This diploma thesis is focused on comparison of results from simulations programs ProMax and PRO/II. Both simulation models were based on a sour water stripping unit according to a project of CBI Lummus s.r.o. The thesis also includes a theroretical part deals with technology of sour water stripping.

This master’s thesis is dealing with design of steam boiler for wood chips. Wood chips are considered as biomass and so the steam boiler is considerate to enviroment. Main purpose of this work is calculation of size and number of water/steam heating surfaces so the boiler can produce steam with required parametres of temperature, pressure and amount.

This Thesis deals with thermal control calculation of the existing John Thomson steam boilers burning heating mazut and subsequent thermal conversion to natural gas. The main parts of the calculation are as follows: stoichiometry, thermal balance, conversion of the combustion chamber and heating area.

The aim of this thesis is to design the heating system for the house, including the design and calculating the required quantity of heat for hot water. The specified heat sources are the heat pump air to water and solid fuel boiler. The task was to design the heating system to the fastest possible return on investment. The initial investment in a heat pump is high so it is necessary to design the heating system as efficiently as possible. The thesis contains a complete project of calculating heat loss of the building, the design of heating surfaces and their heat-technical calculation. There is included the design of the pipe system, the calculation of pressure loss and its regulation. The thesis also includes design of safety equipment, temperature regulation and drawings. On the basis of calculated data was processed economic assessment, which determines the return on investment to the heat pump. Compared to the gas condensing boiler the return on investment will ideally be after five years.

This diploma thesis describes the detailed design of heating and hot water heating for a family quest-house. At first the reader is introduced to the designed building, its design and construction elements. The thesis presents the calculation procedure and design of the heating system. This consists of designing radiators, the heat source, the circulating pumps, regulations of the heating system and the design of its security elements. The thesis also describes the design of the heat exchanger for hot water and security. In conclusion, an evaluation of operating costs with the recommended solution for their reduction. The thesis also includes drawing documentation of structural drawings, heating and unrolled schema that is mentioned in the attachment.

This Diploma thesis describes design of the computational model of Uehara power cycle, with ammonia-water mixture used as working fluid. First part is dedicated to issue of determination working mixture thermodynamic properties, which are essential for computational model design. The second part of this thesis describes the methodology of computing power cycle by system matrix solving method. For purposes of methodology testing, model of Kalina power cycle was also created. Computational models of Uehara and Kalina cycles are designed in Excel and are an integral part of this thesis. Text part also includes a description of their user interface, calculation algorithm and detailed description of the design methodology.

Diploma thesis deals with change of heating source for a block of flats with aim to reduce heating costs. Thesis contains calculations of energy requirements of house, including requirements for heating and domestic hot water preparation. Several ways of heating by a heat pump were designed based on the calculated values. Each variant of the designed heating system is compared with current operational costs. Possible cost economies and maximum value of investment costs of the heating system were assessed

The first part of this thesis is focused on water wells and their classification. A big part of this thesis is an essay on groundwater. This thesis also examines the various technical parts of drilled wells and dug wells. The design of pump is discussed briefly. The second part of this thesis is focused on objective and financial complexity of proposed solutions.

Rostoucí světová poptávka po méně efektivních zdrojích energie vede ke zvýšení zájmu o kogenerační technologie v sektoru domácností. Pomocí této technologie lze významně snižovat množství znečišťujících látek emitovaných při výrobě elektřiny a tepla pro domácnosti. Kogenerační systémy v sektoru domácností nabízí možnost produkce jak užitného tepla a elektřiny z jednoho zdroje paliva, např. motorové nafty či zemního plynu. Tato práce se zaměřuje na analýzu možností užití kogeneračních a tri-generačních technologií ke zlepšení efektivity využití primárního zdroje energie, zejména v zemích severní Afriky. První část práce se orientuje na obecné definice v oblasti elektroenergetiky, aktuální i budoucí výhled energetické bilance v Libyi. Následující kapitoly se věnují kogeneračním a tri-generačních systémům, jejich charakteristikám se zaměřením na technické parametry, výhodám a nevýhodám těchto systémů a jejich dalšímu rozvoji. Hlavní část práce se zabývá problematikou spotřeby typických rodinných domů ve třech nejdůležitějších městech Libye. Dále předkládá citlivostní analýzu, která je zaměřená na výpočet množství energie vyžadované k pokrytí energetických potřeb typického domu (vytápění, ohřev vody a klimatizace) a porovnání naplnění těchto potřeb při uvažování technických a ekonomických hledisek. Výsledky práce budou využity pro tvorbu pokladů pro Libyjské energetické úřady.

This work deals with design and implementation of simple demonstration aplication for simulation of a water flow on irregular terrain. The work examines essential building blocks of the simulation. It also suggests approaches that can be used to optimize and/or extend used method.
