Switzerland: Thorwesten Vent has completed a turnkey contract for the design and assembly of a large capacity silo for the storage of pulverised lignite in Switzerland. In close cooperation with its sister company, Silobau Thorwesten, the engineering teams of both companies designed a 2300m3 silo that is 55m high and 9m in diameter.
Besides the silo cell, which is equipped with a maintenance-friendly flat roof, Thorwesten delivered all of the safety equipment for required conformation to regulations. The company used its newly-developed self-reclosing explosion venting devices based on a carbon-fibre lid and an emergency inerting system in combination with an intelligent analysis and monitoring system. Additional components, including instrumentation and an in-feed line, completed the order.
