20150107249 | Extracting Heat From A Compressor System - A system includes a gas compressor system and a thermal cycle. The gas compressor system includes a compressor housing defining an interior compressor chamber. A gas compressor is in the interior compressor chamber to compress gas received into interior compressor chamber. A heat exchange fluid passage is provided adjacent to a surface that contacts the gas being compressed by the gas compressor. The thermal cycle includes a working fluid heated using the heat exchange fluid passage of the compressor housing. The working fluid is expanded by the thermal cycle to generate electricity. | 04-23-2015 |
20140028033 | THERMAL CYCLE ENERGY AND PUMPING RECOVERY SYSTEM - 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. | 01-30-2014 |
20130234439 | HEAT RECOVERY USING RADIANT HEAT - 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. | 09-12-2013 |
