Rwe lignite drying technology

In 2009, a commercial prototype facility commenced operations in the RWE Innovation Centre. This prototype facility can generate up to 110 tonnes of dry lignite per hour, which corresponds to up to 30 % of the entire coal requirement of the block lignite power station with optimised equipment technology (BoA) in Niederaussem

    basic process-technology opera-tion, drying occupies a key posi-tion in lignite upgrading as well. Here, too, an energy-efficient dry-ing method improves the energy balance of the overall process. As a modern method for process-ing and drying lignite, WTA tech-nology can be used and adapted to all of the above processes. It

    RWE Power in Germany has also developed a fluidized-bed drying technology for lignite. The technology concept developed by RWE is called Wirbelschichttrocknung mit interner Abw rmenutzung (WTA) technology (English: Fluidized-bed drying with internal waste heat utilization), which is arguably the most advanced superheated steam drying technique

    Coal-drying technology. RWE researched and developed an efficient lignite drying technology, called WTA™ technology, which dries lignite from more than 65% to 10% moisture. The first commercial-sized WTA drying plant with evaporation heat recovery was commissioned in 2009 at RWE’s Niederau em power plant. Our WTA-related services include:

    In WTA the heat used for drying is largely recovered. The result is much higher efficiencies, about 10% higher than the current state of the art. RWE sees WTA as an essential enabling technology for future dried lignite fired conventional power plants as well as its lignite-fuelled IGCC project, which it has been planning since about mid 2006
