ABSTRACT:
A method and apparatus for thoroughly dispersing powdered material in a combustion chamber of a furnace in combination with a suspension preheater and a kiln to improve combustion efficiency. The material is introduced as a free falling stream in the upper zone of the combustion chamber and is contacted in the upper zone with recycled gases from a cooler and a second gas introduced at a higher velocity than said recycled gases, whereby the powdered material is thoroughly dispersed throughout said combustion chamber and heat exchange between the material and gases is enhanced.
