Summary

The course focuses on understanding the basic thermal engineering principles and fundamentals of heat transfer and hydromechanics. It also focuses on the thermo-physical properties of materials in the context of their heating and cooling. The basics of heat transfer in the furnace environment, methods of heating materials, calculation times for heating materials, heating in controlled atmospheres, and rapid heating are described. An overview of the furnace linings used, heat exchangers and methods of measuring basic parameters in furnaces is also given. Overview of furnace types and their design parameters. Practical demonstration of heating and cooling of materials.
