セメントロータリーキルン用燃料燃焼装置及び燃焼方法
Document Type and Number:
Japanese Patent JP3623130
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rotary kiln combustion apparatus and a combustion method useable without deteriorating the quality of an article calcined in a rotary kiln without pulverizing combustible solid particulate substance. SOLUTION: In a rotary kiln cylindrical burner there are provided a group of inside primary air injection hole 13b disposed on a concentric circle and partitioned from each other, a group of fuel/conveyance air mixture injection holes 14b, and a group of inside primary air injection holes 15b. Further, one combustible solid particulate fuel injection hole 16a is disposed inside the injection holes 15b, and primary air and a fuel are combusted through the injection holes to form a flame highest temperature region while feeding the secondary air into the rotary kiln. The particulate fuel injected from the injection hole 16a is passed through the region into combustible gas which is then combusted.
