23-Feb-2014 - Torrefaction, a staged roasting process of woody biomass, to create a dense product with a high calorific value and coal like characteristics - but yet renewable - has reached a new milestone, which could accelerate growth of the emerging torrefaction market.
Topell Energy, a leading provider of innovative torrefaction solutions, has successfully provided a 2300 tonnes sample of torrefied pellets from their plant in Duiven, the Netherlands, to test co-firing performance at traditional coal power plants and the results are reported to be excellent (source: www.topellenergy.com, press release, 4 February 2014).
Apart from excellent potential as a coal replacement, torrefied wood offers lower cost and safer transportation vs. traditional wood pellets. In addition, new areas of usage are under development, including designer carbon for use in industrial processes and as feedstock for higher grade syngas generation for CHP plants and ultimately for production of bio-chemicals and bio-fuels.
The Topell torrefaction plant at Duiven is utilising TORBED reactors for the core torrefaction process, offering unique process control and the ability to produce consistent output efficiently. The TORBED reactors and the associated Torftech Technology is exclusively owned and marketed globally by Torftech Energy, a progressive provider of innovative biomass and waste feedstock upgrading and decentralised power plant solutions.
