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.

Possible utilization of grass material
 KOBERNA, Daniel
The objective if this degree work is creating a survey of possible uses of surplus grass material which is caused by animal farming reduction and by bringing the ground in less fertile areas of our country to a standstill. In the work possible uses of the grass are described, especially its use in the energy industry as a fuel source for the production of heat and biogas. Classical usage of the grass material as a food source for livestock or for the production of compost is described here as well. Examples are shown there of energy kinds of grass, which seems to be a promising renewable resource of biomass for favourable economic results. The harvest of the grass material and its consequent prossesing is done by production lines, that is why a survey of such lines and their economic figures connected with the operation of these machines is also included in this work. The economic part of this work contains many formulae that can be used for counting out all the costs connected with the operation of the grass harvest machine and for evaluating the effectiveness of the return on investment into this machine
