No more coal dust accumulation within the DEKOMTE Expansion Joint Solution! Location NSW, Australia Industry Power Generation Client Coal Briquet Production Challenge In a coal dryer system, flexible joints are used on inlets and outlets of the gas recirculating fans. These joints are primarily to isolate vibration to the structure and some minor thermal expansion. In this case study, the coal dryer system runs at 160 deg C°, at approx. 10kPa, with the fans conveying a hot inert gas with entrained coal dust. If the coal dusts settle or accumulate in the expansion joint cavity and bolster space, this will spontaneously combust when the inert coal dryer gets turned off and the dryer returns to normal ambient conditions, i.e. normal 21% O 2 air. Hence it is of utmost importance
