Plynofikace uhelného kotle 210 t/h; 13,63 MPa; 540 °C / Gasification of coal boiler 210 t/h; 13,63 MPa; 540 °C

Zajíc, Josef January 2013 (has links)
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.

Vytápění objektu zdroji na různé druhy paliv / Heating of the Object with Different Fuels

Ladomérská, Jana January 2015 (has links)
In my final thesis I am processing a proposal for heating and preparing hot water for a restaurant with accommodation. This is a three-storey brick house. It is situated on the territory of the Ústí region. The aim of my work is to propose and to assess the appropriate heat source for this object. In the object I chose heating radiators. The proposal is processed in two variants. In the first variant, I suggest a cascade of condensing boilers using as a source of heat. In the second variant, I suggest a cascade of electrical boilers. Hot water will be prepared in reservoir of warm water. The source of hot water will be the same as the source for heating.

Návrh roštového kotle s přirozenou cirkulací na spalování kontaminovaného dřeva / Design of steam boiler with grate firing burning contaminated wood

Král, Ondřej January 2017 (has links)
The master´s thesis deals with steam boiler design that burns contaminated wood with output 55 tons of steam per hour, steam pressure 4,2 MPa and temperature 423 °C. First two chapters focuses on stoichiometry and calculation of heat losses and boiler efficiency. Great part of thesis constitutes of thermal and dimensional calculations of every heat transfer surface. Some specific boiler parts are described considering special fuel properties. Final chapters contain pressure losses calculation of flue gas and heated medium for pumps and fans design. Drawing is also part of the work which is included as an attachment.

Návrh HRSG kotle / Heat Recovery Steam Generator design

Dlouhá, Kristýna January 2019 (has links)
This master’s thesis deals with the design of a heat recovery steam generator. The introductory part of the thesis is dedicated to waste heat boilers, their division and their utilization in combined cycles gas turbine. In the following chapter, an analysis of the existing combined heat and power plant operation is performed. In the next part of the thesis, the conceptual layout of the new source is designed. Subsequently, the thermal calculation of the boiler is carried out as well as the design of individual heat exchanging surfaces. The sixth chapter deals with the strength calculation of the boiler and the outer piping, chambers and drum are designed here. At the end of the thesis there are described off-design states of the new combined cycle gas turbine.

Návrh vytápění a větrání pro rekonstruovaný rodinný dům / Heating and ventilation in a renovated family home

Nejerál, Michal January 2021 (has links)
The main goal of the diploma thesis is to design a new ventilation and heating system in an old house after its reconstruction. The design also includes consideration of the possibility of using renewable resources. A central heat recovery ventilation systém is designed to ensure ventilation of the building. The heating design is based on two independent heat sources. It is a wood boiler and a gas condensing boiler. After considering renewable sources, a photovoltaic system is designed. The results of individual calculations and drawing documentation of designs are also attached.

Modularní horizontální kotel – HRSG / Modular Horizontal Heat Recovery Steam Generator

Primes, Alois January 2021 (has links)
This thesis deals with the design of a Heat Recovery Steam Generator (HRSG). Theintroductory part is devoted to a brief description of the boiler, the specified parametersand the compilation of the temperature profile. The main computational part of thiswork is divided into 6 parts. The first contains preparatory calculations, including thecalculation of boiler eiciency. In the second part, a flue gas duct is designed. This isfollowed by a thermal calculation of the boiler for all heat exchange surfaces. The last 3parts deal with the design of the drum, piping and the loss of boiler draft calculation.
