Pyrolyser

A pyrolyser, comprising:

• (i) a pyrolysis chamber defining an interior compartment having an upper portion and a lower portion, wherein the pyrolysis chamber includes a feed inlet, a product outlet, an exhaust gas outlet, and an operational length comprising a linear distance from the feed inlet to the product outlet;
• (ii) a trough housed inside the pyrolysis chamber and located in the lower portion of the interior compartment and extending through the pyrolysis chamber along the operational length of the pyrolysis chamber;
• (iii) a material handling system comprising (a) a screw auger, (b) a paddle auger, or (c) a combination of (a) and (b), the material handling system being located within the trough and configured to convey biomass from the feed inlet towards the product outlet;
• (iv) a primary air source including a plurality of primary air pipes configured to discharge primary air proximately above and across a top portion of the trough;
• (v) a secondary air source including one or more secondary air pipes configured to discharge secondary air into a rear portion of the pyrolysis chamber and into an intermediate portion of the pyrolysis chamber in a z-direction of the pyrolyser that is located above the plurality of primary air pipes in the z-direction;
• and
• (vi) a tertiary air source including one or more tertiary air pipes extending along the upper portion of the pyrolysis chamber from a rear portion of the pyrolysis chamber towards a front portion of the pyrolysis chamber, the one or more tertiary air pipes are located above the one or more secondary air pipes in the z-direction;
• wherein the one or more tertiary air pipes each includes a plurality of tertiary air orifices along a length of each tertiary air pipe.

• (iii) a material handling system comprising a paddle auger located within the trough and configured to convey biomass from the feed inlet towards the product outlet;
• wherein the paddle auger comprises an auger shaft, a plurality of sets of paddles directly or indirectly connected to the auger shaft, and a plurality of flights interconnecting the plurality of paddles;
• (iv) a pair of opposing apron sections having corresponding upwardly facing surfaces that extend from corresponding side walls of the pyrolysis chamber and terminate adjacent or proximate to a top portion of the trough;
• (v) a primary air source including a plurality of primary air pipes configured to discharge primary air proximately above and across a top portion of the trough;
• (vi) a secondary air source including one or more secondary air pipes configured to discharge secondary air into a rear portion of the pyrolysis chamber and into an intermediate portion of the pyrolysis chamber in a z-direction of the pyrolyser that is located above the plurality of primary air pipes in the z-direction;
