摘要:
An exhaust heat recovery device for an engine including a Rankine cycle, including a steam accumulator that stores a surplus of a working medium for driving a turbine, and a leveling line that discharges the stored surplus working medium from the steam accumulator to the turbine, when the turbine cannot output predetermined power only with the working medium flowing out from a boiler, and levels the power outputted from the turbine. Since the power outputted from the turbine can be leveled without reduction of the power, even if the working medium cannot vaporize with the boiler immediately after start-up, immediately before stop, or during a low-load operation of the engine, exhaust heat from the engine can be efficiently used.

An integrated fuel combustion system with adsorptive gas separation separates a portion of carbon dioxide from a combustion gas mixture and provides for recycle of separated carbon dioxide to the intake of the fuel combustor for combustion. A process for carbon dioxide separation and recycle includes: admitting combustion gas to an adsorptive gas separation system contactor containing adsorbent material; adsorbing a portion of carbon dioxide; recovering a first product gas depleted in carbon dioxide for release or use; desorbing carbon dioxide from the adsorbent material and recovering a desorbed second product gas enriched in carbon dioxide for sequestration or use; admitting a conditioning fluid into the contactor and desorbing a second portion of carbon dioxide to recover a carbon dioxide enriched conditioning stream; and recycling a portion of the carbon dioxide enriched conditioning stream to an inlet of fuel combustor to pass through the fuel combustor for combustion.
摘要:
A method for tuning a system of cascade oscillating vapor traps to utilize the high-pressure condensate and produce intermittent power output on the basis of the physicochemical line of Retrograde Condensation in the two-phase zone. The method is based on usage of the “natural” frequencies, defined by the fluid on every point on said line and is radically different from the way steam traps are tuned presently.

It is an object to supply stable motive power to a compressor even if load variations have occurred in an electric power station. Provided is a CO2 recovery system equipped with a CO2 compressor 12 that compresses recovered CO2 removed by a CO2 recovery unit 11, a steam turbine 13 that supplies motive power to the CO2 compressor 12, and an auxiliary motor 14 that, if there is a shortage of the motive power from the steam turbine 13, supplies the CO2 compressor with motive power in an amount corresponding to the shortage.
摘要:
A fossil-fueled power station including a steam generator is provided. A steam turbine is mounted downstream of the steam generator via a hot intermediate superheater line and a carbon dioxide separation device. The carbon dioxide separation device is connected to the hot intermediate superheater line via a process steam line and a backpressure steam turbine is mounted into the process steam line.

A power plant, in the form of a combined heat and power (CHP) plant, may be co-located with a data center to provide redundant electrical power. The CHP plant and the data center may operate as an island, separate from the local electrical-utility grid. The CHP plant may have a redundant fuel source connection to reduce unavailability of fuel for the CHP and increase the uptime of the data center. The CHP plant may include turbines and engines to manage variable loads within the data center. The power plant may include multiple distributions busses in high-availability configurations to provide highly-reliable and high-quality electricity to the data center. The positioning of these elements in the power plant design provides economies of scale and eliminates single points of failure commonly found in data center configurations, increasing the reliability of the data center.
摘要:
Energy is recovered from steel products produced in a steel mill where the products are transported into a storage area by first extracting heat from the steel products prior to or after transport into the storage area by heat exchangers for a predetermined period in which residual heat of the steel products is transferred by the heat exchangers into a heat-transfer medium to heat same. The heated transfer medium is then transferred via heat-transfer transport lines for power generation or for direct use of the process heat in other heat consumers. This transport of the heat-transfer medium from the heat exchangers to the power-generating plant in the heat-transfer transport lines is carried out only at pump feed pressure or using as a heat-transfer medium liquid mineral or synthetic thermal oil or a salt melt so as not to build up a steam pressure above 2 bar.

摘要:
The disclosure relates to a system and a method for planning the operation of, monitoring processes in, simulating, and/or optimizing a technical installation comprising several units that can be combined with each other. Said system comprises at least one process planning module, at least one process simulation module, and at least one process optimization module. Components for modeling, simulating, and optimizing the technical installation are stored in said modules. The interrelated modules cooperate with a data management layer via at least one interface, said data management layer making available actual measured and/or historical process data for determining parameters and/or operational data for the modules in order to plan operations as well as simulate and optimize processes. The parameters and/or operational data determined in the modules can be fed to the data management layer for further processing by taking into account the stored components.
