Continuous selective heating of the solid phase of a dispersion medium in a unit constituted by heater and valve-pulsed mass–heat-exchange apparatus

A new technique is suggested for the continuous and selective heating of the solid phase in a flowing dispersion. This technique is implemented in a heater–valve-pulsed apparatus unit. Mathematical models are developed for the cocurrent and countercurrent designs of the heater. Analytical solutions are obtained for the model equations, and parameters governing the continuous selective heating of the solid phase are determined. A design algorithm is suggested for the unit.
