Utilization of absorption systems in the heating systems
Vidlák, David ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
Main goal of this work is familiarization with basic features of absorption heat pumps and it’s growing importance on the market. In the first part of the work there is a research for clarifying facts associated with such pumps. In the introduction there are descriptions of basic information from the field of heating industry and its connections to our systems. Next there is a brief analysis of price changes in electricity and heat in the last five years. Main part of the analytical section is a description of the used absorption system. Second part of the work is focused on the calculation of the absorption system itself. First there is calculated internal and external part of the device according to the parameters from GE Power s.r.o. After this step there are parametric studies based on changes of key parameters of the default device for a demonstration of the behavior of a heating pump. In the end of the work there is a integration of the unit into the heating cycle for variations including flue gas condenser and using a cooling water from the turbine condenser.

Calculation of the heat balance of latent heat utilization of flue gases by means of a condenser
Toman, Filip ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
Thesis is focused on calculation of the condenser of flue gas, which is created by burning of natural gas. In the first part is theoretical overview of equations describing film condensation and physical properties of the flue gas. The second part deals with practical thermal calculation of the specified condenser. In third part parametric study is done in which a tempature of cooling water at inlet and the coefficient of excess air are changed. The last part of the thesis is dedicated to geometric design of the flue gas condenser whose required power is 8 MW.

Design of heat exchanger for heating and humidification of combustion air
Pollach, Ondřej ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
The diploma thesis‘ goal is to design shell and tube combustion air preheater for biomass boiler. The diploma thesis also includes the research of the effect of flue gas condensation on boilers power increase. The first part of the diploma thesis is theoretical introduction about types of air preheaters, options of air moisturing and effect of flue gas condensation on boiler. Following part describes the thermal calculations and construction design of air preheater as well as the condensing flue gas power increase and power increase due to humidification of combustion air.
