| 20150322857 | MICRO GAS TURBINE SYSTEMS AND USES THEREOF - The present disclosure describes a micro gas turbine flameless heater, in which the heat is generated by burning fuel in a gas turbine engine, and the heater output air mixture is generated by transferring the heat in the gas turbine exhaust to the cold air drawn from the ambient environment. The present disclosure also describes component geometries and system layout for a gas turbine power generation unit that is designed for simple assembly, disassembly, and component replacement. The present disclosure also allows for quick removal of the rotating components of the gas turbine engine in order to reduce assembly and maintenance time. Furthermore, the present disclosure describes features that help to maintain safe operating temperatures for the bearings and structures of the gas turbine engine power turbine. Lastly, the present disclosure describes features of a fuel capture system that allow the injection of wellhead gas, which typically is a mixture of gaseous and liquid fuels, into the combustion chamber, and also describes methods of incorporating afterburners in the gas turbine engine, such that the gas turbine engine system can use wellhead gas to power equipment and reduce emissions from flaring in oil and gas applications. | 11-12-2015 |

| 20150345422 | THERMODYNAMICALLY INTERACTIVE HEAT FLOW PROCESS AND MULTI-STAGE MICRO POWER PLANT - A high efficiency, thermodynamically interactive power system incorporating a “thermodynamic battery” operating in the cryogenic range. The “thermodynamic battery” is drawn upon to optimize the efficiency of power generation during times of peak demand and is “recharged” during periods of low demand. The system is ideally suited for (although not limited to) micropowerplants suitable for widely distributed generation of power in or associated with homes and small businesses, reducing transmission loading on the grid and capable of supplying power into the grid during peak load periods. The widely distributed power generation made practical by present inventions also enables distribution of heating and chill service locally on a much larger scale than is possible with large, centralized generation plants. A novel form of gear pump mechanism makes possible inexpensive and effective multi-stage compression and expansion of gaseous working fluid particularly suitable for incorporation into micropowerplants for distributed and localized power generation. | 12-03-2015 |
