Kotel na spoluspalování plynů / Boiler for Co-combustion of Gaseous Fuels

Mandelík, Ladislav January 2018 (has links)
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.

Roštový kotel na spalování tříděného odpadu / Grate RDF Boiler

Krolák, Michal January 2018 (has links)
This master's thesis deals with design of steam grade boiler for burning refuse derived fuel with power output of 70 t/h. The assignment contain a requiered steam output parameters and composition of fuel. From this composition of fuel is calculated stoichiometric calculation, the heat loss and the efficiency of boiler. After that follows a design of the boiler with closer design of each of the heating surfaces.

Roštový kotel na spalování biomasy / Grate Biomass Boiler

Michalica, Martin January 2018 (has links)
This thesis deals with the design grate boilers with natural circulation for the combustion of contaminated biomass. The boiler output is output 45 t/h. Produced superheated steam with the output parameters of 440 °C 4,2 at MPa feed water temperature 115 °C. The stoichiometric calculations and the thermal calculation are based on the specified fuel composition. Thanks to this, the basic dimensional design of the boiler and its efficiency are determined. Calculation of this work focuses mainly on thermal calculations and dimensional design of individual heat transfer surfaces. Basic drawing of the boiler is available in the attachment of the thesis.

Paroplynové zařízení se vznětovým spalovacím motorem / Combi -cycle with Diesel Engine and Steam Turbine

Bouše, Richard January 2018 (has links)
This master’s thesis deals with the possibility of increasing efficiency of energy blocks with combustion engines by the combination of the Sabat and Clausius-Rankine cycle into the combined cycle. In the thesis is briefly described the principle of the function of the auxiliary device, which can increase the efficiency of the combustion engine. This device, which consists of a waste heat boiler and two turbine modules, is designed using calculations. Both turbine modules are prepared with drawing documentation and there are described important structural elements. Each key part of the thesis is given by a brief theory, so the basic theory of combustion engines, waste heat boilers and steam turbine are described.

Roštový kotel na spalování RDF / Grate RDF Boiler

Lachman, Jakub January 2019 (has links)
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.

Návrh parního plynového kotle / Design of steam gas boiler

Kuriál, Jakub January 2020 (has links)
This thesis deals with a design of a steam boiler combusting natural gas. It consists of stoichiometric calculation, determination of boiler efficiency, thermal calculations and determining geometric parameters of the boiler and its heat transfer surfaces. The results are verified by the heat balance of the boiler.
