AUTOMATION/CONTROL LOGICS FOR SAFE AND EFFICIENT WORKING OF FFES

Abstract

The main objective of the paper is to discuss the automation & control logics required for Falling Film Tubular evaporators operation. What are the potential benefits of these controls and why the same are necessary for the smooth running of FFE’s. How these controls improve the efficiency of the equipment and save from accidents like choking of tubes, entrainment etc. control logics required to maintain juice levels, emergency water, juice circulation flow, exhaust steam pressure and vapour temperature are discussed in the paper. How these controls help to make these evaporators monitoring easy and accessible. A review of the suitable instrumentation for better working and control is also a part of paper.
