Abstract: Systems, methods, and apparatuses may involve a burner configured to burn gas to produce burned gas and output radiant heat. A gas valve controlled by the system can regulate the flow of gas to the burner. A heat exchanger associated with a thermal cycle can be used to heat a working fluid of the thermal cycle. The heat exchanger positioned out of a convective heat flow from the burner. A heat valve between the burner and the heat exchanger can be selectively adjustable to adjust heat transfer to the heat exchanger.

Abstract: Systems, methods, and apparatuses for pressure recovery and power generation may include a pressure recovery generator configured to receive a high-pressure fluid and generate current based on expansion of the high-pressure fluid. The current may be directed to a power electronics module that is configured to receive current from the pressure recovery generator and provide current to a closed-loop thermal cycle, such as an ORC. The current can be used to start components of the closed-loop thermal cycle, such as the pump and/or to black start the turbine generator. In some instances, the current can be combined with current generated by the closed-loop thermal cycle and directed to a utility grid or to external loads. The high-pressure fluid may be directed to heat exchanger components of the closed-loop cycle. For example, high-pressure, high-temperature fluid can be directed to an evaporator, while high-pressure, low-temperature fluid can be directed to a condenser.

Abstract: Systems, methods, and apparatuses for controlling a thermal fluid condition may include monitoring a thermal fluid at an outlet of a heat exchanger. An outlet condition of the thermal fluid at the outlet of the heat exchanger can be determined. The outlet condition of the thermal fluid can be provided to a controller of a closed-loop thermal cycle. A condition of the thermal fluid at an inlet to the heat exchanger can be adjusted based on the outlet condition of the thermal fluid.

Abstract: A gas burner system may include a first burner configured to burn gas to produce burned gas in a first portion of the waste gas burner system and a second burner configured to burn gas to produce burned gas in a second portion of the waste gas burner system. A heat exchanger may reside out of the first portion and may be configured to receive heat from the burned gas in the second portion and heat a working fluid of a thermal cycle system. A valve may be configured to control an amount of gas provided to the second burner. The gas may be a waste gas from a process. The thermal cycle system may include an organic Rankine cycle.

Abstract: An electric machine system includes an electric machine and a companion device. The electric machine has a stationary member and a movable member that, by interaction of magnetic fields, at least one of moves relative to the stationary member or generates electricity when moved relative to the stationary member. One of the stationary member and the movable member includes a permanent magnet. The companion device is coupled to the electric machine to communicate mechanical movement with the movable member. In certain instances, the electric machine system has adaptations for operation of the electric machine system subsea and/or in a corrosive environment.
