In addition to the testing and analysis provided for RDF & SRF fuels, MSSL offers a similar service for Biomass fuels. This mainly covers testing of Grade 2 & 3 recycled wood as designated by WRAP.
All solid type fuels are subjected to similar sample preparation methods and to the same testing standards as per BS EN 15359: 2011 – ‘Solid recovered fuels.
Details of those tests can be found here.
To provide a power plant with information regarding how the fuel will behave on combustion, Marchwood also offers Ash Fusion & Major Component Analysis including: -
Ash Fusion – Based on BS EN/14775
