20090019853 | Method and Arrangement for Energy Conversion in Stages - A flexible method and arrangement provides an effective conversion of energy from any kind of energy sources and/or fuels by combustion and/or gasification, during long-term sustainable economy and environment, by energy conversion in stages. With an open partially circulated condensate system and/or a closed circulation feed water system, stages include first stage of conversion by gasification/combustion, pressurized and/or atmospheric with or without steam- and/or gas-turbines and/or pressurized fuel cell, followed by a second stage of conversion, which second stage utilizing condensation cooling including direct and/or indirect heat transmissions by the first stage produced pressurized mass flow of primary/secondary/residual heat comprising sensible and latent heat, by means of arrangement of expander turbines including counter current fed feed water/condensate fractions during preheating of condensate and feed water respectively before the return to the first stage of conversion. The expander turbines of the second stage with or without co-operation by a third stage of integrated heat transmissions together with the first and second stages effectively transform the mass flow of primary/secondary/residual heat/gas into bio-fuels, mechanical energy as electric power via turbine connected generators, or driving mobile machines/vehicular—a hybrid type of rotation motor during continuous combustion. | 01-22-2009 |
20090272115 | Method of Utilization of Gas Expansion Energy and Utilization Power Installation for Implementation of this Method - A method and installation are provided for reduction of natural gas from high pressure, such as in a borehole or in a main pipeline down to the pressure valve required for the consumer. | 11-05-2009 |
20110271677 | HYBRID POWER PLANT WITH WASTE HEAT RECOVERY SYSTEM - A hybrid power plant includes a waste heat recovery (WHR) system having an expander driven by waste heat from an internal combustion engine. The expander, which is rotary in one example, rotationally drives a first pump and alternator with which the expander may be packaged as a single unit. The first pump circulates a working fluid when the WHR system is in use to charge an electrical storage device. A second pump is employed to circulate the working fluid when the first pump is not in use, for example. The expander can be bypassed to divert the working fluid to a heater core used to heat engine coolant during cold start conditions, for example. | 11-10-2011 |
20130091845 | POWER PLANT AND METHOD FOR RETROFIT - A power plant includes a first gas turbine engine, a second gas turbine engine, a flue gas duct, a CO | 04-18-2013 |
20130145764 | SYSTEMS AND METHODS FOR EFFICIENT TWO-PHASE HEAT TRANSFERIN COMPRESSED-AIR ENERGY STORAGE SYSTEMS - In various embodiments, foam is compressed to store energy and/or expanded to recover energy. | 06-13-2013 |
20140196457 | CERAMIC-TO-METAL TURBINE SHAFT ATTACHMENT - A metallic-ceramic joint for a turbo-compressor spool is disclosed. A temperature-limited joint is moved from outside the bearings to between the bearings and near the center of the shaft joining the turbine and compressor. This placement can lower the temperature at and around the joint and reduces the sharp gradient (and associated thermal stress) naturally occurring between the turbine rotor and the cooler joint. The bearing closest to the compressor can be an oil bearing and the bearing closest to the turbine an air bearing. The bearing closest to the compressor and the bearing closest to the turbine can both be an oil bearing. The bearing closest to the compressor and the bearing closest to the turbine can both be an air bearing. Moving the metallic-ceramic joint between the bearings can provide sufficient isolation to enable the all-air bearing solution. | 07-17-2014 |
