24 CEMENT AMERICAS • Fall 2017 • www.cementamericas.com Advertisers Index PRODUCTS Beumer Group launched an easy-opening stretch film hood that can optimize unpacking operations and elimi- nate the need for cutting tools. The product allows retail store and logistic center employees to quickly and easily remove the film when unpacking or repacking goods. Working with a well-known film supplier, Beumer devel- oped technology that allows opening of the stretch film Beumer Introduces New Stretch Film Hood Construction Inspection Repair www.mariettasilos.com ( 740 ) 373-2822 Silo/Bin Cleaning Roof Coating Vacuum Truck Service Air Pad Maintenance www.usasilos.com ( 740 ) 749-3329 ENOTEC's CEMTEC kiln inlet mea- surement is a robust measuring system that is well suited to cement plants. It allows O2, CO, NO and SO2 parameters to be continuously mea- sured in the kiln inlet chamber. In conjunction with additional measure- ments, it serves to further optimise the production of clinker. The CEMTEC system consists of a probe, compressed air tank, re-cool- er for cooling water, coolant control cabinet, local control box and an analyzer cabinet with built-in PLC. As the probe is inserted, it rotates 90 degrees and the plunger is activated to remove deposits in the tube. Inserted in the process, the probe tube is cooled by a water/glycol cool- ant and is cooled by an air/water re-cooler. A three-way valve provides a constant coolant return tempera- ture of 85 C. In order to prevent the probe from caking stuck in the kiln inlet, the probe rotates 90 degrees in adjustable intervals. Once a day, the probe is retracted and reinserted into the process to ensure that the probe can extract automatically in case an emergency retraction is necessary. The probe extracts the sample gas from the kiln inlet through its internal sintered metal filter. Deposits on the inner fil- ter tube and at the sample gas inlet are removed by regular plunger movement. All functions of the CEMTEC system such as plunger movement, probe rotating, purging and insertion/ retraction can be set exactly via the PLC and adapted to on-site condi- tions. Cyclic impulse cleaning with purge air, which takes seconds, does not interfere with process control as the measured values are blanked out in the control room during purg- ing. The sample gas is extracted through the heated sample gas line for sample gas conditioning and fur- ther to the gas analyzers in the sys- tem cabinet. All of the CEMTEC probe's move- ments are completely pneumatical- ly driven. A sufficiently large com- pressed air buffer tank is used as an energy reserve for an emergency retraction, should the mains voltage or plant air fail. This is controlled by a SIMATIC PLC with backup battery.
