Heat Transfer in a Gas-Liquid Contact Evaporator
SINOPSIS
Heat transfer between a gas jet and evaporating liquid, with a nozzle cross-section for gas outflow being positioned differently with respect to a liquid level in the physical model of the apparatus containing a submerged burner, is studied experimentally. It is found that in the case when the nozzle outlet cross-section lies above the liquid level two flow modes - jet and bubbling - are possible. Empirical relations for calculation of the temperature of a vapor-gas mixture at the apparatus outlet are obtained for each mode. The results of the study are used in the development of energy-saving technological schemes of processing wastes of potato starch production and evaporative decontamination of mineralized sewage.
