Technical description The unit allows fast, intermediate and slow pyrolysis of dried organic residues. Biomass particles are fed via a screw feeding unit, which itself can be used for slow pyrolysis. Inside the pyrolysis compartment vapours are transported upwards by an inert gas flow. Formed char particles are collected below the pyrolysis section. Gas samples can directly be taken from the pyrolysis section. Pyrolysis vapours are transported to the condensation section via heat-traced lines either to a fixed bed reactor for vapour upgrading and then or directly to a condensation section consisting of glass condensers operated at different temperatures and an electrostatic precipitator.
Technical information
