· Boiler Refractory dry out is to ensure proper drying curing of refractory applied on furnace and other components. The refractory usually undergoes considerable chemical changes during initial heating. Controlled heating through these reactions ensures maximum strength. While heating there must be free air flow over the system to ensure removal of moisture.

Heat recovery analysis of boiler furnace using refractory
· For this case castable refractories are used. Refractory structures used in power boilers use stainless steel anchors for reinforcement. Failure of refractories in the form of cracks leading to falling off them were observed in operation. Often the refractories themselves are not the cause of failure rather the reinforcing metallic anchors were found to be the one. Wrong choice of material inadequate design of refractory structure over temperatures leading to anchor material deterioration are among the main reasons for anchor failures.
