Utilization of Waste Heat from Heating Plant Spitalka
Hromádka, Martin ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This master’s thesis deals with utilization of waste heat from heating plant Spitalka. The aim of the thesis is to explain the general principle of the operation of the heating plants, respectively the heating circuit, then to describe the operation of heating plant Spitalka and to try to identify possible sources of waste heat. Other goals are to make the calculation of waste heat and to make the proposal for its utilization. The final aim of the thesis was to design technological device for utilization of waste heat and to carry out economic evaluation. The master’s thesis describes the principle of functioning of the heating circuit. It explains the issue of combined heat and power production, the principle of functioning of the main technological elements, but also the ecology of operation or distribution of heat through the district heating. Then there is a description of the heating plant Spitalka. The thesis also deals with the water treatment and the description of the technological circuit from the beginning to the distribution to the customer. Next, the waste heat source is identified as water in a closed cooling circuit. The amount of this heat energy is calculated and suggestions for its possible utilization are made. As an application, there are selected two systems, heating and domestic hot water heating. The heating is made by heat pump. Based on the calculations, a heating system using two heat pumps in a bivalent way of connection was designed. In conclusion, the results of the design of the heating system are summarized and an economic evaluation is carried out.

Power Plant Units Cooperation - Optimization of Operating Parameters
Hromádka, Martin ; Wasserbauer, Vojtěch (referee) ; Mastný, Petr (advisor)
This bachelor’s thesis aims to describe the principle of operation of thermal power plant as well as to describe the issues related to increasing the efficiency of production units. Another task was to create a mathematical model of cooperation of power plant units. The thesis also deals with the fundamental issues of power distribution as well as deals with the functioning of the electricity system in Czech republic. In this thesis there are also calculated two sample examples of two parallel cooperated units. In the first example, the optimized electric power is not outside of the control range but in the second, the optimized electric power is outside of the range. So there are two types of the calculations. As a part of the thesis there was made a mathematical model. The mathematical model based on the specified demand load in the network optimizes the eclectic power of three cooperating parallel units. This should lead to the fact that the operating costs will be minimized. In the model there is also a complete calculation of specific consumption and thermal efficiency. The reader of the thesis is able to do these calculations in five possible options.
