Design of a steam boiler for a new municipal waste incineration plant
Maňák, František ; Křemínský, Pavel (referee) ; Baláš, Marek (advisor)
This diploma thesis describes the issue of energy utilization of waste. The first part is focused on the research of legislative requirements, the description of properties of the municipal waste, and attention is also focused on the comparison of present waste-to-energy technologies used in the Czech Republic. The main focus of the diploma thesis is the design of the steam grate boiler for the new waste incineration plant and related activities, such as stoichiometric calculations, heat balance of the boiler, determination of losses and efficiency of the boiler. Emphasis is then placed on the design and calculation of the combustion chamber and the individual heat exchange surfaces in the other stages of the boiler. This is followed by a check of the heat balance of the boiler and evaluation of the calculation accuracy. The final part consists of evaluation of the risk of chlorine corrosion, the formation of which threatens the boiler thermally processing municipal waste, therefore must not be underestimated.

Grate Biomass Boiler
Kleinová, Martina ; Křemínský, Pavel (referee) ; Lisý, Martin (advisor)
The main content of the thesis is the design of a steam boiler for biomass of smaller outputs of 6 MW. The fuel of the boiler was chosen spruce wood chip by 40% humidity. The parameters of the superheated steam are a temperature of 420 °C and a pressure of 40 bar. The work includes stoichiometric and thermal calculations, which are determined by fuel composition and output steam parameters. In the annex to the thesis, individual heat-exchange surfaces and the dimensional design of the boiler, including the layout, are marked. This work also features calculations of pressure losses on the part of both media.

Support Technologies of Steam Boiler
Uhříček, Michal ; Křemínský, Pavel (referee) ; Lisý, Martin (advisor)
The thesis deals with the layout design of a steam boiler burning RDF and the design of its supporting technologies with regard to design practice. In the thesis are modelled 1st - 4th stroke, followed by the flue gas cleaning, feed tank with pumps, flue gas recirculation routes and air ducts. The boiler is denied by a steel structure with platforms and placed in the boiler room. Based on the designed air, flue gas and feedwater routes, an aerodynamic and hydraulic calculation is performed. Using pressure drop, combustion air fan, flue gas fan and recirculation fan are designed. Based on the hydraulic calculation, the feed pumps are designed.

Steam boiler burning fytomass waste
Plot, Rostislav ; Skála, Zdeněk (advisor)
This thesis deals with the calculation of the boiler on stillage. Nowadays, when there's fossil fuels are just biomass seems adequate compensation. The great advantage of biomass boilers is a small amount of emissions, especially the greenhouse gas CO2. Of a given fuel composition is made thermal calculation and dimensioning of heat transfer surfaces of steam boilers. The resulting calculation must follow the parameters of steam at the outlet from the boiler.

Stean boiler for sub bituminous coal, steam parametres 235 t/h, 14 MPa, 540°C
Horák, Stanislav ; Moskalík, Jiří (referee) ; Baláš, Marek (advisor)
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.

RDF Grate Biomass Boiler
Malíková, Veronika ; Křemínský, Pavel (referee) ; Lisý, Martin (advisor)
The diploma thesis deals with the design of a grate boiler for the combustion of a mixture of RDF and wood chips with the specified output and parameters of superheated steam. The introduction consists of stoichiometric calculations and determination of the thermal efficiency of the boiler. The thesis is devoted to determining the dimensions of the boiler, heat transfer calculations, determining pressure losses, checking the heat balance and chlorine corrosion.

steam boiler for woody biomass 88t/h
Lučko, Martin ; Ing.Milan Ryšavý (referee) ; Skála, Zdeněk (advisor)
The aim of the work is to design a plain wood combustion boiler of 88 t/h output. Fuelling component analysis has been added to the basic boiler parameters. For given fuel is prepared stechiometric calculations. After making the heat balance of boiler is determined the thermal efficiency. For given output of steam parametrs (temparature, pressure, volume) are designed individual convective surfaces and dimensons of the boiler. It is also made drawings.

Boiler for Brown Coal Combustion
Pavlo, Matej ; Hoffman, Pavel (referee) ; Skála, Zdeněk (advisor)
The aim of the master’s thesis is thermal calculation and dimensional design of boiler of 235 t/h which burns brown coal. The work is divided into several parts. In the first part, stoichiometric calculation and the calculations enthalpy of flue gases and air are performed. After calculating the heat balance and loss of the boiler, the boiler efficiency is counted. In the next part, thermal calculation of combustion chamber is calculated. Subsequently, design of the individual heating surfaces is proposed. Finally, the overall heat balance of the boiler is inspected. The calculation is supplemented by drawing of the boiler.
