Backpressure Steam Turbine

The theme of the master’s thesis is to design a 60 MW single-casing steam turbine for the two-stage district water heating. The turbine is designed for cogeneration cycle, has four uncontrolled extractions and the outlet down to the heater. First, there is the thermodynamic calculation of the turbine operation with 100 % steam mass flow. Further, the detailed design of flow part with the strength calculation of blades and diaphragms is drawn. By the end of the thesis, the required operations are compared and corresponding heat balancing diagrams are listed. The thesis also includes a turbine longitudinal section
