Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Regulation of thermal regime concurrent-countercurrent dryers O.M. CHAIKIN, M.P. TSYGANKOV The features controlling the thermal regime dryer drum with a concurrent-countercurrent (divergent) movement of heattransfer agent in the drum are discussed. A scheme of automatic control, allowing to avoid the adverse effects of the motion of gas flows on the dynamics of the system of stabilization temperatures is suggested. Key words: automation, control, dryer, drum dryer, heattransfer agent. E-mail:cigg@rambler.ru
