One can remove this paradigm by inverting the causality chain: the gasification process is not the result but the origin of less oxygen consumption (compared to combustion). A new construction principle for gasifiers derives from this, and a gasifier built accordingly can test whether removing the traditional paradigm makes sense. The first results from a new type of gasifier that operates with abundant primary air are shown in this paper. The gasifier has a very high power density (10 kW/l) and can process waste biomasses unsuited for traditional gasifiers.展开更多

The setup uses only the thermal solar energy provided by a system of reflecting mirrors (Linear Mirror II) to heat a selected agro-waste biomass, such as wheat straw. At the end of the pyrolysis process, solar carbon with a high energy density (around 24 - 28 MJ/kg) is produced from a biomass with an energy density of 16.9 MJ/kg. The perspectives for a future industrial application of this setup are also discussed.展开更多
