Biomass boilers
Jelen, Richard ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with biomass boilers. The first part is dedicated to biomass, its distribution, characteristics and potential. The second part describes a combustion process, construction and severance of biomass boilers. The last part of this thesis compares the selected biomass boilers from an economic perspective.

Biomass Boilers
Nahodil, Jiří ; Moskalík, Jiří (referee) ; Baláš, Marek (advisor)
Bachelor’s thesis deals with the use of biomass for heating houses and apartment houses. The first part is dedicated to biomass. Here are mentioned the possibility of energy recovery, treatment and transformation of biomass into a form suitable for burning, its properties and combustion process itself. The second part is devoted to biomass boilers, their separation and description. The last section compares the specific biomass boiler with a boiler to natural gas, particularly from an economic perspective on the acquisition and subsequent operation.

Boilers with medium capacity for biomass combustion of czech and foreign production
Habán, Tomáš ; Kropáč, Jiří (referee) ; Pavlas, Martin (advisor)
The main objective of this work is to focus on biomass as one of the components of renewable energy sources for the production of thermal energy by combustion. The introduction of work maps the current state of biomass used in the Czech Republic. It evaluates options for future uses for biomass and also the size of the potential in the natural conditions of the Czech Republic. It also views this renewable resource from the point of view of energy conception and evaluace the government positron on this issue. Next part deals with the combustion of biomass and with the use of created thermal energy. It ruminate a problem of pollutants and shows values for emission limits results from the legislation. It shows ways of using this thermal energy and the associated production of electrical energy including an overview of the possibilities of its evaluation. The last part of this work describes a comparison between biomass boilers from Czech and foreign producers in the range of rated output 1 to 3 MW. It divides boilers in terms of legislation and shows the obligations and conditions attached to the operators of biomass boilers. It outlines the biggest application of boilers with medium capacity for biomass combustion in the Czech Republic.

The environmental aspects of biomass boilers operation
Slavíček, Martin ; Urban, Lukáš (referee) ; Pavlas, Martin (advisor)
The content of this thesis focuses on the subject of biomass usage for energetic purposes. The introduction deals with the renewable energetic resources and their utilization and utilization of the biomass as a fuel, its division and characteristics. The following part deals with the legislation in the Czech Republic for the machinery used for combustion of biomass and its standards. Examples of different technology used in boilers and generators for biomass is mentioned as well. Then the biomass emissions with their specific values are discussed.

Biomass processing for direct combustion
MAREK, Jakub
The aim of this work was to create an overview of the possibilities for using biomass for energy purposes, and treatment technologies for direct combustion of biomass. Furthermore, it was assessing the energy intensity of production of wood briquettes and compared the amount of energy supplied to the process, the amount of energy gained by burning the fuel. As the data were used to assess the monthly energy consumption for the years 2009 and 2010. The average value of energy supplied to the manufacturing process is 91.9 kWh per tonne of briquettes produced in 2009 and 89.8 kWh/t in 2010. The amount of energy embedded in the production of briquettes, then 15 450.7 MJ per tonne of fuel. When compared with the calorific value of briquettes, then the result of the manufacturing process has an energy recovery fuel.
