A lime kiln produces quicklime when limestone is calcinated. To achieve this the rotary kiln must reach a temperature upwards of 1000°C. Refractory bricks are designed to reduce thermal loss and the consumption of energy. Kiln lining refractories improve insulation, reduces maintenance costs, improve safety while keeping downtime to a minimum.

One of the primary reasons for refractory brick spalling in lime kilns is thermal cycling. Lime kilns operate at high temperatures, typically ranging from 900°C to 1200°C. The continuous heating and cooling cycles cause the refractory fire bricks to expand and contract, resulting in thermal stress.

Overall, the use of refractory bricks in kilns can improve performance, reduce downtime, and improve energy efficiency, ultimately leading to cost savings and …
