摘要： An expansion system utilizes external combustion of its residual warm exhaust air, in order to heat incoming compressed air. The heat of this external combustion is communicated to the incoming compressed air through a heat exchanger. The expansion system may be incorporated into an energy storage device also featuring a compressed air storage unit supplied by a compressor. Where the stored supply of compressed air is depleted, the energy storage device may continue to supply electricity on demand through operation as a heat engine, with the compressor being driven directly (e.g. on a same rotating shaft) or indirectly (via generated electrical power) by the expansion system. Multiple expanders of the same or different types (e.g. rotating, reciprocating), may be utilized in parallel and/or in series (e.g. multiple stages) depending upon the particular application. Multi-stage embodiments featuring internal combustion in low pressure stages, may be particularly suited for placement in vehicles.

摘要： An apparatus performs a power cycle involving expansion of compressed air utilizing high pressure (HP) and low pressure (LP) air turbines located upstream of a gas turbine. The power cycle involves heating of the compressed air prior to its expansion in the HP and LP air turbines. Taking into consideration fuel consumption to heat the compressed air, particular embodiments may result in a net production of electrical energy of ˜2.2-2.5× an amount of energy consumed by substantially isothermal air compression to produce the compressed air supply. Although pressure of the compressed air supply may vary over a range (e.g. as a compressed air storage unit is depleted), the gas turbine may run under almost constant conditions, facilitating its integration with the apparatus. The air turbines may operate at lower temperatures than the gas turbine, and they may include features of turbines employed to turbocharge large reciprocating engines.
