PERATION
The Baldwin™-Series Model 34C Heated Filter Probe is designed to
be mounted on a stack or duct for use in high particulate applications.
Its primary function is to provide a heated environment to maintain
sample gas temperatures above dew point and remove particulate
material from the gas sample. Model 34C features a standard 10
micron sintered stainless steel filter element, a external regulated
heater jacket, an integral calibration gas port on both sides of the filter
element, a NEMA 4 enclosure, and a single direct blowback system to
clean the filter element.
Mounting
The Model 34C is designed to be mounted directly on a stack or duct with a 1¼” Schedule
40 male pipe nipple. This pipe nipple can be screwed into a standard ASA flange, either flat
or raised face. The probe boot can be heat shrunk to the sample line to eliminate cold
spots.
Blowback
The Model 34C comes with a blowback air
accumulator tank and 2-way solenoid. To
operate blowback, connect a 50-90 psig
instrument airline to the blowback air
accumulator tank. The customer controls
blowback via a PLC or other means
determined by customer. The 2-way blowback solenoid is rated high temperature and 100
psig maximum pressure. The valve has a 1/8” orifice and the blowback instantaneous
flowrate is 14scfh.
Calibration
To operate calibration gas to the probe, open the user supplied calibration gas control valve,
adjust the cylinder pressure to >25 psig, and adjust the calibration gas flow rate to
approximately 20% above the highest gas sample flow rate.
