Computational Model of KWH Boiler
Koiš, Jiří ; Skála, Zdeněk (referee) ; Lisý, Martin (advisor)
The subject of this thesis is the computational model of existing KWH boiler. There is a short research in the introduction, which deals with combustion heat of considered boiler. The stoichiometric and balance calculations of gasification chamber ZKG are performed first. The Balance calculations are based on the boiler thermal loss calculations, the losses were determined experimentally. The entire calculation is processed in a computational program for purposses of debugging and manipulation with partial calculations. The computational model that is proposed in this thesis provide better boiler proces understandig. The real boiler measurement is performed for evaluation. The next point is the result analyses, that shows potential boiler efficiency improvements.

Steam boiler for burnig mix of wood and sub-bituminous coal(mixing 50/50).35t/h
Chmelíček, Jiří ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
This master´s thesis deals with the constructional and calculation design of the boiler for burning wood and sub-bituminous coal. The work is divided into several parts. First, stoichiometrics calculation and enthalpy calculations 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, the dimensions and individual heating surfaces are proposed. At the end of the calculations are controlling the overall energy balance.
