This master’s thesis deals with design of a high speed steam turbine with detachable condensation module and integrated gearbox. As a source of energy is used heat waste, which is a result of the diesel engines function. Important options concerning conception of the turbo set are discussed in the master’s thesis. Subsequently, thermodynamic calculations for each module are done. Part of the thesis is also simplified calculation of the integral gearbox. Construction drawings of all modules and of the complete turbo set with electrical generator were created based on thermodynamic calculation.

The Master's thesis is focused on the quality management in Industrial Turbomachinery, a subsidiary company of Siemens.

There are drawings of sectional views of each unit and there is also a drawing of construction arrangement of steam turbine with a generator.

In the past, steam turbines were mostly used for base load operation. Nowadays, with the increased development of variable renewable technologies, these same steam turbines are withstanding higher cyclic operational regimes with more frequent start-ups and fast changing loads. As such, improving the operational flexibility of installed and future designed steam turbines is a key aspect to be considered by equipment manufacturers. Steam turbine start-up is a phase of particular interest since is considered to be the most intricate of transient operations. During this phase, the machine can potentially be subjected to excessive thermal stresses and axial rubbing due to differential thermal expansion. These two thermal phenomena either consume component lifetime or can lead to machine failure if not carefully controlled. As such, there is a balance to be considered between increasing turbine start-up speed while ensuring the safe operation and life preservation of these machines. In order to improve the transient operation of steam turbines, it becomes important to examine their thermal behavior during start-up operation. To do that, it is important to have tools able to predict the thermal response of the machine. In this thesis work the impact of different aspects and boundary conditions on the results of ST3M, a KTH in-house tool, were investigated with the aim of understanding how large was their impact on the way to capture the thermal behavior of the turbine in terms of metal temperature and differential expansion. A small industrial high pressure turbine was validated against measured data and implemented on a sensitivity study; this analysis showed that the geometrical approximation introduce errors in the results, that the use of empirical Nusselt correlations give similar results to the validated model and that the cavity assumptions have a large impact on the trend of the differential expansion. Lastly, a strategy to validate any other similar turbine to the one of the study case was proposed in order to give a guide to future works in how to validate a model and what are the most influent parameters to take care of.
