  • Patent number: 11326550
    Abstract: 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.

  • Patent number: 11313252
    Abstract: A system for repowering a coal fired electrical generation plant with natural gas is disclosed. The plant has having high and low pressure steam turbines that drives an electrical generator. The coal fired plant has a regenerative system comprising a plurality of feedwater heaters that supply heated feedwater to evaporators and superheaters that supply steam to the turbines. The repowering system has a gas turbine that drives a second electrical generator where the HRSG is configured to receive the exhaust from the gas turbine and which is heated by a burner so as to generate steam for driving the steam turbines. The feedwater heaters utilize condensate from the said and from steam extractions to supply heated feedwater to the superheaters that feed superheated steam to turbines such that the first generator driven by the turbines is driven at a high percentage of its rated megawatt output.

  • Patent number: 11313344
    Abstract: A convective power generation device is described based on thermal convection and thermal input energy. The energy generation device operates by heating wax and oil by heat from a solar concentrator or geothermal energy; as the weight of the wax becomes liquid that is lighter than the oil, the liquid wax moves up through a pathway; when the liquid wax reaches the top of the pathway, the cooler wax falls towards collecting cups mounted to a continuous belt and forces the belt downward to rotate the belt; when a collector cup of wax reaches the bottom of belt rotation, the wax falls to a reservoir; and the rotation of the belt drives a gearbox, which drives a generator to produce electric power. The convective power generation device has been shown to have higher energy conversion efficiency than photovoltaics.

  • Patent number: 11300288
    Abstract: The solution comprises a method of and a system for maintaining steam temperature and therefore electricity production efficiency with decreased loads of a steam turbine power plant comprising a fluidized bed boiler (12) and a fluidized bed superheater (2) adapted to superheat steam supplied to a steam turbine (3). According to the solution, the steam temperature may be maintained by providing, outside a furnace (10), additional heating to the fluidized bed material in its outer circulation, thereby increasing the amount of thermal energy available in the fluidized bed material to be transferred in the fluidized bed superheater (2) to the steam supplied to the steam turbine (3). Such additional heating may be performed by selectably supplying combustible gas with nozzles (111) into and/or burned with a burner in or in the vicinity of the fluidized bed material outside the furnace (10). As an additional aspect of the disclosed solution, the combustible gas may be produced with a gasifier (4).
