The point of this thesis is a waste gas condensator for 200kW woodchips burning boiler. In the first part of the thesis types of heat exchangers are introduced. Condensation is introduced. Further all necessary equations and relations for vertical shall and tube heat exchanger are specified. Following those relations waste gas condensator is designed. Situation under different input conditions is talked over in the end.

The aim of the master’s thesis is to design a condensing steam turbine based on given inputs. Firstly, a design and computation of heat balance is made, followed by thermodynamic calculation of steam turbine channel and a design of compensatory piston of axial forces. Last part of the thesis consists of a review of a change of cooling water temperature in condensator on last turbine stages. The structural drawing of longitudinal section of turbine is included as well.
