NETE Control of Total Radiation in an Industrial Furnace by Optical Sensing of Flame Emissions

Abstract

In this work, we show the results of a control
system synthesis of total radiation Radt in an industrial furnace,
based on successful nonlinear modeling of this optical combustion
diagnostics variable. As a real-life example, we describe the
closed-loop solution applied to the case of a ladle furnace
preheating process in a steel manufacturing plant. We present
total radiation Radt controllers design taking advantage of the
nonlinear modeling results, for broad and narrow range
controllers respect to the process input of fan speed rate.
