Microgenerator for hydrocarbon producing systems

摘要

A microgenerator for use in petroleum distribution systems includes a casing defining an interior portion and an exterior portion. The casing has an opposed first support wall and second support wall coupled within an inner diameter of a cylinder containment wall. At least one fluid inlet penetrates the cylinder containment wall. The fluid inlet is fluidly coupled to an energized fluid source. At least one nozzle is fluidly coupled to the fluid inlet. The nozzle is configured to accelerate the fluid into the interior portion. At least one fluid outlet penetrates the cylinder containment wall. The fluid outlet is configured to discharge the fluid from said interior portion of the casing. An impulse turbine is located within the interior portion. The turbine has a first stator coupled to the first support wall and a second stator coupled to the second support wall opposite the first stator. A rotor is rotatably mounted between the first stator and the second stator on a shaft at a central axis of the rotor. The rotor includes an array of turbine blades integral to the rotor at an outer perimeter of the rotor. The nozzle is aligned to direct the fluid against the array of turbine blades to rotate the rotor about the central axis. A set of permanent magnets are fixed into the rotor proximate the turbine blades between the perimeter and the shaft. At least one electromagnetic core and coil assembly is fixed into the first stator arranged in a periphery about the central axis and is electromagnetically coupled to the set of permanent magnets and is configured to generate an electric current in cooperation with the set of permanent magnets.
