Title: Single shaft microturbine power generating system including turbocompressor and auxiliary recuperator

Abstract: A microturbine power generating system includes a primary compressor, an electrical generator and a turbine that can be rotated as a unit. Hot, expanding gases resulting from combustion are expanded through the turbine, and the resulting turbine power is used for powering the electrical generator. The microturbine power generating system further includes an auxiliary compressor that is driven by the turbine power. During operation of the system, a small portion of air can be bled off the primary compressor and further compressed in the auxiliary compressor to provide an auxiliary supply of pressurized air. The heat of high pressure compression is recovered to increase the overall efficiency of the machine.
