It’s that process that allows us to insert the waste or the biomass in a reaction chamber without oxygen (30% compared to outside atmosphere) at a high temperature (minimum 600, max 1100 Celsius degrees) and to transform that solid matter into a gas so to avoid the flame stage; the result is the production of a Syngas (which is, precisely a synthesis gas) that, when it comes from a woodsy biomass gasification, it can be used to operate gas powered endothermic engines cycle eight. Otherwise, when Syngas comes from the gasification of solid urban waste, because of the great variability of the same waste, it can be used exclusively for its very high temperature in a heating coil that is parallel to another in which hot water circulates or, as an alternative, a thermal fluid meant to operate a turbine. In both cases the final result is the production of a very limited environmental impact energy (70% less) compared to direct combustion used for more traditional and obsolete burners, thanks to the absence of flame.
