In the future pellet market, different fuel qualities like agricultural biomass (e.g. miscanthus, straw) but also different wooden biofuels (e.g. short rotation coppice, wood thinning and waste wood) will be introduced. For the application in small scale combustion systems one major issue is the slag formation tendency of the respective fuel. At the moment a majority of the combustion systems allow the use of DIN+ or ÖNORM pellets exclusively, without losing the warranty of the...
