Patent number: 8631657Abstract: Thermodynamic cycles with diluent that produce mechanical power, electrical power, and/or fluid streams for heating and/or cooling are described. Systems contain a combustion system producing an energetic fluid by combusting fuel with oxidant. Thermal diluent is preferably used in the cycle to improve performance, including one or more of power, efficiency, economics, emissions, dynamic and off-peak load performance, temperature regulation, and/or cooling heated components. Cycles include a heat recovery system and preferably recover and recycle thermal diluent from expanded energetic fluid to improve cycle thermodynamic efficiency and reduce energy conversion costs. Cycles preferably include controls for temperatures, pressures, and flow rates within a combined heat and power (CHP) system, and controls for power, thermal output, efficiency, and/or emissions.Type: GrantFiled: October 10, 2006Date of Patent: January 21, 2014Assignee: Vast Power Portfolio, LLCInventors: David L. Hagen, Gary Ginter, Alberto Traverso, Bill Goheen, Allan McGuire, Janet Rankin, Aristide Massardo, Ronald L. Klaus

Patent number: 8192688Abstract: A thermally diluted exothermic reactor system is comprised of numerous orifices distributed within a combustor by distributed perforated contactor tubes or ducts. The perforated contactors deliver and mix diluent fluid and one or more reactant fluids with an oxidant fluid. Numerous micro-jets about the perforated tubes deliver, mix and control the composition of reactant fluid, oxidant fluid and diluent fluid. The reactor controls one or more of composition profiles, composition ratio profiles and temperature profiles in one or more of the axial direction and one or two transverse directions, reduces temperature gradients and improves power, efficiency and emissions.Type: GrantFiled: March 26, 2009Date of Patent: June 5, 2012Assignee: Vast Power Portfolio LLCInventors: David L.

Publication number: 20050056313Abstract: The invention relates in general to methods of controlled mixing one fluid with another. In particular it relates to a distributed direct fluid contactor including arrays of streamlined perforated tubes distributed across a flow to efficiently contact and mix one or more fluids flowing through one or more tubes with a second fluid flowing across those tubes. These distributed contactors thereby mix the fluids in a fairly uniform fashion causing a prescribed uniformity or variation in the ratio of the first to second fluid across the space. This thereby to generally creates and controls the physical and/or chemical changes in those fluids, including evaporation, condensation, forming powders and conducting chemical reactions including combustion.Type: ApplicationFiled: October 15, 2003Publication date: March 17, 2005Inventors: David Hagen, Gary Ginter, Bill Goheen, Allan McGuire, Janet Rankin

In particular it relates to a distributed direct fluid contactor including arrays of streamlined perforated tubes distributed across a flow to efficiently contact and mix one or more fluids flowing through one or more tubes with a second fluid flowing across those tubes. These distributed contactors thereby mix the fluids in a substantially uniform fashion causing a prescribed uniformity or variation in the ratio of the first to second fluid across the space. This thereby to generally creates and controls the physical and/or chemical changes in those fluids, including evaporation, condensation, forming powders and conducting chemical reactions including combustion.Type: ApplicationFiled: September 12, 2003Publication date: December 9, 2004Inventors: David L.

Patent number: 5437729Abstract: A method for tailoring or patterning the surface of ceramic articles is provided by implanting ions to predetermined depth into the ceramic material at a selected surface location with the ions being implanted at a fluence and energy adequate to damage the lattice structure of the ceramic material for bi-axially straining near-surface regions of the ceramic material to the predetermined depth. The resulting metastable near-surface regions of the ceramic material are then contacted with energy pulses from collapsing, ultrasonically-generated cavitation bubbles in a liquid medium for removing to a selected depth the ion-damaged near-surface regions containing the bi-axially strained lattice structure from the ceramic body.Type: GrantFiled: April 8, 1993Date of Patent: August 1, 1995Assignee: Martin Marietta Energy Systems, Inc.Inventors: Lynn A.
