Abstract :
It is well known that common boilers and similar thermal processes for the bulk heating of liquids can become unstable, when closed-loop controlled, if the controller and/or the controlled-variable transducer location are chosen arbitrarilly. This paper describes a new facile technique for readily determining the boundary conditions for stability when selecting controllers or locating transducers. The presentation is intended for the professional engineer engaged in the control of boilers and liquid-heating processes in industry.
