The gasification is based on entrained-flow principle, which produces a clean and stable gas quality. The technology is also suitable for various feedstocks, even fine fraction residues such as sawdust and wood fibre.Meva Energys ision is to produce and deliver gasification units that use local biomass residues to generate energy at site. Hence, without need of costly and complex upgrading, unnecessary transport and parasitic losses. The gas needs to fulfil the function of itsFigure 2.
