Resumen de: WO2026024667A1
A multi-walled single-chamber pyrolysis system includes an inner cylinder defining an oxygen-starved pyrolysis zone and an overlying primary combustion zone in fluid communication through an opening for biomass gas flow and combustion. A first annulus encircling the inner cylinder forms a secondary combustion zone, sharing inner walls with both the pyrolysis and primary combustion zones for heat transfer. A second annulus around the first annulus defines a primary combustion air flow zone, with thermally coupled walls and channels isolating primary air from the secondary zone while directing it from lower air inlets to the primary combustion zone. A portal at the top of the inner cylinder enables biomass feed and secondary air ingress, with gravity-fed biomass descending through the primary zone into the pyrolysis zone. Exhaust outlets at the base of the first annulus discharge secondary combustion gases.
