Abstract:
1. A microgenerator for use in petroleum distribution systems comprising: a casing defining an interior portion and an exterior portion, said casing having opposed first support wall and second support wall coupled within an inner diameter of a cylinder containment wall; at least one fluid inlet penetrating said cylinder containment wall, said fluid inlet fluidly coupled to an energized fluid source; said energized fluid source selected from the group consisting of a pressurized hydrocarbon, injection fluid, pneumatic control fluid, gas from a gas lift system, steam, or petroleum liquid gas mixture; at least one nozzle fluidly coupled to said fluid inlet, said nozzle configured to accelerate said energized fluid into said interior portion; at least one fluid outlet penetrating said cylinder containment wall, said fluid outlet configured to discharge said petroleum fluid from said interior portion of said casing; an impulse turbine within said interior portion, said impulse turbine having a first stator coupled to said first support wall and a second stator coupled to said second support wall opposite said first stator, a rotor rotatably mounted between said first stator and said second stator on a shaft at a central axis of said rotor, said rotor including an array of turbine blades integral to said rotor at an outer perimeter of said rotor; said at least one nozzle aligned to direct said petroleum fluid against said array of turbine blades to rotate said rotor about said central axis; a set of permanent magnets fixed into said rotor proximate said turbine blades between said perimeter and said shaft; and at least one electromagnetic core and coil assembly fixed into said first stator arranged in a periphery about said central axis and electromagnetically coupled to said set of permanent magnets configured to generate an electric current in cooperation with said set of permanent magnets.
