Energy evaluation of forest residues originated from pine in Galicia.
Pine residues originated from cuts and forestry tasks were studied with the main objective of using them as an alternative source of energy. Calorific values were measured using a static bomb calorimeter in an oxygen atmosphere. From these measurements a value of 7500 kJkg(-1) for the mean lower heating value of these kind of residues was found. A rational and sustainable exploitation of the calorific energy contained in these residues can yield a gross benefit of 2.8 x 10(8) per year through its transformation in electric energy. The study was made along one year, using samples collected in different previously characterized zones. Some other parameters such as: elementary composition, heavy metal content, flammability, and bioclimatic properties were also determined.
