As a result, the demand for building materials has skyrocketed – and to keep supply levels up, cement plants had to import large quantities of clinker. But always a step ahead, Star Cement, one of the leading cement manufacturers in the Middle East, decided to build its own clinker plant. The UAE has strict requirements on fugitive dust emissions, so Star Cement asked the Air Pollution Control unit of FLSmidth to take part in the bidding process for the fabric filter system.

of the filter bags. In addition, the baghouse is equipped with FLSmidth’s SmartPulse™ Controller, which operates the compressed air cleaning system. The controller has an automatic diagnostic feature that analyses pulse duration, time interval and pulse pressure in relation to baghouse differential pressure. It automatically adjusts the parameters to minimise the use of compressed air, ensuring the most efficient operation and maximising the life of the filter bags. FLSmidth was asked to factor the possibility for an increase in clinker production into the filter design. If Star Cement...
