That is why a tightly packed kiln will have to be fired for less time than a 50 %-loaded kiln.  A tightly packed kiln will radiate much more heat once it reaches a particular temperature.

Comprehensive scale calcination of high calcium limestone utilizing traditional methods was performed during the batch approach Experimental Lime Kiln (ELK). The ELK is supplied to monitor temperature, air movement and fuel compositions in addition to has sizeable insulation to guarantee bare minimum lateral energy reduction in the course of burning. Interior kiln wall temperatures of around 550oC, and kiln Main temperatures of 850oC, inside the range of calcium carbonate disassociation are attained for several hrs with predictable temperature/time gradients. A combined feed good fuel : stone ratio of one:nine was utilized leading to limestone conversion to quicklime of seventy five% ± nine. The heat stability performance is about forty five%.

The exact same or identical response can happen which has a sudden massive drop in secondary air temperature, or when an excessive amount of air (massive proportion of extra air) is introduced in to the kiln by excessively higher I.D. supporter velocity. Both of such occurrences can result in a decrease in flame temperature.

This has two effects.  To begin with,  pressure will Establish up while in the kiln and heat will be dispersed far more evenly.  This assists to make a much more uniform temperature.  Secondly, it reduces the quantity of oxygen in the kiln, developing the reduction atmosphere described previously.
