Steam Boiler with grate firing RDF 70t/h, 4MPa, 400°C
Mokriš, Lukáš ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
The goal of this Master’s Thesis is to design a refuse derived fuel (RDF) fired steam boiler with 70 t/h processing ability. The assignment consists of requested output parameters of overheated steam and analysis of fuel components. This analysis was used for stoichiometric calculation of fuel. Furthermore, heat balance of the boiler was calculated, from which was determined the heat loss and the efficiency of the boiler. Individual designs and calculations of heating surfaces and boiler dimensions were carried out from requested output parameters.

Steam boiler for straw 10t/h, 320°C
Truhlář, Marek ; Kól, Přemysl (referee) ; Skála, Zdeněk (advisor)
The aim of this thesis is design a grate steam boiler for burning straw with an output of 10 tons of steam per hour. The produceds team has parameters 320 °C, 3,2 MPa. For a given fuel (fytomass) is calculated stoichiometric calculation. The following is the calculation of the heat balance of the boiler including the determinativ of thermal efficiency. The fuel used, the required parameters of steam and feed water temperature are designed individual convective surfaces and dimensions of the boiler. The boiler design includes drawings.

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 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.
