Abstract
GAST project stands for 'Experiences in biomass GAsification in South-Tyrol: energy and environmental assessment' and has raised an opportunity to monitor and analyze small scale biomass gasifiers in the region of South Tyrol (Italy). Free University of Bozen-Bolzano, in collaboration with other partner research institutes, is implementing this project in order to assess a test methodology for small scale gasification systems. In the framework of this project, a monitoring campaign has been carried out on three different gasification technologies for combined heat and power (i.e., CHP) generation. The monitoring has been performed in agreement with the test methodology proposed by the "Raccomandazione CTI 13" standard, i.e., a guideline about the contracting and commissioning of gasification systems recently published by the Italian Thermotechnical Committee Energy & Environment (CTI). The present work aims to assess the test methodology that should be utilized to evaluate both the energetic performance and the environmental impact of a small scale CHP gasification system. In addition, the main technical issues arisen from the measurement campaign and from the lab analysis have been discussed.
