Stability in Electric Process Heating

In an important and widely used class of industrial applications of electric process heating, instability can occur if the parameters of the process and its controller are selected arbitrarily. This phenomenon has long been familiar to designers of these processes, and over the years empirical rules have evolved intended to avoid incorporating such instabilities into the design. An analytical approach to determine the criteria for stability in these processes is presented and developed to provide new facile design techniques. These new methods are intended for the professional engineer engaged in the design of such industrial manufacturing processes or in similar applications of electric process heating.
