A continuous-feed rotary reactor system, for pyrolysis and torrefaction, said reactor comprising: an auger-based hopper system, to resolve bridging of waste during feeding, said hopper system comprising an input hopper (H1, H2), being a two-step hopper (H1, H2), for receiving input feed; a first combinatorial airlock valve system (AV1, AV2) forming an airlock feeding system, to bridge transfer of feed, a reactor (R), containing a carbon removal mechanism (CRM) with a second combinatorial airlock valve system (AV3, AV4), said carbon removal mechanism comprising at least a carbon removal screw configured to receive said carbon char, to process said carbon char, and to output biochar, alternative charcoal, feedstock for bitumen modifier, said carbon removal mechanism (CRM) comprising an auger screw mechanism, and an airtight collection mechanism, which comprises the second combinatorial airlock valve system (AV3, AV4), to manipulate residence of time of said carbon char in said reactor.

Various implementations include a combustor system including an inner wall, a fuel grate, an ash grinder, an igniter, and a fan. The inner wall defines a combustion chamber and has a longitudinal axis and first and second ends. The inner wall defines primary and secondary air inlets. The primary air inlets are defined closer than the secondary air inlets to the first end. The fuel grate is disposed within the combustion chamber between the primary and secondary air inlets and is configured to support fuel disposed within the combustion chamber. The ash grinder is disposed between the fuel grate and the secondary air inlets and is rotatable about the longitudinal axis relative to the fuel grate. The igniter provides energy to the combustion chamber. The fan is configured to cause air to flow from the primary and secondary air inlets through the second end of the combustion chamber.

The present invention discloses an industrial solid waste incinerator and flue gas treatment apparatus, comprising a water-cooled feed hopper, a water-cooled grate and a chamber which are connected in sequence. A front arch, a rear arch and side walls which are formed of membrane water-cooled walls, are provided between the water-cooled grate and the chamber, and a dechlorination tower is arranged behind the chamber. Two sets of rear secondary air pipes, which comprise an upper set of rear secondary air pipes and a lower set of rear secondary air pipes, are arranged on the rear arch, and a dry desulfurization device is arranged between the two sets of rear secondary air pipes, so that the reaction medium and the flue gas are sufficiently disturbed and mixed, and stroke is extended.
