A turbine-driven alternator (i.e., a turbomachine) suitable for generating electrical power from process gas waste energy. In particular suitable for very high density process gases such as super critical CO2, R134a, R245fa, etc. The turboalternator comprises two separate machines, specifically, a turbine device and an alternator device operatively connected together by a coupling shaft. The rotating shaft assemblies for each machines on the turbine side and the alternator side are supported by hydrodynamic foil gas bearings. The foil gas bearings use pr...
1. A turbomachine comprising: a turbine including:a turbine housing having an inlet for receiving a process gas at a first pressure and having an outlet for discharging the process gas at a second pressure, wherein said second pressure is lower than said first pressure;a rotating shaft mounted within the turbine housing for rotation about a central longitudinal axis, said rotating shaft being radially supported by at least one journal bearing assembly and axially supported by a thrust bearing assembly mounted within the turbine housing; andan impeller ri...
