Abstract
The present invention relates to a method for operating a cement plant, wherein a cement plant is selected comprising a primary cooler 41, a primary kiln 31 and a primary preheater 11, as well as a secondary calciner 22 and a secondary preheater 12, wherein a solids stream is fed into the primary preheater 11 and from the primary preheater 11 into the secondary calciner 22 and from the secondary calciner 22 into the primary kiln 31 and from the primary kiln 31 into the primary cooler 41, wherein a primary gas stream is fed from the primary cooler 41 into the primary kiln 31 and from the primary kiln 31 into the primary preheater 11, wherein the primary gas stream supplied to the primary preheater 11 has a first temperature, characterized in that a cold air stream is supplied to the primary preheater 11, wherein the cold air stream has a second temperature, the second temperature being lower than the first temperature.
