摘要： Systems and generating power in an organic Rankine cycle (ORC) operation to supply electrical power. In embodiments, an inlet temperature of a flow of gas from a source to an ORC unit may be determined. The source may connect to a main pipeline. The main pipeline may connect to a supply pipeline. The supply pipeline may connect to the ORC unit thereby to allow gas to flow from the source to the ORC unit. Heat from the flow of gas may cause the ORC unit to generate electrical power. The outlet temperature of the flow of the gas from the ORC unit to a return pipe may be determined. A bypass valve, positioned on a bypass pipeline connecting the supply pipeline to the return pipeline, may be adjusted to a position sufficient to maintain temperature of the flow of gas above a threshold based on the inlet and outlet temperature.

摘要： A system for electricity generation using heat contained in exhaust gas from a combustor (enclosed flare) to drive an external combustion Stirling cycle engine which directly drives at least one alternator or generator. A battery is connected to the alternator or generator through a divider circuit followed by a filter circuit. Electric power distribution circuits are electrically connected to output circuits of the alternators or generators for consumption of the electric power on-site, for sale to a commercial electric power distribution grid, or for any other desired uses.

摘要： A catalytic burner comprising a burner chamber and a utilization chamber, the burner chamber functionally divided into a fuel-oxidant mixing zone and a catalytic combustion zone. The burner chamber occupies a space disposed between outer and inner tubular walls of the burner. The utilization chamber, which is a space bounded by the inner tubular wall, remains hollow for secondary useful purposes, for example, connection to a heat sink of a Stirling engine and/or incorporation of a second heat source (e.g., solar or geothermal heat source). Auxiliary system components can also be packaged into the utilization chamber. The burner can function in hybrid flame and/or flameless modes, and can further include a recuperator to capture heat by-passing the heat sink.

摘要： A container-type compressed air storage power generation device (2) comprises compressors (5a-5c); a tank (8); power generators (9a-9c); a control device (12); and a container (4). The compressors (5a-5c) compress air. The tank (8) is driven by air supplied from the compressors (5a-5c). The power generators (9a-9c) are driven by air supplied from the tank (8). The control device drives and controls the compressors (5a-5c) and the power generators (9a-9c). The container (4) houses the compressors (5a-5c) and the power generators (9a-9c), and the tank (8) is disposed outside the container (4). Therefore, the container-type compressed air storage power generation device (2) is easy to transport and construct on-site.

摘要： The present invention provides a heat medium circulation structure for a micro-combined heat and power (micro-CHP) generator in which a heat medium that primarily looses heat by undergoing heat exchange with water in a hot-water tank and thus has a low temperature further performs heat exchange with low-temperature direct water supplied through a direct water line, thereby further loosing heat, in a return line heat exchanger, and then returns to a stirling engine through a heat medium return line, thereby effectively cooling a low temperature portion of the stirling engine. Thus, the heat medium circulation structure enables high electricity production efficiency. Further provided is a hot water temperature control method for a micro-CHP generator in which the consumption of hot water is detected by a flow sensor. First and second predetermined temperatures are defined to operate a stirling engine in the case of temperature droppings of hot water respectively due to natural radiation and consumption of hot water.
