摘要:
A device for producing fuel gas from materials of organic and/or inorganic origin, comprising filling chamber connected to at least one supply auger conveyor for supplying material from the filling chamber into a reactor comprising at least two heated gasification augers. The invention consists in the fact that each horizontal row of gasification augers is formed by a gasification body, the casing of which has a closed oval cross-section formed by an upper base, a lower base, and convex side walls each with circular arc profiles, wherein each gasifying body contains at least two gasification augers arranged side by side and mutually partially separated by longitudinal partitions that form half-grooves for gasifying augers. The device is provided with at least one electrical heater. The filling chamber is hermetically sealed.
摘要:
A direct carbonaceous material to power generation system integrates one or more solid oxide fuel cells (SOFC) into a fluidized bed gasifier. The fuel cell anode is in direct contact with bed material so that the H2 and CO generated in the bed are oxidized to H2O and CO2 to create a push-pull or source-sink reaction environment. The SOFC is exothermic and supplies heat within a reaction chamber of the gasifier where the fluidized bed conducts an endothermic reaction. The products from the anode are the reactants for the reformer and vice versa. A lower bed in the reaction chamber may comprise engineered multi-function material which may incorporate one or more catalysts and reactant adsorbent sites to facilitate excellent heat and mass transfer and fluidization dynamics in fluidized beds. The catalyst is capable of cracking tars and reforming hydrocarbons.

摘要:
A system and process capable of promoting the energy content of a syngas produced from a biomass material. The system and process entail compacting a loose biomass material and simultaneously introducing the compacted biomass material into an entrance of a reactor tube, and then heating the compacted biomass material within the tube to a temperature at which organic molecules within the biomass material break down to form ash and a fuel gas mixture. The fuel gas mixture is withdrawn from the tube and the ash is removed from the tube through an exit thereof. The entrance and exit of the tube, the compaction step, and the removal step cooperate to inhibit ingress of air into the tube by forming a plug of the biomass material at the entrance of the tube and a plug of ash at the exit of the tube.
摘要:
A system and method capable of efficient production of synthesis gas from biomass materials in a manner which can be scaled to relatively large throughput capacities. the system is operable to compact a loose biomass material and simultaneously introduce the compacted biomass material into entrances of internal passages of multiple parallel reactors, heat the compacted biomass material within the reactors to a temperature at which organic molecules within the compacted biomass material break down to form ash and gases comprising carbon monoxide and hydrogen gases, inhibit combustion of the compacted biomass material when heated within the internal passages of the reactors, conduct the carbon monoxide and hydrogen gases through the reactors in a direction opposite the movement of the compacted biomass through the reactors, and remove the ash from the reactor.
摘要:
A partition divides an enclosure into an upper space and a lower space, the partition having a hole which provides essentially the only passage for gas to flow from the lower space to the upper space. A reactor tube having open ends is supported by the partition over the hole, and a grate spaced below the hole. A primary air inlet arrangement feeds air into the lower space for gasification of solid fuel on the grate, and a secondary air inlet directs a jet of air toward the inlet end of combustion tube communicating with the upper space and having an open exhaust end outside the enclosure. Product gas formed by gasification of solid fuel on the grate and passing through the reactor tube into the upper space will be drawn into the combustion tube to create a sub-atmospheric pressure in the upper space.

High-temperature apparatus (10) for converting an starting material (M) to a synthesis gas (G) and comprising a feeding device (30) and a rotationally symmetrical furnace pipe (20) having a rotation axis (R). The feeding device (30) conducts the starting material (M) into an inner chamber (I) of the furnace pipe (20), and conveying elements (22) are arranged in the inner chamber (I) of the furnace pipe (20) in order to convey the starting material (M) in the direction of an exit side (A) of the furnace pipe (20). The apparatus (10) comprises an elongate resistance heating (23), which protrudes into the interior (I) of the furnace pipe (20) and which comprises at least one hot zone (H1) and a less hot zone (H2), wherein the hot zone (H1) follows the less hot zone (H2) as viewed from the entry zone (E), and wherein the resistance heating (23) is configured such that a temperature that is above 1200° C., is achievable in the inner chamber (I) of the furnace pipe (20).

摘要:
In the case of a device for gasification of carbonaceous fuels, having a discharge for slags into a slag bath, a solution is supposed to be created with which the gasifier discharge opening is reliably kept at a temperature that guarantees that the slag will flow out. This is achieved in that the gasifier discharge opening (6) is equipped with a ceramic drip edge (7) that can be electrically heated.
