Since the Stirling engine is a closed cycle
, it contains a fixed mass of gas called the "working fluid", most commonly air, hydrogen or helium.
Approximating a thermodynamic Brayton cycle, the closed cycle
gas turbine has two heat exchangers, one for rejecting heat from working fluid entering the compressor and one for energy addition to flow entering the turbine.
Also discussed are the staging of compressors for reduction of hp in air conditioning systems, the Closed Cycle
heat pump to transfer heat within a project and volumatic control.
As part of the overall improvements, Anomatic has: improved its ability to deliver environmentally-friendly packaging; up to 40% of process water is recycled and reused via advanced recycling technologies, reducing demand for potable water throughout the company's processes; new closed cycle
vapor technology cleaning system reduces 92% of carbon based energy for equivalent cleaning of raw parts prior to anodizing and recovers 80-90% of stamping oil for reuse; upgrading waste water treatment system to "semi-intelligent" PLC logic-based control lowered chemical usage by improving operation and automated control; and current air scrubber technology removes more than 98% of nitrogen oxides, operating at less than 40% of EPA permits.
The plant's water pollutant discharge regulation is under review for renewal by EPA Region I, and CLF is actively working to ensure that the permit requires the adoption of closed cycle
cooling as the best technology available.
The Everdry FRL as a "closed-loop" dryer with its cooling in a closed cycle
is suitable even for the application under tropical climatic conditions.
In a major victory for environmentalists, fishers, and the public, the court found that regulations issued by the EPA in 2004 improperly rejected "closed cycle
cooling," a technology that cools plant machinery while nearly eliminating the need for large infusions of flesh water.
Hydrogenics Corporation recently announced it has sold a lightweight, five-kilowatt (kW) hydrogen/oxygen proton exchange membrane (PEM) fuel cell stack to the NASA Glenn Research Center, for use in an experimental closed cycle
hydrogen-oxygen regenerative fuel cell.
The company says thousands of ORMAT[R] Energy Converters (OEC), known also as Closed Cycle
Vapor Turbogenerators (CCVT)--fueled by gas from wells or pipelines--provide continuous electric power for unmanned offshore platforms and for pipeline cathodic protection and SCADA.
The sustainability of the closed cycle
makes sense, the juxtaposition of gardens and moods is a delight, the remorseless logic humorous, but the question is raised: 'will all of life be managed and pharmed?' No wonder a vocal group in Holland want more wilderness (MVRDV).
Application: This study supports efforts to control non-process elements in closed cycle
(NYSE: APD) has developed a new brochure on its breakthrough Closed Cycle
Air Refrigeration (CCAR [TM]) technology, showcasing the system's capabilities for flexible, cost-effective and environmentally-friendly food freezing.
