Waste disposal industry

A large number of waste materials can be used as a raw material for energy production. These alternative fuels (RDF (Refuse Derived Fuel) & SSW (Solid Shredded Waste) are coming more into focus. Drying systems help to process this raw material. Be it increasing the caloric value for power generation or to improve the controllability of the combustion plants, we at STELA always offer the perfect solution with our individually adapted belt dryers. Because we also use the low-caloric waste heat, the economic operation of the drying system is also ensured.

Belt dryer type BT with air circulation

If products require drying to a very low final moisture content, the problem usually arises with traditional drying systems that the air has a lower saturation point towards the end of the drying phase. At the same time, there is still a large amount of heat that could be used in the exhaust air, which is released into the surrounding area.
