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.

Steam boiler for spruce bark burning-18t/h
Dračka, Lukáš ; Heinze, Bedřich (referee) ; Skála, Zdeněk (advisor)
To design a grate boiler with a natural circulation for burning of a pine bark with an output 18t/h is a primary objective of this dissertation. Individual parts of a boiler and it´s heat transfering surfaces were calculated after the working out of stoichiometric calculations from given element analysis of fuel. All computations have to fulfill several parameters: boliler output, temperature and pressure of an overheated steam.

Steam boiler with grate firing burning mix coal and wood (mixing ratio 30/70-wood)
Dvořák, Aleš ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
This diploma work attends to presentation of steam grid boiler for wood and brown coal burning in scale (30/70-wood) in load 60t/h, with parametres of outgoing vapour p=7MPa, t=490°C. The work is splitted to several chapters. At the beginning I’m going to make stechiometric calculation and entalpic calculations of air and compustion gas. After that I’m going to calculate heat balance, losses of boiler and set heat efficiency of boiler. Then I’m going to suggest combustion chamber of boiler and make heat calculation. After suggestion of combustion chamber I’m going to set proportions of pulls and heat-delivery surface. In last chapter I’m giong to check heat balance. Inclosure of my work contains drawing documentation of steam 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.

Steam boiler for wood burning 40t/h
Mach, Ondřej ; Křemínský, pavel (referee) ; Skála, Zdeněk (advisor)
The purpose of this Diploma Thesis is the construction design of the steam-boiler for the combustion of biomass – wood pellets. For the specified parameters have been defined stoichiometric calculations and calculations enthalpy burnt gas. In sequence, there is designed and solved the configuraion of the steam-boiler, so that the result design and the number of the heat-delivery surfaces can be determined, in dependence on the required inlet parametres of the air and outlet parametresof the water vapour. These parametres mean the amount, the temparature and the pressure. The aim of the thesis is to make a design of the steam.boiler burning biomass according to the set parametres. This very ecological fuel can really substitute the fossil fuel and friendly respect the environment.
