Thermal spelling, Chemical Engineering

Assignment Help:

Thermal spelling: The breaking or cracking or peeling off the refractory is known as spelling. A good refractory must show a good resistance to thermal spelling. Thermal spelling can be decreased by minimizing the development of internal stress by:

(1)         Using refractory with high porosity, good thermal conductivity and low coefficient of expansion.

(2)         Avoiding sudden temperature changes.

(3)         Proper furnace design
