Abstract: A process for increasing the specific output of a combined cycle power plant and providing flexibility in the power plant rating, both without a commensurate increase in the plant heat rate, is disclosed. The present invention demonstrates that the process of upgrading thermal efficiencies of combined cycles can often be accomplished through the strategic use of additional fuel and/or heat input. In particular, gas turbines that exhaust into HRSGs, can be supplementally fired to obtain much higher steam turbine outputs and greater overall plant ratings, but without a penalty on efficiency. This method by and large defines a high efficiency combined cycle power plant that is predominantly a Rankine (bottoming) cycle. Exemplary embodiments of the present invention include a load driven by a topping cycle engine, powered by a topping cycle fluid which exhausts into a heat recovery device.

Abstract: To meet emissions standards, many gas turbine engines use some form of lean, pre-mixed combustion system. The lean nature of the fuel may lead to combustion oscillations or other instabilities. A fuel injector having an inner and outer cylinder receives pilot fuel and a portion of pre-mixed fuel-air into an annular space defined by the inner and outer cylinders. The amount of pilot fuel mixed with the pre-mixed fuel-air can be modulated based on sensed conditions within the turbine engine. Continuous modulation of the pilot fuel to adapt to the sensed conditions improves main burner flames and response to engine transients.

In one implementation, the controller is configured to engage compression immediately upon detecting that the vehicle is decelerating. One or more kits can be used to retrofit existing vehicles to operate the respective air conditioning systems principally on waste energy.

Abstract: Implementations of the present invention include systems, methods, and apparatus for improving the fuel efficiency (mpg/kpl) of a motor vehicle during those times when the vehicle air conditioning system is operating. Whenever the driver takes his foot off the gas, or the vehicle engine is otherwise caused to decelerate, the refrigerant compressor clutch engages, allowing the compressor to operate on previously-imparted vehicle waste energy (e.g., imparted by the engine, or by downhill travel.) When the refrigerant pressure reaches a pre-set maximum value, the clutch is deactivated, and the compressor stops. When the refrigerant pressure reaches a pre-set minimum level, the clutch is activated regardless of the existence of vehicle waste energy. When the refrigerant pressure reaches another pre-set level between the aforementioned maximum and minimum levels, in the absence of any vehicle waste energy, the clutch is again deactivated and the compressor stops.
