Title:
FURNACE DAMPER CONTROL SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2010/093894
Kind Code:
A3
Abstract:
A furnace damper control system and method thereof including a furnace having at least one opening through which electromagnetic radiation from within the furnace may be sensed, an exhaust duct capable of receiving an exhaust gas stream emerging from the furnace, and a controllable damper capable of adjusting the pressure in the exhaust duct. A sensor is capable of sensing electromagnetic radiation through one or more of the openings of the furnace and generating a sensor signal corresponding to the electromagnetic radiation, and a processor is capable of processing the sensor signal and generating a monitoring signal responsive to a parameter of the electromagnetic radiation indicative of furnace emissions. A controller is capable of controlling the damper responsive to the monitoring signal indicative of the furnace emissions.
