Studium technologií zpracování biodegradabilních odpadů z trvalých porostů pro energetické účely
Michálek, Milan
The dissertation thesis entitled "Study of technologies for processing biodegradable waste from permanent crops for energy purposes" is about the use of waste wood material generated after the pruning of crops (vineyards and orchards). The processing of waste biomass from these crops can be used machinery, such as shredders, shredders with reservoir and shredders. In this theses were carried out a series of monitoring of times and computing performance of different machine sets in different conditions. Individual monitoring varied by the use of machinery, cultivation of the variety series length, slope of terrain, spacing, etc. The recalculated performance then ranges from 0,41 to 0,77 hectares per hour. From the time measurements and calculations of costs were for each variant of processing of the vine cane determined values of costs from 880 to 1,357 CZK per ton of wood chips and from 941 to 1,184 CZK per tonne of vine cane compressed into the bales. For the processing of waste wood from orchards, the resulting values were 909--1742 per ton of wood chips and 1128--1505 per tonne of bales. As the most economically advantageous technological progress of processing the vince cane seems to be shredding to the trailer attached behind the shredder. For this method, the resulting cost of wood chips range from 880 CZK per tonne. The same technological process is also proven in the orchards, where the resulting costs per ton of wood chips is 909 CZK. These results confirm that testing technologies provide a competitive bioenergy products. Economic evaluation of monitored technologies depending on the deployment shows that these technologies can be implemented effectively in enterprises with horticultural areas over 45 ha. This area corresponds to medium and large wine-growing and fruit growing enterprise
