Thermohydrodynamics of a Spray Drying Installation with Convective-Radiative Energy Supply

Results are presented of experimental investigations of the working parameters of a spray drying installation with a combined supply of heat by convection and infrared radiation, the density of the heat flux in the infrared radiation device, and the intensity of mixing the gas phase. The analysis of the obtained data shows that the supply of heat to the chamber by infrared radiation and the latter′s impact on the liquid′s spray pattern makes it possible to increase signifi cantly the moisture intensity of the chamber, to decrease the heat rate for evaporation of moisture, and to raise the installation′s efficiency.
