This is the presentation of the first part of our project. Which shows the potential recourses that have the forestry sector in the region, for using as energy vector TECHNICAL SUMMARY THE COMPLETE PROJECT First par • We will carry out a detailed analysis the residues of a forest harvest in islands of Delta of Parana River. The different residues of woody characteristics will be classified. • • The woody surpluses will be quantified both the forest harvest as and pruning in plantations of willows and poplars. • The form of manipulation will be studied, loads and transport up to the place of treatment of woody residues to be use as fuel. Second part The heating power of the woody residues will be measured in different times of the year. • • Collection of the woody residues and its preparation will be transformed into gas. • An equipment to generate gas from woody residues will be designed and developed. • The generated gas will be used to stimulate an engine of internal combustion to which an electrical generator. (Small energetic decentralised generator). The engine and the generator are of national manufacture in series, which will have to be adapted for its functioning. This system will have a power of generation of approximately 3kVA to 5kVA in the research beginning, what means a capacity of nourishment with electric power that will allow to satisfy demands in isolated zones, turning the technological transference into a small energetic decentralised mobile generator. An environmental analysis of emission of carbon, product of the burning of woody material for the gas production will also be carried out. The woody material will be chosen of two or more samples extracted from a hectare of poplars and willows that turn out to be representative of the Delta surfaces forestry. 1.- General considerations 1.1.- Weather It is possible to consider the climate of the Delta region as moderate (tepid). The warmest month (January) gives an average of temperature of 22,4ºC and the freshest month (July) of 9ºC. The rainfall, approximately 960 mm per year, is distributed uniformly enough among the months, but the number of rainy days is limited since most of the rainfall takes place during intense downpours. The average of fogginess is low and the solar light is abundant. Due to the proximity to the Atlantic Ocean and the Rio de la Plata and of the great number of rivers and marshes in the same Delta, the relative dampness is raised on all the stations of the year and gives an average of approximately 75 %. The winds are generally light.
2.-Description of the place of the extraction of the material of this study in particular and of the plantations in general 2.1 Location of the place of the evaluation The activity was centred on the establishment the OASIS of the company SAVITAR, placed in Islam’s zone of Campana district, on the Route 12, Km 103 between the bridges of the rivers Parana de las Palmas and Parana Guazu. This establishment was chosen for its accessible location by firm land, for typical conditions as for the forest production, the establishments of the zone and for especially the attitude of the personnel of the company to a research of this type. The fields were flooded because of being in a closed dock, that received more than 400mm of rain during the
