A system for inerting a biomass feed assembly the system including a combustion chamber operably connected to the biomass feed assembly to receive a biofuel, the combustion chamber operable to combust the biofuel and generate a flue gas therefrom and a conduit operably coupled to at least one of the combustion chamber and an inert gas source, and the biomass feed assembly, the conduit operable to carry a gas to the biomass feed assembly. The gas sweeps dust generated in at least the gravity chute assembly toward the combustion chamber and the gas maintains an oxygen partial pressure or concentration in the at least a portion of the biomass feed assembly below a selected threshold sufficient to suppress ignition.

The invention comprises: a) first comburent supplying means (18) connected to the lower part of the oxidation chamber, for introducing pressurized oxygenated gas in the oxidation chamber at a speed that comprises a tangential component; b) a particle recirculation system, which comprises: a particle separator (24) on the upper part of the oxidation chamber for trapping hot particles of ash and unburned material, and a transportation system (25) for transferring trapped particles from the particle separator (24) to the base of the oxidation chamber; and c) a gas recirculation system comprising: a sucker (26) for suctioning combustion gases from the upper part of the oxidation chamber, and pipes (27) for transferring the suctioned gases to the base of the oxidation chamber. It provides an optimized thermal transfer that reduces the emission of pollutants in waste recovery.

An apparatus and a method is provided for continuously drying bulk goods, in particular wood fibers and/or wood chips, in a dryer, wherein the drying vapors are led to a dryer circuit, in which the drying vapors are indirectly heated via a heat-exchanger and are conducted to the dryer again.

Plastic-powered power generator. In an embodiment, the plastic-powered power generator comprises a primary reactor with an air-fuel distribution assembly configured to supply fluidized polymer, air, and oxidizer to a primary reactor chamber, and an ignition system configured to ignite a mixture of the fluidized polymer, air, and oxidizer. The primary reactor chamber extends into a secondary reactor, to, when ignited, heat air flowing through the secondary reactor from a blower to a heat exchanger. The heated air flow may convert fluid, in a coil within the heat exchanger, into steam, which can drive a turbine to generate electrical power.

A flare system including a flare stack and a modular flare unit connected in parallel with the flare stack. The modular flare unit includes a frame, at least two energy conversion modules detachably supported by the frame, a fuel manifold, an air manifold, an exhaust manifold, and an electric generator. Each energy conversion module includes a combustion chamber configured to receive a flow of residue gas through the fuel inlet for combustion in the chamber at (or close to) atmospheric pressure, and a Stirling engine configured to convert heat from the combustion chamber into mechanical energy. The electric generator is connected to generate electric power from the mechanical energy.

Existing approaches to refuse handling are all based on historical approaches which rely on a network of refuse collection vehicles collecting waste from individual households and delivering this to a centralised landfill or MBI location. This is highly undesirable and wasteful. An alternative process is disclosed, relying on the thermal treatment of waste and like products produced or brought in to the residential property and processed within the domestic curtilage to produce fuel or other forms of energy. Thus, domestic waste will be thermally treated at the home instead of being collected by local authorities and disposed of. The waste input put material will be loaded into a domestically engineered thermal conversion unit either directly or after a pre-process such as shredding. The feedstock will be converted into fuels by a thermal treatment, such as pyrolysis. The resultant output of oil and gas can either be stored or fed into a boiler unit to be used as a fuel to produce hot water, or used to run an electricity generating unit to power the dwelling in question or for supply to a feed-in tariff. Thus, a domestic dwelling includes a thermal treatment unit for processing waste produced in the dwelling, an output of the thermal treatment unit being combusted for producing an energy output for the dwelling. A suitable pyrolysis chamber is disclosed.
