Guided radar sensor VEGAFLEX steams ahead to ensure efficient process heat supply
At the DSM site in Visp, Switzerland, they specialise in food additives, and 30 % of the energy needed for their processes is made by generating steam. The energy production process ranges from the combustion of waste materials, as well as the typical stages of steam generation, right through to complex flue gas cleaning systems. The combustion chamber, which supplies the energy for the steam boiler, extends over three building floors at DSM. At a temperature of 190 °C, the boiler generates saturated steam at 13 bar pressure, increasing the specific volume of the water by 15 % compared to its specific volume at atmospheric pressure. The level values in the boiler, which supplies the steam distribution system, requires perfect balancing. It needs to be meticulously controlled according to preset, fixed safety parameters.
Combination flanges are generally used in confined spaces and difficult installation situations, but are also ideal for safety-critical applications.
Measurement technology for use in steam boilers
Christoph Fux is quite pleased with the new solution, as it contrasts strongly with his recent negative experience with capacitive based measurement at the same location. The steam generation system has been running smoothly and safely ever since.
