CEMTEC - Self-cleaning probe for cement plant kiln inlets
CEMTEC provides many years of operation in cement kilns or in applications with high temperatures and/or high dust loads. The patented CEMTEC consists of a watercooled probe, which is mounted on a pneumatic propulsion device and travels in and out of the combustion process.
In addition to the InSitu sensors for the instantaneous O2 and COe analysis, a heated gas sampling tube is located in the measuring chamber. The extractive analyzer is supplied with sample gas through this tube for measurement of e.g. SO2, NOx or CO.
Due to the mechanical cleaning, the continuous extraction and analysis of process gas is possible over a long period of time. The dust filter with its impact plate at the tip is coaxially mounted within the cooling protection tube and moves in programmable intervals out of the tip of the cooling protection tube to remove any dust deposits.
The patented CEMTEC swivel drive prevents deformation of the probe tube from falling debris and the cementing of the gas sampling probe by continuously turning within the combustion chamber.
