6 HEAT RECOVERY FROM EXHAUST GAS IN A SPRAY DRYER CHEMICAL INDUSTRY7 WASTE HEAT RECOVERY FROM CHPDrying occurs by effecting vaporization of the liquid by supplying heat to the wet feedstockHeat may be supplied by convection direct dryers by conduction contact or indirect dryers.

PERFORMANCE of HEAT RECOVERY SYSTEM FOR A SPRAY DRYER.

A factorial experimental design was used to study the effect of exhaust heat recovery air flow rate and outlet temperature on the energy consumption of a spray dryerA commercialscale cocurrent flow dryer with pressure atomization was used to dry 15 wt sodium sulfate solutionsThe inlet air to the dryer was preheated by using a shelland.

Air heating by heat recovery using airtoair heat exchangers AHX and heat pumps HP was analyzed for a typical spray dryer with inlet ambient air heated to 200 176C and exhaust air with dry bulb of 76 176C and dewpoint of 38The HP design is a tradeoff between greater heat recovery and lower COP as evaporation temperature decreases.

An increase in the height of the spray dryers for RR 50 and 80 is 1786 respectively compared to the base caseThe economic analysis is carried out for a spray dryer with a revised height of the drying chamber to account for reduced driving potential due to direct heat recovery as shown in Fig.
