A thermal receiver and the reactor tubes are aligned to 1) absorb and re-emit radiant energy, 2) highly reflect radiant energy, and 3) any combination of these, to maintain an operational temperature of the enclosed ultra-high heat flux chemical reactor. Particles of biomass are gasified in the presence of a steam carrier gas and methane in a simultaneous steam reformation and steam biomass gasification reaction to produce reaction products that include hydrogen and carbon monoxide gas using the ultra-high heat flux thermal energy radiated from the inner wall and then into the multiple reactor tubes. The multiple reactor tubes and cavity walls of the receiver transfer energy primarily by radiation absorption and re-radiation, rather than by convection or conduction, to the reactants in the chemical reaction to drive the endothermic chemical reaction flowing in the reactor tubes.

va Solid feed systems for elevated pressure processes, gasification systems and related methods By www.freepatentsonline.com Published On :: Tue, 05 May 2015 08:00:00 EDT A solid feed system may comprise a supersonic nozzle, an isolated injection section having a port for injection of solid feedstock positioned downstream from the supersonic nozzle, and a supersonic diffuser positioned downstream from the isolated injection section. Additionally, a gasification system may comprise such a solid feed system and a reaction chamber downstream thereof. Furthermore, a method of reacting a solid feedstock under pressure may include directing a fluid flow through a supersonic nozzle to provide a supersonic flow stream, and directing the supersonic flow stream through an isolated injection section at a static pressure at least fifty percent (50%) lower than an operating pressure within a reaction chamber (e.g., at a static pressure near ambient pressure).

va Linear edge connector with activator bar and contact load spring By www.freepatentsonline.com Published On :: Thu, 29 Jun 2017 08:00:00 EDT An example apparatus for connecting linear edge cards includes a housing to hold at least one set of conductive contacts facing perpendicularly towards a mating plane. The apparatus further includes an activator bar coupled to the housing, the activator bar to hold two parts of the housing apart via two opposing normal forces. The apparatus also includes a contact load spring coupled to the housing, the contact load spring to apply two forces parallel to the direction of the conductive contacts and against the two opposing normal forces of the activator bar. The apparatus further includes an ejector spring coupled to the contact load spring and the activator bar. The ejector spring is to apply a force perpendicular to the two opposing normal forces of the activator bar and in a direction of an opening of the housing. Full Article
va Plant cultivation apparatus By www.freepatentsonline.com Published On :: Tue, 24 Mar 2015 08:00:00 EDT The present invention discloses an apparatus to simplify an air supply path without damaging the merit of conventional culture apparatus. The apparatus is a culture apparatus which includes a row of a plurality of box-shaped containers for plant cultivation, and a row of lower stage containers arranged in the lower portion of the row, holding the upper stage container spaced as high as the height after growth of the plants to be cultivated. In each container, a support, a blocking film stretched between front and rear, right and left supports of the container are provided. In the one end of the rows of the containers, an air conditioner is arranged, and in another end, a turnaround chamber is provided. Full Article
