    摘要: A system for producing superior quality synthesis gas (“syngas”) consisting of a series of chambers in which the gasification stages of reaction, homogenization and activation occur. The first stage reaction stage agitates and combines the reactants, consisting primarily of organic matter, oxidizer and steam, to initiate gasification of the organic and volatile fraction and to transport the inorganic residue to continuous removal. In the homogenization chamber, turbulence is induced by injecting gaseous species. The gas mixture emerging from the homogenization chamber is accelerated via a third stage communicating duct and is introduced tangentially into the fourth stage activation chamber inducing a cyclonic motion wherein a high intensity radiant heat source is introduced along the central axis of the gas vortex. The syngas and remaining particulate materials are constrained to exit the activation stage through discrete portals which are oriented to further separate the syngas from the remaining entrained particulates.

    摘要: A gasification reactor (1) and a process for the production of syngas by gasification of a carbonaceous feed. The reactor comprises a gasifier unit with a discharge channel (4) for discharging a stream of slag-loaded hot syngas and a quencher (5) for supplying a flow of quench gas into the discharge channel (4). At least one blaster (10) is arranged comprising at least one blast nozzle (12), such as a blast lance, in line with the flow direction of the quench gas. The blaster (10) can be connected to a source of pressurized gas, such as syngas, nitrogen, carbon dioxide, steam or the like. The blaster can be actuated periodically to blast away slag deposits.

    摘要: A dry feed two stage gasification system and process is disclosed for gasifying feedstock such as carbonaceous materials with improved energy efficiency, along with reductions in feedstock consumption and carbon dioxide emissions. The feedstock is first dried and pretreated with the hot syngas in the upper section of the gasifier to generate a dry char that is low in volatile-matter content. This dry char is sent to the first stage of a two stage gasifier where it reacts with oxygen in the presence of steam to produce a hot syngas stream.
