Gas sampling probe H
The gas sampling probe H is used to sample the sample gas from the process.
The following illustration shows the gas sampling probe H:
The main components of the gas sampling probe H are:
No. Component Function
1
Gas tube Transports the sample gas through
the probe to the gas outlet.
2
Connection for air cannon Compressed-air blast from air cannon
breaks up material deposits between
the probe and the wall tube.
3
Wall tube Pipe stub on rotary kiln.
4
Compressed air connec-
tion Allows periodical cleaning of the filter
with compressed air.
5
Compressed-air cylinder Drives the plunger movement.
6
Gas outlet Passes the sample gas to the down-
line sample gas analysis system.
7
Bellows Flexible sealing component between
the outer fixed part of the probe and
the moving plunger part.
8
Cooling water connections Cooling water supply for probe cool-
ing.
9
Mounting flange For fastening the gas sampling probe
to the retractor.
10
Pipe sealing device Spring-mounted sealing of the wall
tube.
11
Filter Initial filtering of the sample gas for
dust removal.
12
Plunger Removes incrustations on the intake
opening.
13
Sample gas intake open-
ing Sucks in the sample gas in the rotary
kiln.
Probe H is used when stubborn incrustations can be expected to build up on the
probe due to the properties of the process and sampling conditions.
