Abstract:
A compressor system for production of compressed air to a compressed air discharge point, said system comprising:a first exhaust turbocharger having a first turbine side and a first compressor side, coupled to the exhaust of an internal combustion engine, said first exhaust turbocharger configured to provide precompressed air to said internal combustion engine; and a second exhaust turbo charger having a second turbine side and a second compressor side, coupled in line to a first turbine side exhaust output of said first exhaust turbocharger, said second exhaust turbocharger configured to provide precompressed air to a liquid-injected displacement compressor, wherein said first turbine side of said first exhaust turbocharger has a wheel geometry that is a function of the exhaust backpressure on said internal combustion engine and the temperature resulting from said second exhaust turbocharger and wherein said second turbine side of said second exhaust turbocharger is a function of the mass flow from said first turbine side of said first exhaust turbocharger and the mass flow required by said second compressor side of said second exhaust turbocharger to support said compressor.
