Batch Furnace Multi-gas Process Analyzer
The Multi-gas Process Analyzer System is designed to monitor the
gas processes in
single zone batch furnaces for composition with optional temperature
and pressure measurements. The system includes electrically powered
equipment to sample toxic, flammable, possibly explosive gases and
uses high-pressure gas cylinders for calibration.
The system is housed within a NEMA 4 electrical enclosure that is
permanently mounted near the process. The heart of the system is
ARI’s Laser Gas Analyzer (LGA), which is a self-contained gas
sampler/analyzer that uses the principles of Raman spectroscopy to
simultaneously identify and quantify eight gaseous compounds. The
system connects the analyzer to four gas-sampling ports via a unique
valve manifold. Sample scheduling, which is user configurable, is
generally set to continuously cycle through the four ports, one
after another. Sample time at each port is typically 10 to 15
seconds.
The system includes ARI’s multi-port-purge system that uses
an auxiliary pump to simultaneously pre-purge one
or more sample lines while simultaneously analyzing gas in a
specified line. This shortens the time between port-gas measurements
by keeping the sample lines filled with fresh sample gas. The system
also includes ARI’s nitrogen back flush system. Should any of the
four sampling lines become restricted or plugged, pressurized
nitrogen can be forced backwards down the line to clean it.
