That is why a tightly packed kiln will must be fired for less time than the usual 50 percent-loaded kiln.  A tightly packed kiln will radiate additional warmth the moment it reaches a certain temperature.

Complete scale calcination of large calcium limestone utilizing traditional approaches was executed while in the batch procedure Experimental Lime Kiln (ELK). The ELK is supplied to watch temperature, air stream and fuel compositions and likewise has important insulation to guarantee minimum amount lateral Power reduction all through burning. Inside kiln wall temperatures of as many as 550oC, and kiln Main temperatures of 850oC, throughout the number of calcium carbonate disassociation have already been obtained for numerous hours with predictable temperature/time gradients. A blended feed stable gas : stone ratio of 1:9 was employed causing limestone conversion to quicklime of 75% ± 9. The heat equilibrium efficiency is approximately 45%.
