Abstract
In the current context of climate change, a special place is occupied by the field of energy plants. One of the renewable sources providing the biomass necessary for the generation of bioenergy, widely used in the last decades in the EU countries is the Miscanthus culture, which by capitalisation provides a series of economic benefits, but especially in terms of environment. This can be used for the production of electricity and/or thermal energy both in large power plants (30 MW +), which use thousands of tons of biomass annually, and in small domestic systems that use several tons, during the winter months. By using the Miscanthus in the combustion process, the carbon dioxide emissions are reduced and the methane emissions from the deposits are eliminated. In the case of applying the technology for Miscanthus culture direct harvesting (culture of perennial plants, over 2 m high, and high density), the technological process consists of cutting, chopping and loading in the means of transport of the harvested material. The paper presents the technological process of direct harvesting and analysis of the results obtained, achieved with the help of the trailed forage harvester CTF.
Highlights
In order to reduce the global warming due to the greenhouse gas emissions concentrated in the terrestrial atmosphere, a lower use of energy, especially the one derived from fossil fuels, is intended
The rapid reduction of energy resources derived from fossil fuels in parallel with the continuous increase of energy needs, requires increasing research efforts for the development of new sources of renewable energy [1]
Biomass can be produced by the special cultivation of plants for the generation of electricity, plants which are called “energy plants”
Summary
In order to reduce the global warming due to the greenhouse gas emissions concentrated in the terrestrial atmosphere, a lower use of energy, especially the one derived from fossil fuels, is intended. In the case of applying the technology for Miscanthus culture (culture of perennial plants with a height of over 2 m, and high density) direct harvesting, the technological process consists of cutting, chopping and loading in the means of transport of the harvested material. Because the Miscanthus stalks, harvested with the combine, are used as fuel in the burners of the thermal power plants, without being subjected to further processing, it is recommended that the chopped matter size be 10 ... The main objective of the experimental research was to verify the technological efficiency of the chopping drums with straight knives placed in a cascade in the process of harvesting the Miscanthus stems
