Impact of Burner Design on Combustion Efficiency

摘要

Burner impacts on the lime calcination & kiln operation:1. Controls flame shape and the kiln temperature profile:1.1. Affects directly the lime quality → Residual carbonate & reactivity1.2. Flame too short → Excessive temperatures in burning zone, lime surface overburned and reactivity reduced. Risk of refractory failure.1.3. Flame too long → insufficient radiant heat transfer in calcining zone, higher back-end temperature and lower thermal efficiency Risk of rings and build-ups formation due to lazy and unstable flame (temperature variations) dusty kiln..
