ProKiln GAC400
PROBE GAS SAMPLING SYSTEM | OI/GAC400-EN REV. A
5
Intended use
The probe gas sampling system is used to continuously monitor
process gas in cement production:
• at primary firing at the kiln inlet of the rotary kiln
• at secondary firing at the process gas outlet of the
calciner
Analysis of the sample gas is performed by means of a suitable
continuous gas analyser system, for example the AO2000-
System, AO2000 Series or EL3000 Series from ABB AG, or any
existing well-functioning gas analysis system or other third-
party supplier's solution.
The continuous gas analyser system technology can be based on
cold/dry or hot/wet.
Improper use
The probe gas sampling system may not be used:
• to sample mixtures of gas/air or gas/oxygen that are
capable of ignition during normal service.
• to sample flammable gas which may form an explosive
mixture in combination with air or oxygen.
• in a potentially explosive atmosphere or in explosion-
hazard areas.
• to sample extremely toxic or extremely corrosive gases.
• in process temperatures above 1400 °C (2552 °F).
• in process dust loads higher than 2000 g/m³ (2 oz/in³).
• in condensing process conditions.
Further actions that may cause damage to the ProKiln system or
lead to hazardous situations:
• Forcing the ProKiln probe into the kiln while the flange
into the kiln is completely blocked.
• Forcing the use of the air blasters when the probe is not
in a safe position inside the kiln.
The restrictions of the gas analysis system have to be checked
separately.
Basic safety rules
Target group for these rules
These rules are intended for all persons handling the probe gas
sampling system in any situation.
Purpose of these rules
The purpose of these rules is to ensure that all persons handling
the probe gas sampling system are thoroughly informed about
risks and safety measures and that they observe the safety
instructions in the operating instructions and on the system.
Failing to observe these rules can lead to a risk of damage to
property, injuries or even death.
Handling the operating instructions
Observe the following rules:
• Completely read through the Safety section and the sections
pertaining to your work. You must have understood these
sections.
• Always keep the operating instructions handy nearby the
probe gas sampling system for reference.
• Pass on the operating instructions if the probe gas sampling
system is re-sold.
Handling the probe gas sampling system
Observe the following rules:
• Only persons fulfilling the requirements specified in these
operating instructions may handle the probe gas sampling
system.
• The probe gas sampling system may only be used for the
intended purpose. Never use the probe gas sampling system
for any other purposes, even if they appear reasonable.
• Take all safety measures specified in these operating
instructions and on the system. Specifically, use the
prescribed personal safety equipment.
• Only work in the designated work areas.
• Do not make any modifications to the probe gas sampling
system, e.g. by removing parts or attaching non-approved
parts. Specifically, do not change or disable any protective
installations.
• Use only original spare parts when replacing defective
components.
• The probe gas sampling system may only be operated if
maintenance work is performed regularly and expertly.
