Method for controlling the operation of a rotary kiln for cement manufacture

摘要

The invention relates to a method for controlling the operation of a rotary kiln for cement manufacture, wherein the O2 content and the NOx content of the kiln exit gases is measured and the free lime content to be expected in the clinker is determined by interpolation in a previously established field of characteristic lines. Such a method is distinguished by a rapid response time and clear relationship with product quality.
