A coal decomposition gas collecting pipe is arranged in the kiln body and is provided with two parallel spirals for dividing space in the kiln body into a heating gas bin and a coal material decomposition bin. The coal decomposition gas collecting pipe communicates with the coal material decomposition bin through a gas guide hole arranged in the coal material decomposition bin. As the kiln body is internally divided into the a heating gas bin and a coal material decomposition bin isolated from each other, a large amount of hot gas in the heating gas conducts and radiates the heat to pulverized coal in the coal material decomposition bin, and the pulverized coal fully absorbs the heat to be decomposed into gas, coal tar gas and coal with high heat-value.

  • Patent number: 8835704
    Abstract: A biomass pyrolysis process is provided in which biomass feedstock is mixed with a heat carrier. The heat carrier at least partly comprises char. The ratio by weight of biomass to char is in the range 1:1 to 1:20. The process may be carried out by in a screw/auger pyrolysis reactor in which the solid feedstock components are conveyed along the reactor by a first screw. A second screw conveys at least a portion of the solid products of the biomass pyrolysis back to a heat transfer medium input port. Thus, the heat transfer medium includes char from the biomass pyrolysis.

  • Patent number: 8795476
    Abstract: A reactor for converting organic feed is provided. A retort extends through the furnace of the reactor. The retort has a retort auger, an inlet and an outlet. The reactor includes a charcoal delivery assembly having a collection line, delivery line, and a transfer zone. The collection line is adjacent to the outlet of the retort receives charcoal from the retort, and contains a collection auger with a flighted portion extending at least partially therethrough. The delivery line is connected to a downstream portion of the collection line and has a flighted delivery auger extending therethrough. The transfer zone is a space, between a downstream end of the flighted portion of the collection auger and an upstream end of the flighted delivery auger, where charcoal collected and delivered by the collection auger forms a plug, thereby blocking biogas from the retort from entering the delivery line.
