Procesy a fungování bioplynové stanice
ŘEZNÍK, Luboš
It is necessary to look for options of more rational use of energy and find a way how to make the most of renewable energy. As we can see, there has been a huge increase in biogas stations in Czech Republic since 2010. The most used in our country are agricultural biogas stations. The feedstock into a biogas station is mainly manure, liquid manure, crop residues, corn silage, biomass from grasslands, energy crops etc. This bachelor thesis summarizes the history and the basic characteristics of biomass where we are interested in the use of biomass for energy purposes. The thesis also includes the explanation of the history of production and use of biogas in the Czech Republic. In the practical part I analyzed and explained the function of the biogas station Klučenice in the local agricultural establishment. In the thesis is explained how the biogas station was projected. Then I focused in detail on technical operations units, where I made comprehensive evaluations. I split the created operating units into 7 groups, subsequently described in detail and added tables and graphs. In the second phase of practical part I typified and described the annual consumption of vegetal and animal ingredients. Then I made a list of the total electricity production in the biogas station Klučenice and assessed its economic strength.
Using of digestate of agricultural biogas stations
VERNER, Dušan
This work deals with problems of agricultural biogas stations with the focus on using of final product of anaerobic fermentation, digestate, on agricultural soil. It evaluates its fertilizing effect in comparison to industrial fertilizers. The results showed that the fertilizing effect can improve economy of growing plants, however it depends on quality of digestate, constitution of base input material and technology of processing. It is not possible to use digestate anytime, it depends on growing crops and its technology. Nevertheless digestate as a final product of anaerobic fermentation is an interesting fertilizer.
