотемпературными продуктами сгорания топлива, сжигаемого в выносной топке, и полученную газовую смесь с температурой выше начала декарбонизации материала подают в шахтную печь, в которой производят декарбонизацию до степени 30-85%.The method of burning limestone can be used in metallurgy, construction and other industries. The method includes preliminary heat treatment in a shaft furnace and the final one in a rotary furnace. At the pretreatment stage, gases are drawn from the rotary kiln into the shaft furnace. The method is characterized in that gases exhaust from a rotary kiln are mixed with additional high-temperature combustion products of fuel burned in a remote firebox, and the resulting gas mixture with a temperature higher than the onset of decarbonization of the material is fed into a shaft furnace in which decarbonization is performed to a degree of 30-85% .
