SQ250 FLK Gas Sampling System
2. Installation
2.1 General information
In cement production two main installation areas are relevant:
• Kiln inlet
• Precalcination
It is essential that the installation location and the mounting are defined, with respect to the space requirement, between the
machine supplier or user and SIEMENS
Note: In relation to the individual components there are separate operating manuals in which the precise details
of construction, installation, operation and servicing are dealt with comprehensively.
This is especially relevant to the probe installation location (sampling device) and the electrical installation.
2.2 Fitting the probe
2.2.1 Installation in the kiln inlet
The following points should be followed for gas analysis on the kiln inlet:
• Preferentially the probe should be fitted at the side on the kiln inlet chamber.
• It should be positioned slightly oblique to the kiln axis.
• The probe should be fitted to the side opposite to the side of the raw meal feed.
• The probe must protrude at least 30 cm behind the kiln seal (vertical distance).
• The probe must not pass near to the material flow from the preheater tower.
• It should be ensured that no heavy solids can fall down from the preheater onto the probe.
• The probe must have a distance of at least 20 cm from the lining of the rotary kiln. When installing the probe in a new
kiln, pay attention to the lining and kiln expansion in the hot state.
• Appropriate space must be available for installing and removing the probe, for the feeder lines such as coolant hoses,
compressed air line, measuring gas line and cable.
• Access to the probe for installation and service work should also be provided.
2.2.2 Installation in the precalciner
The following points should be followed for gas analysis in the precalciner:
• The probe must be installed in an area as free of dust as possible. This position is normally after a cyclone and under a
diffusion box.
• This probe must protrude at least 1/3, but at the most up to the middle of the gas line.
• The installation location should also be so planned such that the effects of heat on components such as the valve
combination and the dedusting filter are not too high.
• With this installation location a closing flap should be fitted if possible to the installation pipe by the customer (possibly
automatic or manual).
• Appropriate space must be available for installing and removing the probe, for the feeder lines such as coolant hoses,
compressed air line, measuring gas line and cable.
• Access to the probe for installation and service work should also be provided.
