    Abstract: 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.

    Abstract translation: 膨胀系统利用其残余的热排气的外部燃烧，以便加热进入的压缩空气。 该外部燃烧的热量通过热交换器传送到输入的压缩空气。 膨胀系统可以结合在还具有由压缩机供应的压缩空气存储单元的能量存储装置中。 在存储的压缩空气供应被耗尽的地方，能量存储装置可以通过作为热机的运行来继续供应电力，其中压缩机被直接驱动（例如在相同的旋转轴上）或间接地（通过产生的电力） 由扩展系统。 相同或不同类型（例如，旋转，往复运动）的多个膨胀器可以根据具体应用并联和/或串联（例如多级）来使用。 在低压阶段具有内燃特性的多级实施例可能特别适合于放置在车辆中。
