Claims (1)

Способ относится к металлургической, химической, строительной промышленности и может быть использован при эндотермическом обжиге карбонатсодержащего материала (известняка, доломита, магнезита, дунита). Для снижения энергетических и капитальных затрат при использовании мощных турбовоздуходувок в способе обжига кусковых карбонатных пород в двухшахтной прямоточно-противоточной печи, особенно большегрузной, включающем подачу воздуха в печь турбовоздуходувками в течение цикла, сжигание топлива в прямотоке, охлаждение извести в противотоке, отвод газообразных продуктов из печи и переключение шахт, согласно изобретению, сжигание топлива и охлаждение извести в цикле осуществляют поочередно. Предлагается также образующиеся во время охлаждения извести газообразные продукты отводить через обе шахты одновременно, а охлаждение извести в цикле проводить перед сжиганием топлива.The method relates to the metallurgical, chemical, construction industry and can be used in the endothermic roasting of carbonate-containing material (limestone, dolomite, magnesite, dunite). To reduce energy and capital costs when using powerful turbo blowers in the method of burning lumpy carbonate rocks in a two-shaft continuous-flow countercurrent furnace, especially a heavy-duty one, which includes supplying air to the furnace with turbo blowers during the cycle Furnaces and the switching of mines, according to the invention, the combustion of fuel and cooling of lime in the cycle is carried out alternately. It is also proposed to produce gaseous products formed during lime cooling through both mines simultaneously, and to cool the lime in a cycle before burning the fuel.
