Steam Turbine and Compressor Train Performance — online
Can the steam turbine carry the compressor, and by how much?
Yellow cells are inputs; orange cells are choices; blue cells choose the unit. Select or hover over an input to see its help in the box below the toolbar. The sheet is the same as the Excel tool (USD 49) — the Guide, method and references are in the Excel file.
What this steam turbine and compressor train performance calculator does
A steam-turbine-driven compressor train as one system: shaft power the turbine can deliver against what one or two compressor casings need, the margin, and the speed that balances the train.
- Turbine side. IAPWS-IF97 steam, efficiency entered or found from the exhaust temperature, mechanical and gearbox loss, available shaft power.
- Compressor side. Real-gas polytropic head, efficiency and power for one or two casings in series, any gas or mixture of up to 12 components.
- Train balance. Power margin in kW and %, the turbine efficiency that just carries the load, the steam flow needed.
- Speed. Operating against maximum continuous speed with affinity-law scaling, and the speed at which available power balances the load.
- Cost of the efficiency gaps. Turbine and compressors against reference, in extra steam and money per year.
- What-if tables. Steam temperature and pressure, exhaust pressure, suction temperature and train speed.
How it was checked
Every result and message cell of the online tool was compared with the Excel workbook recalculated independently, at the default inputs and at four sets of randomly changed inputs, with the displayed text identical. The method and sources are those of the Excel tool and its Guide.
