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 RDF Boiler
Lachman, Jakub ; Šilhavý, Karel (referee) ; Lisý, Martin (advisor)
The master’s thesis deals with the design of a boiler for RDF combustion, based on the required power output and superheated steam parameters. The first part of the thesis focuses on combustion calculations. Boiler efficiency is also calculated in this chapter, using the heat balance efficiency method. The main part of the thesis consists of dimensional design and heat transfer calculations. The precision of the calculations is checked at the end of the thesis along with the chlorine corrosion, which is considered because of the higher amount of chlorine in the fuel. The thesis comes with a basic schematic of the designed boiler.
