Steam Turbine for fossil power plant - MP LP casing
Třináctý, Jan ; Weber, Norbert (referee) ; Fiedler, Jan (advisor)
This thesis describes the design of a condensing steam turbine with reheating for fossil power plant. The turbine is a double parts. The first casing is formed by a simple HP casing. The second casing is combined MP-LP casing with axial outlet of steam into the water-cooled condenser. Feedwater regeneration system consists of two high-pressure heaters, the four low-pressure heaters and feed tank. In thesis is includes the calculation of heat balance and the draft of flow channel of HP and MP-LP casing. Next is a detailed calculation of MP-LP casing with includes calculation of flowing part, selection of blade´s profiles and its stress control. Rotor MP-LP casing is checked for torsion and computed size of the critical speed. Clutch is ispected by security check and draft radial bearings. Stress control casing is carried out according to the theory of thick shells. Work includes flow scheme for 100% and 75% performance. In the end is comparing the efficiency of the individual casing of the turbine with the work 3b together with the specific heat consumption. Work includes a longitudinal section of the MP-LP casing. This thesis has been developed in cooperation Škoda Power, Doosan.

Condensing Steam Turbine with superheating
Urbánek, Martin ; Weber, Norbert (referee) ; Weber, Norbert (referee) ; Fiedler, Jan (advisor)
The thesis is focused on designing of condensing steam turbine with reheating for combustion of biomass. The turbine is developed to be tandem compound-regenerative with five uncontrolled extraction points. Optimization of reheating pressure is made in the turbine's cycle. The turbine outlet is constructed to lead down to the water cooled condenser. Thesis includes the calculation of heat cycle with the draft of flow channel of high pressure and middle-low pressure turbine. Detailed calculation of middle-low pressure turbine, including stress-strength analysis, is performed. The thesis provides an evaluation of flow scheme of 100 % and 75 % of generator’s power output and the drawing of middle-low pressure turbine in longitudinal section.
