Heat and mass transfer provide the basis for the design and optimisation of all processes in high-temperature process engineering. This work examines in detail not only the fundamentals, but also, with special emphasis, applications in rotary kilns, shaft furnaces, tunnel furnaces and roller-hearth furnaces. There is therefore a particular focus on radiation exchange and on the cooling of metals using liquids and nozzle arrays. Comprehension is aided by numerous examples drawn from practice. Content: Modes of heat and mass transfer, Steady heat conduction, Thermal resistances, Thermal conductivity, Convective heat transfer, Vaporization and Condensation, Heat exchangers
