A biomass heating system for firing fuel in the form of pellets and/or wood chips is disclosed, comprising: a boiler with a combustion device; a heat exchanger with an inlet and an outlet; wherein the combustion device comprises a combustion chamber with a primary combustion zone and with a secondary combustion zone provided downstream thereof; the combustion device having a rotating grate on which the fuel can be burned; the secondary combustion zone of the combustion chamber being fluidically connected to the inlet of the heat exchanger and the primary combustion zone being laterally enclosed by a plurality of combustion chamber bricks.

The invention provides a thermal cracking system which comprises a reactor, and a feed module or a solid product discharge module. The feed module transports a feed material from the outside environment to the reactor. While being transported, the feed material is heated by the feed module to become molten and fills up the interior of the feed module, thereby preventing air from entering the reactor. The solid product discharge module transports a solid product from the reactor to the outside environment. One end of the solid product discharge module is connected with the reactor. The other end of the solid product discharge module comprises a first opening interfacing with the outside environment. When the solid product is transported to the outside environment, the opening size of the first opening is selected such that the speed at which the solid product is entering the solid product discharge module form the reactor is equal to or greater than that at which the solid product is leaving the solid product discharge module, through the first opening, and into the outside environment. Benefit of the invention includes a higher production efficiency and enhanced safety for a thermal cracking system at industrial scale.

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.

A feed system for a reactor, a reactor assembly comprising such a feed system, and a method of supplying a feed material to a reactor with a feed system are provided. The reactor may be a pyrolysis reactor, such as a fluidised bed pyrolysis reactor. A method of pyrolysing a feed material is also provided. The feed system may comprise a feed conduit extending from an inlet to an outlet, and may have a first section including the inlet and a second section including the outlet. The first section may accommodate an auger. The second section may comprise at least one plug forming zone in which feed material is compressed into a substantially gas-tight plug during operation. There may be a temperature regulator for controlling the temperature in the second section. The temperature regulator may comprise a cooling jacket.

A method for commissioning a biomass heating system for combusting fuel in the form of pellets and/or wood chips, the biomass heating system comprising a boiler with a combustion chamber, a blower and a control device with a memory and a display, the method comprising the following steps: Determining (S2) whether the biomass heating system is initialized for the first time, wherein if the biomass heating system is not initialized for the first time, the method is terminated, and if the biomass heating system is initialized for the first time, the method is continued with the following step: Setting a plurality of heat generation parameters (S5) comprising at least the following parameters: a boiler type parameter defining at least a working range of the blower; a material parameter defining the characteristics of the fuel(s) to be combusted.

A rotating grate for a biomass heating system is disclosed, the grate comprising: at least one rotating grate element; at least one bearing axle, by means of which the rotating grate element is rotatably mounted; at least one cleaning device attached to one of the rotating grate elements, wherein the cleaning device comprises a mass element movable relative to the rotating grate element; wherein the cleaning device is arranged in such a way that, upon rotation of the rotating grate element, an acceleration movement of the mass element is initiated so that the cleaning device exerts a knocking effect on the rotating grate element in order to clean the rotating grate element.

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.

A grilling device includes an auger feeder system, a heating element, a blower and a temperature control system. The temperature control system includes at least a first temperature sensor inside the firepot and a second temperature sensor inside a cooking chamber above the firepot. The heating element can also serve as the first temperature sensor. A method for controlling the temperature of the grill can include receiving temperature feedback information from one or more of the temperature sensors and adjusting power provided to the auger feeder system, heating element, and blower. The temperature control system produces cold smoke resulting from the combustion of lignin in solid wood fuel while minimizing temperatures inside the cooking chamber.

An apparatus for thermal processing of waste having organic and inorganic components comprises at least a treatment station, a cooling station and a treated material-removal station, and at least three crucibles. The treatment station is adapted to thermally treat the organic components and/or inorganic components located in a given one of the crucibles located at the treatment station. The so-treated components in this given crucible are adapted to then be cooled at the cooling station, before the treated components located in the given crucible are removed therefrom at the treated material-removal station. The three crucibles are mounted on a turntable so that the three crucibles are each at one of the stations, before synchronously all moving to each crucible's next station.
