In one of our plants, we had frequent failures of castables in the bull nose area. The supplier (FLS), suggested us to go for an external cooling fan for the increasing the life. The trial is under observation

Cooling the cooler casing at the bull nose will not do anything to increase the life of the bull nose concrete or bricks. It will help to preserve the casing when the refractory lining is worn and the casing temperature rises.
