In 2009, Scheuch transferred the advantages of its patented Energy Minimizing Concept (EMC) technology to applications using 10 metre filter bags and verify these advantages in actual practice.
This concept was developed especially for long filter bags, for air-to-cloth ratios considerably greater than 1.0 m3/(m2·min) and dust loads up to 800 g/Am3. The main advantage associated with longer filter bag lengths is primarily the clearly lower investment costs, which are the result of the compact design and a weight reduction of up to 30 percent compared EMC 6 metre filter bags. In addition, applications using 10 metre filter bags require only half of the installation space compared to those using the 6 metre filter variant. In filters equipped with 10 metre bags, the proportions of length to width to height are also more flow-optimized and assure a better distribution of dust across the overall length in comparison to filters using shorter bags. The use of EMC 10 metre is already of interest starting at volume flows of 500000 Am3/h and can cover a range of up to 3000000 Am3/h. Especially when converting electrostatic precipitators to bag filtration systems, the existing casing volume can thus be used to optimal advantage. The possibility of installing a significantly larger filter surface area makes it possible to create reserves for future increases in performance (larger volume flows) in a cost-effective way. The same is true for existing filtration systems with bag lengths of 6 or 8 metres, especially when space is limited and the overall length cannot be extended.
