Abstract
Improvements in the apparatus for calcining powdered cement material and removing nitrogen oxides from the entire exhaust gases from the burning equipment. The apparatus comprises making the most of the sensible heat and fluidity of the cement material preheated by the burning equipment and using the material as a catalyst for diffusing and vaporizing the fuel, thereby producing reducing gases, and then bringing the reducing gases into contact with combustion gases from the kiln for stepwise combustion. The invention is also concerned with other improvements in the apparatus for carrying the method into practice.
