Plant operation with modern technology at the Mannersdorf plant

The new SCR process – “semi-dust raw gas circuit” – for NO_x separation was successfully implemented by Scheuch for Lafarge Perlmooser GmbH in Mannersdorf/Austria.

For the past 40 years the company Scheuch GmbH of Aurolzmünster/Austria has been successfully committed to the development and production of dedusting plants and devices for the cement industry. The range of applications extends from the basic pulse filter programme, with its many different varieties ranging from classic dedusting to process gas and hot gas filtration. With EMC filter technology in particular, the past decade has been highlighted by new standards for oven, clinker cooler, mill and chlorine bypass dedusting with respect to bag length, pressure loss, cleaning pressure and bag...
