Abstract
A tubular reactor useful for converting biomass to char has walls projecting into its interior. The walls are hollow. Cavities in the walls are in fluid connection with the outside of the reactor by way of openings. The reactor may be deployed in a furnace chamber. Hot gases from the furnace chamber may enter the cavities through the openings to heat the walls from within. Biomass may be pyrolized as it passes along the reactor.
Claims32
A reactor for treating biomass, the reactor comprising:
- a furnace chamber;
- a downwardly-sloping tubular reactor vessel extending in the furnace chamber;
- and,
- a plurality of hollow paddles projecting inwardly into a bore of the reactor vessel, the hollow paddles each comprising an internal cavity in fluid communication with the interior of the furnace chamber by way of openings in an external surface of the reactor vessel.
A reactor vessel for use in thermal processing of biomass, the reactor vessel comprising a tubular member having a bore extending longitudinally through the tubular member and a plurality of hollow paddles projecting inwardly into the bore, each of the plurality of hollow paddles comprising an internal cavity in fluid communication with the exterior of the reactor vessel by way of openings in an external surface of the tubular member.
