Full scale calcination of significant calcium limestone employing standard methods was executed in the batch method Experimental Lime Kiln (ELK). The ELK is supplied to monitor temperature, air movement and gas compositions and in addition has substantial insulation to guarantee minimal lateral Strength reduction through burning. Inner kiln wall temperatures of nearly 550oC, and kiln Main temperatures of 850oC, within the choice of calcium carbonate disassociation are already reached for various hrs with predictable temperature/time gradients. A mixed feed stable gas : stone ratio of 1:9 was utilized causing limestone conversion to quicklime of seventy five% ± 9. The heat stability performance is about forty five%.
