Steam turbine for a waste incinerator
Balažovič, Lukáš ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
The diploma thesis contains the design and comparison of two steam turbines for a waste-to-energy plant. One turbine is single shaft and the second is divided into two parts, high speed and low speed, on two separate shafts. A thermodynamic calculation of the blading of both variants is performed and subsequently evaluated. Furthermore, the axial and radial forces in the turbine are calculated, based on which suitable bearings are selected. At the end of the thesis, a simplified economic comparison is made for the winter operation when the steam goes to the central heating system. In the case of the single shaft turbine, about 10 % of the steam is thwarted in the low pressure section of the turbine, while in the second variant all the steam goes to the heat exchanger. Based on the design, three conceptual drawings are drawn.
