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 theopen bottom end. The upper opening is provided in gaseous communication with thegas analyzer, and a filter is removably positioned across the upper opening to prevent dust and other particulate matter entrained in the sample off-gas from moving through the upper opening and into the gas analyzer. To cool the sample gas and prolong the filter life, part of the probe is provided with a double sidewall construction so as to define a partitioned annular chamber extending about at least part of the gas passage along which cooling fluid may move.
