Synopsis:

Fundamentals of heat processes focused on heat processes in process engineering, i.e. heat exchangers, evaporators and dryers.

Small review of fundamentals of thermodynamics and heat transfer (internal energy, enthalpy, entropy, thermodynamic diagrams, heat conduction, heat convection, dimensionless criteria).

Heat exchanger thermal design and rating. Thermal effectiveness method, Roetzel-Spang method.

Description of evaporators with natural and forced convection, falling and climbing film evaporators. Mass and enthalpy balance. Multistage evaporators and evaporators with mechanical and thermal recompression of vapours and with heat pump.

Drying and dryers. Description of contact, convective, radiation and spray dryers. Basic properties of dried material (sorption isotherms) and drying media (humid air). Static and kinetics of drying (drying curve).
