4. Examination of our existing CVF-construction Dynamic flow simulation of air velocity in the cyclone and vortex finder, and predicted pressure outside and inside the vortex finder 4

5. Innovation in Refractory Solutions Issues for refractory producers: Solving the problem Improving processes Understanding of the application Identification of constraints Essential dialog about experience; successes and failures 5 workabilitypropertiesperformancelife-time

6. Essential interaction: Refractory producer End user Installation company 6 Effective production Short shut down Low costs Good workablity Health and Safety Flexibility Low costs Material properties Raw materials Effective production

7. Example of product development based on enquiries from customers HASLE PU55A; A low-cement, pumpable castable, with excellent abrasion-, alkali- and slag-resistance Request; Easy transport of castable from mixer to mould without reducing the quality and performance of the castable Solution; An easy mixable low cement castable that can be pumped vertically and horisontally through hose or pipes without segregating 7

13. Recipes and raw materials Installation methods and design Analyses of vapour, slag and build-up Post mortem analyses Optimized refractory solution 13

14. Post mortem analyses Close collaboration with Aachen University, Institute of Mineral Engineering, Department of Ceramics and refractory Materials Understanding the mineral and structural changes that occurs during the lifetime of a refractory lining, enables us to target and enhance the following product optimization 14

15. Future R&D at HASLE New castables: Pumpable castables and shotcreting High quality low cement gunning castables Constantly improving our refractory solutions to withstand the challenges caused by: A growing diversity of alternative fuels Higher operation temperatures Increased production efficiency and demand for reduced energy costs Shorter shut-down periods 15

16. Summary HASLE has its own laboratory to carry out quality control, analyses and product development HASLEs technical department can help you on design and construction HASLE continuosly analyse and improve existing solutions Constructive dialog between refractory producer and users is essential for successful innovation HASLE has developed a pumpable castable requested by customers Knowledge comes from a wide range of sources Analysing degradated material enables us to target optimization In the future HASLE will focus even stronger on solving the refractory challenges caused by alternative fuels PLEASE JOIN THE DIALOGUE IN OUR FUTURE R&D 16
