The present invention relates to an apparatus, which can be part of a pre-treatment system in a plant for the production of fuels, e. g. bio-ethanol, derived from plant biomass, e. g. first generation crops, such as grain, sugarcane and corn or second generation crops such as lignocellulosic biomass. The invention relates to an apparatus for processing, such as fluffing and mixing, at least two media, such as a solid, e. g. biomass, and a fluid, e. g. steam, so as to rendering the first medium susceptible to efficient receiving of energy and/or mass which is provided by localized release of the second medium. Although the description of the present invention focuses on biomass, it is envisaged that the invention is generally applicable to control the mixing of at least two media by crossing their stream of while dispersing at least one of them.

An apparatus and method for controlled ventilation and aeration of liquid medium includes a dome supported by a flotation device, a lower housing supported by the flotation device, the lower housing connected to the dome, wherein a sealed space is defined under the dome and above the flotation liquid, one or more orifices, the orifices configured in the dome, and an aeration apparatus positioned within the sealed space and partially submerged in the flotation liquid, wherein the aeration apparatus includes one or more parallel shafts, at least one first disc positioned axially on one of the shafts, at least one second disc positioned axially on another of the shafts, wherein the second disc is interleaved relative to the first disc, and wherein a surface of the first disc rotates in a direction opposite a surface of the second disc relative to each other resulting in a mixing area therebetween.

Present disclosure a multi-component supercritical thermal fluid generation system and method with segmented air supply. The outlet of a water tank is communicated with the preheated water inlet of a multi-component supercritical thermal fluid generator body, the preheated water outlet of the multi-component supercritical thermal fluid generator body is communicated with the cold fluid inlet of a heat exchanger, the product outlet at the upper part of the multi-component supercritical thermal fluid generator body is communicated with the thermal fluid inlet of the heat exchanger, and the slag outlet at the lower part of the multi-component supercritical thermal fluid generator body is communicated with the inlet of a slag discharge lock hopper. Through the reasonable coupling design of the supercritical water gasification heat absorption zone and the oxidation reaction heat release zone in the multi-component thermal fluid generator, the self-heating of the multi-component supercritical thermal fluid generation system is realized.
