| 20100083662 | METHOD AND APPARATUS FOR THE UTILIZATION OF WASTE HEAT FROM GASEOUS HEAT SOURCES CARRYING SUBSTANTIAL QUANTITIES OF DUST - An apparatus, system and method for transferring heat from a hot flue gas stream from a cement plant including large particles and dust to a working fluid of a power plant via a high temperature heat transfer fluid without exposing all or most of the equipment to the erosive force of the particles and dust is disclosed where the apparatus includes a cement plant, a particle separation and heat transfer system and a power plant | 04-08-2010 |
| 20100101227 | POWER SYSTEMS AND METHODS FOR HIGH OR MEDIUM INITIAL TEMPERATURE HEAT SOURCES IN MEDIUM AND SMALL SCALE POWER PLANTS - Power generation systems and methods are disclosed for use with medium to high temperature heat source stream, gaseous or liquid, where the systems and methods permit efficient energy extraction for medium and small scale power plants. | 04-29-2010 |
| 20100122533 | METHOD AND SYSTEM FOR CONVERTING WASTE HEAT FROM CEMENT PLANT INTO A USABLE FORM OF ENERGY - Methods and systems for converting waste heat from cement plant into a usable form of energy are disclosed. The methods and systems make use of two heat source streams from the cement plant, a hot air stream and a flue gas stream, to fully vaporize and superheat a working fluid stream, which is then used to convert a portion of its heat to a usable form of energy. The methods and systems utilize sequential heat exchanges stages to heat the working fluid stream, first with the hot air stream or from a first heat transfer fluid stream heated by the hot air stream and second with the flue gas stream from a second heat transfer fluid stream heated by the hot air stream. | 05-20-2010 |
| 20100146973 | POWER SYSTEMS AND METHODS FOR HIGH OR MEDIUM INITIAL TEMPERATURE HEAT SOURCES IN MEDIUM AND SMALL SCALE POWER PLANTS - Power generation systems and methods are disclosed for use with medium to high temperature heat source stream, gaseous or liquid, where the systems and methods permit efficient energy extraction for medium and small scale power plants. | 06-17-2010 |
| 20100205962 | SYSTEMS, METHODS AND APPARATUSES FOR CONVERTING THERMAL ENERGY INTO MECHANICAL AND ELECTRICAL POWER - The present invention discloses systems and methods for converting heat from external heat source streams or from solar energy derived from a solar collector subsystem. The systems and methods comprise a thermodynamic cycle including three internal subcycles. Two of the subcycles combine to power a higher pressures turbine and third or main cycle powers a lower pressure turbine. One of the cycles increases the flow rate of a richer working solution stream powering the lower pressure turbine. Another one of the cycles is a leaner working solution cycle, which provides increased flow rate for leaner working solution stream going into the higher pressure turbine. | 08-19-2010 |
| 20110024084 | DIRECT CONTACT HEAT EXCHANGER AND METHODS FOR MAKING AND USING SAME - A direct heat exchange method and apparatus for recovering heat from a liquid heat source is disclosed, where the method includes contacting a liquid heat source stream with a multi-component hydrocarbon fluid, where the hydrocarbon fluid compositions has a linear or substantially linear temperature versus enthalpy relationship over the temperature range of the direct heat exchange apparatus. | 02-03-2011 |
| 20110067400 | DIRECT CONTACT HEAT EXCHANGER AND METHODS FOR MAKING AND USING SAME - A system and method are disclosed for the combined production of power and heat from an external heat source stream, where the system utilizes four basic stream of different compositions to co-generate power and to heat an external heat absorber stream from an external heat source stream. | 03-24-2011 |
| 20110174296 | SOLAR-THERMAL ENERGY STORAGE SYSTEM AND METHODS OF MAKING AND USING SAME - Solar-thermal energy storage systems and methods are disclosed including a heat transfer fluid storage and distribution subsystem (HTFSDSS) including at least N storage tanks, control valves, and transfer lines, a solar heating or collector subsystem (SHSS) connected to the HTFSDSS via the transfer lines, and a heat conversion or power subsystem (HCSS) connected to the HTFSDSS via the transfer lines, where at least one of the N tanks is empty at the start of an operational cycle and heat transfer fluid is forwarded from filled tanks in the HTFSDSS through the other subsystem and into the empty tank or tanks. | 07-21-2011 |
