Installation
Fig. 1 shows a suggested installation utilizing a 1” coupling welded to the generator wall. The
hole through the insulation must be at least 1 ¼” in diameter and axially aligned with the
coupling to avoid interference with the Bazooka™ well which has an O.D. of 1.050”. For existing
installations with larger fittings, use a bushing to reduce the diameter to the 1” female required
by the probe gland. Provide for about 1 SCFH of reference air, 6-10 SCFH of burnoff air, and 2 –
3 SCFH of sample from the endo manifold or sample from individual retorts. The probe should
be inserted to a depth such that, at equilibrium, the probe temperature is between 1400ºF
(760°C) and 1700ºF (926.7°C), preferably at 1550ºF (843.3°C).
IMPORTANT!
Zirconia is thermal shock sensitive. Insert into hot atmosphere no faster than 2” (51mm) per
minute (after first 4 inches or 101 millimeters).
Temperatures above 1500 °F (815.6°C) will prevent sooting from the sample atmosphere.
1550 °F (843.3 °C) is an optimal temperature to ensure that the sheath is not exposed to
excessive temperatures, and this temperature will provide optimal life of the sheath and its
components.
