Abstract
Method for cooling granular solid materials from a continuous curing facility having at least one area for burning a fuel to cure granular materials, wherein the curing of the granular materials, then the cooling of the cured granular materials is carried out in two consecutive steps, a first cooling step in a first cooler and a second cooling step in a second cooler, the method including: providing a cold air source for cooling the granular materials, the cold air source directly supplying air to the second cooler by blowing, and the air heated by the cured granular materials being used during the cooling as combustion gas for the burning area. All gases generated by the first and second coolers are routed to the burning area for use as a combustion gas, and the amount of cold air blown to the second cooler is adjusted to cover the air combustion needs.
