ProKiln GAC400 PROBE GAS SAMPLING SYSTEM | OI/GAC400-EN REV. A

Mode of functioning and operation

Modes of functioning
The following process takes place in order to sample gas during
cement production:
1. General power and UPS power is turned on.
2. Water panel and water cooling of the probe turned on.
3. Electrical heating for probe and sample hose is turned on.
4. Compressed-air (oil and water free) is turned on.
5. All unit and maintenance alarms need to be cleared before
system can enter operation.
6. The system must initially be started in manual mode.
7. The probe is inserted into the rotary kiln.
8. The system is then able to get switched into automatic
mode.
9. The probe gas sampling system will run the sequence of gas
sampling and probe cleaning based on set intervals.
10. The probe gas sampling system will run the sequence of
moving the probe in and out of the process based on set
intervals.
11. The system is switched to manual mode in case of specific
malfunctions or by operator decision.
12. The probe is retracted from the rotary kiln and the flange
shutter is closed.
Modes of operation
The following operating modes are possible:
Mode Description
Automatic mode Allows continuous operation of the system for gas
sampling. Probe cleaning steps and movement of the
probe in and out of the process take place after set
intervals (these can be defined using the controller).
Manual mode Allows operation of the system in manual mode, required
for maintenance, for example. Probe cleaning steps and
movements are controlled only manually by the operator.
