Boiling heat transfer is a complex phenomena that is widely encountered in chemical process operations. The problems one faces in evaluating the reliability of a reboiler design, or in judging the effect of modifications of process conditions on reboiler operation, can be complex. To carry out such evaluations, it is necessary for engineers to perform some calculations to determine: 1. heat transfer coefficients in convection boiling, 2. temperature difference for the onset of nucleate boiling, 3. critical heat flux or critical temperature difference, 4. minimum temperature difference between heat transfer surface and fluid saturation temperature for film boiling, and 5. heat transfer coefficients for the film boiling region.
