Fuel, oxidant and reactant for a supercritical water oxidation reactor are fed through an injector in which the flow are arranged such that the oxidant feed surrounds the fuel feed and the shields the fuel feed from the reactant feed. Excessive reactant temperature is thus avoided, and the reaction can proceed in a highly efficient manner.

Injector for SCWO reactor

A micropore filter of discrete flow-through pores of highly controlled pore configuration and dimensions is formed by bonding platelets into a laminate, each platelet having been etched, preferably by a combination of electropolishing and photoetching techniques, to form depth-etched passages and through-etched passages, respectively. The filter is housed in a module which contains wiper blades for periodically removing deposited debris from the filter surface.

Discrete pore platelet filter manufactured by electropolishing

A reactor tube for supercritical water oxidation is designed to supply a thin, continuous layer of water along the inner surface of the reaction zone by a wall lining formed of laminated platelets individually etched and superimposed to form an array of engineered fluid passages through the wall. Each passage includes a flow metering channel of closely controlled configuration to impose a preselected level of resistance to water flowing through it, plus a distribution section which distributes the water emerging from the flow metering channel over the length of a slot-shaped exit port. The exit port is arranged in conjunction with neighboring exit ports in an array over the inner surface of the reactor such that the emerging water forms a continuous film over the surface, thereby protecting the surface from corrosion and salts deposition from the supercritical reaction medium.
