KILN SHELL TEMPERATURE
The early detection of ‘hot’ or ‘cold’ spots is vital to avoid costly maintenance or an unplanned shutdown. Continuous monitoring of the kiln shell along its length day and night will provide the earliest possible indication of potential problem spots.
ROTARY KILN PRODUCT TEMPERATURE
Sighting tubes of different lengths are installed in various kiln positions - the radiation thermometer accurately measures the temperature at the end of the tube once very kiln rotation. Depending on the thermometer location either the solids (for product quality) or the gases (for kiln efficiency) within the kiln can be measured.
ROTARY KILN BURNING ZONE TEMPERATURE
Measurement of the temperature in the kiln burning zone is vital for maintaining both product quality and kiln efficiency. A 2-colour (ratio) thermometer is used to overcome the inherent problems of dust etc. which obscure the thermometer sight path. This system can be applied equally to both wet and dry processes.
CEMENT CLINKER TEMPERATURE MEASUREMENT
To safeguard against either fire or belt burn out the clinker in the bucket elevator must be sufficiently cooled prior to reaching the rubber conveyor. A thermometer used in a closed control system monitors the temperature of the clinker before it reaches the conveyor. This system sets the cooling levels and improves operating efficiency.
