Next generation of ceramic hot gas filter with safety fuses integrated in venturi ejectors

The next generation of ceramic hot gas filter system of Pall Corporation with advanced venturi ejector blowback system, longer filter candles and safety fuses integrated in the venturi ejector is presented. The cleaning performance of the advanced venturi ejector blowback system has been investigated using filter candles of 1.5 m length with additionally installed safety fuses and with 2 m long filter candles with and without safety fuses. Measurements of the pressure profiles in the filter elements have been performed for a group of 48 filter elements. The results of these measurements are reported and discussed. The results are compared to reference measurements using the previous standard venturi ejector blowback system with 1.5 m long filter elements.
