An analysis of spray evaporation in a high‐temperature environment: II. Calculation of the evaporative load distribution

This paper deals with the calculation of the evaporative load distribution in a spray of droplets suspended in an absorbing gas medium contained in a cylindrical column after a temperature profile for the gas has been assumed. Preliminary experimental data obtained for water sprays in an 8‐in. i.d. by 10‐ft. high pilot‐plant atomized suspension reactor at wall temperatures up to 800°C. are used to illustrate the method of calculation. The calculated results emphasize the importance of the physical characteristics of the spray, such as initial drop‐size and distribution, drop velocities and spray angle. They also indicate that the dynamics of such spray systems, as well as their heat and mass transfer aspects, require further elaboration.
