Patent number: 11448399Abstract: An electronically controlled burner management system for oilfield separators. The system includes an autonomous standing pilot spark ignition that includes a self-aligning clamp that holds the igniter to the burner nozzle. The self-aligning clamp enables rapid installation and removal, lowering the total cost of ownership. The autonomous spark ignition system incorporates temperature sensors to determine when the standing pilot needs to be relit, and can shut off the gas or other fuel flow to the standing pilot and the main burner when the pilot is not lit. The system increases oil and gas production from the well, reduces fugitive emissions of unburned gas, and improves oilfield worker safety. When installed or retrofitted into an existing oilfield separator, the original burner control components are left in place, allowing the user to revert to traditional operation in case of failure of any electronic component of the present system.Type: GrantFiled: November 21, 2019Date of Patent: September 20, 2022Assignee: Dragonfire Technologies, Inc.Inventors: Ryan Davis, Steven Strohl, Ty Davis, William F. Clark

Patent number: 10042374Abstract: Method and apparatus are provided for determining a grid condition, such as a weakened grid condition, and controlling a power plant, such as a wind or solar power plant, in a manner which is appropriate to the grid condition. The method includes measuring (14) output parameters of a generator, such as a wind turbine or PV generator. The measured output parameters include reactive power and voltage. The method further includes determining (16) a relationship between the measured output parameters of the generator. The relationship between the measured output parameters of the generator is indicative of a condition of a power grid to which the plant supplies power. The method allows controlling (18) the plant responsive to the relationship between the measured output parameters of the generator to avoid onset of oscillatory behavior, which could otherwise occur in the power plant in the presence of a weakened grid condition.Type: GrantFiled: June 13, 2014Date of Patent: August 7, 2018Assignee: Siemens Gamesa Renewable Energy A/SInventors: Robert J.
