The aim of the work is to design a brown coal combustion boiler of 235 t/h output. The work is divided into several parts. First, stechiometric calculations and calculations enthalpy of air and flue gas are performed. It is calculated heat balance of the boiler, the boiler losses and the thermal efficiency of the boiler is determined. After designing the combustion chamber thermal calculation is made. Then, individual heating surfaces are proposed and at the end of the calculations are controlling the overall energy balance of the boiler. For calculation was design documentation added.

Návrh opatření pro plnění emisních limitů u kotle bloku 210 MW / The proposal of measurements to fulfill emission limits for boiler of power unit 210 MWSmokoň, Pavol January 2014 (has links)
This master‘s thesis deals with denitrification of brown coal-fired boiler of electric power plant. First chapters describe technical characteristics of the boiler and possible measurements which would lead to lowering NOx emissions. In order for boiler to meet emission standards valid from 1.1.2016 flue gas treatment by selective catalytic reduction is proposed. Main part of the thesis is thermal calculation of the boiler with modifications necessary in order to apply SCR. The aim of calculation is to determine flue gas exit temperature and temperature at catalyst area in order to assess the suitability of proposed modifications.

Čištění bioplynu pomocí metody PSA (adsorpce za měnícího se tlaku) / Cleaning of biogas by the PSA (pressure swing adsorption)Navrátil, Petr January 2014 (has links)
The topic of this master thesis is upgrading of biogas. As a mixture of gases produced during anaerobic digestion, contains methane which is highly energy valuable gas. But also other substances that we want to remove. We will present the motivation for upgrading biogas and the possibility of separation, generally the pressure swing adsorption method. The key parameter of this technique is the choice of a suitable adsorbent. This is possible based on the knowledge of adsorption processes, therefore, is also described below. The objective of this thesis is to determine the parameters of the pressure swing adsorption metod. To do this it is necessary to determine the adsorption capacity of the adsorbent, measure breakthrough curves of carbon dioxide and methane, and determine the pressure drop of solid bed, etc. As a result we can finally make a balance and evaluate the applicability in practice.

Návrh mlýnského okruhu kotle PK 4S v Teplárně Košice / The Proposal of Coal Mill system for Boiler PK 4SKubínek, Martin January 2015 (has links)
The aim of this thesis is the proposal of a coal mill system and a combustion chamber for the boiler PK 4S situated in Košice CHP station with regard to transition to the new fuel. This proposal is focused on the elimination of NOx emissions. The calculation is based on required parameters of the boiler and declared characteristic of the new fuel. The proposal of the coal mill system includes three roller mills working in closed circuit with direct blowing. One of the mills serves as a reserve in case of failure. Dimensions of the dry bottom combustion chamber are proposed considering the applied primary measures to reduce NOx emissions so that the temperature at the end of the furnace would not be higher than maximal allowed temperature 1200 °C.

Roštový kotel na spalování uhlí a nebo dřevní biomasy o parametrech 200 t / h 9,3 MPa, 520°C / Steam boiler with grate firing , burning coal or wood biomas 200 t/ h, 9,3 MPa 520°CČech, Jaroslav January 2015 (has links)
The aim of the work is the design of a grate boiler of 200 t . h-1 output, which will burn brown coal or wood chips. The work is divided into several parts. First, stoichiometric calculation and the calculations enthalpy of flue gases and air are performed. After calculating the heat balance and loss of the boiler was counted boiler efficiency. The design of individual heating surfaces is proposed and at the end are controlled the overall heat balance of the boiler. The calculation is supplemented by drawings.

Roštový kotel na spalování uhlí a dřevní biomasy / Grate Boiler for Biomass and Coal Co-combustionBaláži, Martin January 2016 (has links)
This thesis solves a design of a grate boiler burning wood chips or brown coal with a heat output of 160 MW. Stoichiometry flue gas is calculated according to the specified composition of each fuel. The dimensions of the individual heating surfaces are primarily calculated for burning wood chips and subsequently checked for the combustion of brown coal. Design of the boiler is completed by checking the overall heat output. Boiler design is accompanied by drawing documentation.

Sledování pesticidních látek ve zdroji úpravny vody Hrdibořice a možnost jejich odstranění / Monitoring of pesticides in source of water treatment Hrdibořice and possibility of their removalBouchalová, Zuzana January 2017 (has links)
The thesis discusses possible ways to reduce or completely eliminate pesticide compounds from drinking water that are produced at a water treatment plant Hrdibořice. The work is divided into theoretical and practical parts. The theoretical part lists kinds of pesticides that occur in water, how they are reduced or eliminated. Furthermore, this section describes the existing water treatment technologies at the Central Committee Hrdibořice, including water sources. In the practical part, pilot tests on two types of filters models with filtering bed of granular activated carbon (hereinafter GAU) were carried out. On the basis of information obtained from the literature and on findings from the pilot tests, designs of technological equipment for pesticide removal from drinking water at water treatment Hrdiborice were carried out. Next, cost estimates for the proposed variant solutions including operating costs were suggested.
