  • Flame image analysis for furnace combustion control
    Patent number: 10991087
    Abstract: Operation of a combustion control system of furnace is controlled by image analysis, outside of the furnace or within the furnace, of a flame produced by combustion within the furnace, to correlate the image with carbon monoxide content of the flame, and adjustment of the oxygen and/or fuel flow into the furnace in response to the correlation.

  • Method and apparatus for sampling and analysis of furnace off-gases
    Patent number: 5777241
    Abstract: A furnace system includes a furnace and a furnace monitoring and control system having a gas analyzer for analyzing the composition of furnace off-gases, and a sampling tube or probe used to obtain a high temperature off-gas sample for delivery to the gas analyzer. Gas samples are drawn to the gas analyzer, via the probe, by a vacuum. The probe is formed as a generally cylindrical or polygonally shaped hollow tube, which when mounted in the system defines a generally vertically extending elongated gas passage along which sample gas is drawn, and whereby sample gas flow in the passage is in a generally vertical direction. The probe is provided with upper and lower openings which extend into the gas passage. The lower opening is provided in gaseous communication with the furnace off-gas stream and is formed so as to permit the substantially unhindered movement of particulate matter, such as dust, downwardly along the gas passage and outwardly through the open bottom end.
