Gasification of coal boiler 210 t/h; 13,63 MPa; 540 °C
Zajíc, Josef ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This thesis aims to gas installation of the coal boiler and its thermal recount. In the first part, there is implemented calculation of the combusting chamber. After that follows the recalculation of heat exchange surfaces and proposal tube air heater, which will replace the existing air heater Ljungström. The emphasis is placed on the preservation of the exsiting steam parametrs and keeps emission limit of NOx.

Steam boiler for waste burning 40t/h
Fejfuša, Martin ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
This thesis deals with a project of steam boiler to combustion of refused-derived fuel. With respect of required fuel and output parameters of the steam was worked out stoichiometry, energy loss and boiler efficiency, heat flows was allocate to individual heat exchange surfaces. The heat exchange surfaces was calculate and project in detail.

Design of steam boiler in waste to energy plant
Reiskup, Matěj ; Tomáš, Weigner (referee) ; Skála, Zdeněk (advisor)
The thesis deals with the design of the boiler to combustion of mixed communal waste. The introductory chapters present introduction of the problem, short explanation about fuel of the boiler and speciality of the boiler to combustion of mixed communal waste. The main part is the heat calculation of the boiler, which consists of stoichiometry of the combustion, heat losses, then disposition of heat performances to individual exchange surfaces. In the end is summary of calculation and knowledge consequent of the calculation.

Boiler for Co-combustion of Gaseous Fuels
Mandelík, Ladislav ; Křemínský, Pavel (referee) ; Lisý, Martin (advisor)
The topic of this diploma thesis is to design the co-firing of blast furnace gas and coke-oven gas. First, the stoichiometric calculation for the gas mixture was made. It is followed with the determination of basic measures of heating surfaces and with their thermal calculation. The part of the work is also the drawing documentation of the boiler.

Steam boiler with wood grate firing
Jakeš, Pavel ; Skála, Zdeněk (advisor)
This diploma thesis deals with proposal of the steam boiler on combustion uncontaminated wood. For the specified parameters have been implemented stoichiometric calculations and calculations enthalpy burnt gas. In the next part have been dealt with heat balance of the boiler, the efficiency of the boiler, design of the combustion chamber and calculation of particular rating surfaces. The output parametres are temperature, pressure and the amount of steam.

Steam boiler with natural cirkulation for wood cheaps burning
Vaculík, Jaroslav ; Kohout, Přemysl (referee) ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
The purpose of this Diploma Thesis is the construction design of the steam boiler with natural circulation for the combustion of wood biomass according to the specified parameters. It is the boiler with the power of 12 tons per hour of superheated vapor output parameters of 3,3 Mpa at a temperature of 400 °C and a temperature of feed water 105 °C. For the specified parameters I first calculated the stoichiometric calculations, boiler efficiency, and followed by using geometrical parameters of the blocks and thermal calculations set design and the number of heat transfer surfaces, depending on the input parameters of the air and water and output parameters of vapor. The work also includes drawings of the boiler.

Grate Boiler for Wood Chips Combustion
Kozák, Tomáš ; Kohout, Přemysl (referee) ; Lisý, Martin (advisor)
The thesis is dedicated to the design of the steam boiler which burns wood chips, with a natural circulation of the water. It is a grate boiler, which produces 20 t/h of the steam. The output parameters of the steam are 420 °C and 5 MPa. The feedwater temperature is 125 ° C .The thesis gradually deals with stoichiometric calculations and determines the efficiency of the boiler. Then it describes the design of the fireplace and thermal calculations of each heat transfer surfaces. The appendix includes drawings of the boiler.
