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 flow of working fluid may be adjusted to a percentage sufficient to maintain temperature of the flow of compressed gas within the selected operating temperature range.

Abstract:
A system and method are provided for storing and recovering electricity generated from conventional/renewable energy sources. A thermal energy storage vessel contains thermal storage fluid (“TSF”) comprising a eutectic ternary nitrate molten salt, induction heating elements, turbine pumps, a heat exchanger, and various data acquisition sensors like thermocouples and thermistors. The immersion heating elements receive the electricity generated from conventional and/or renewable energy source to heat the eutectic ternary nitrate molten salt to the desired temperature. Coiled tubing is deployed within the thermal containment vessel to be distribution systems for the power cycle working gas and heat exchange for the power cycle working gas. The power cycle working gas is delivered under pressure to a steam turbine. The turbine converts the energy into mechanical shaft work to drive an electricity generator to produce electricity. The steam exhaust is gathered by a compressor and returned to the thermal energy storage vessel.
Abstract:
A heat exchanger is for use in an energy recovery system to be mounted on a vessel including an engine, a supercharger and an economizer, the heat exchanger including: a first heat section for heating a working medium by supercharged air from the supercharger; a second heat section for heating the supercharged air by steam generated by the economizer before the supercharged air flows into the first heat section; and a third heat section for heating the working medium having been heated in the first section by the supercharged air which is to be heated in the second section.
Abstract:
A life consumption of a component in a machine may be predicted. Load data may be received from a load session of the machine. A plurality of parameter sets may be accessed, each associated with a critical point of the component, which point is considered to have critical life consumption. For each critical point, life consumption may be calculated using a life consumption calculation model receiving the load data and the parameter sets as input. By selecting a plurality of critical points on the component, a more complete view is presented of how the different parts of the component are affected by the load session.
Abstract:
A hybrid power generation system using a supercritical CO2 cycle includes a steam power generation unit including a plurality of turbines driven with steam heated using heat generated by a boiler to produce electric power, and a supercritical CO2 power generation unit including an S—CO2 heater for heating a supercritical CO2 fluid, a turbine driven by the supercritical CO2 fluid, a precooler for lowering a temperature of the supercritical CO2 fluid passing through the turbine, and a main compressor for pressurizing the supercritical CO2 fluid, so as to produce electric power. The steam power generation unit and the supercritical CO2 power generation unit share the boiler. The hybrid power generation system may improve both the power generation efficiencies of the steam cycle and the supercritical CO2 cycle by interconnecting the steam cycle and the supercritical CO2 cycle.

The invention relates to a method for controlling ORC stacks with a total number ntot of individually operable ORC modules, said method comprising the following steps: determining the running time remaining until the next servicing time for each operable ORC module respectively; determining a target number nsoll of ORC modules to be operated; comparing said target number nsoll to an actual number nist of currently operated ORC modules; when nsoll>nist, connecting a number nsoll−nist of ORC modules that corresponds to the difference between the target number and the actual number, where the ORC modules with the longest remaining running times of the ORC modules currently not being operated are connected; and/or when nsoll Δt2.
Abstract:
Systems and methods are provided for the recovery mechanical power from heat energy sources using a common working fluid comprising, in some embodiments, an organic refrigerant flowing through multiple heat exchangers and expanders. The distribution of heat energy from the source may be portioned, distributed, and communicated to each of the heat exchangers so as to permit utilization of up to all available heat energy. In some embodiments, the system utilizes up to and including all of the available heat energy from the source. The expanders may be operatively coupled to one or more generators that convert the mechanical energy of the expansion process into electrical energy, or the mechanical energy may be communicated to other devices to perform work.
Abstract:
An overheating detection processing system monitors in real time and stores data samples from the different types of power plant overheating detectors. The system determines a likelihood of whether a stored detector output sample reading, alone or in combination with other readings, is indicative of monitored power plant equipment overheating. The system references previously stored information in an information storage device that associates respective types of detector sample reading levels with equipment overheating. The system also compares a combination of stored sample readings and establishes overheating determination confidence levels. The confidence levels information is combined to derive an overall confidence level of whether the power plant equipment is overheated. An overheating alarm response is initiated if an overheating condition is determined at any confidence level. Additional responses are made based on a combination of calculated confidence levels.
