System and method for monitoring and controlling furnaces

Abstract

A furnace monitoring system for monitoring a furnace over a span of time during furnace operation, including a thermal imaging apparatus, the apparatus is disposed outside of the furnace and at a distance from the exterior of the furnace to generate field signals of the furnace; a signal processing unit configured and programmed for receiving the field signals and generating a temperature map of the exterior of the furnace; and a means for displaying the temperature map locally or remotely. Wherein in that the furnace monitoring system is a system for monitoring the furnace over a span of time during furnace operation and in that the generated temperature map is divided into several zones, which correspond to different components of the furnace selected from burner, viewing port for burner observation, charging port, discharging port and flue gas channel.
