Chapter 2 Feedstock characterization The characteristics of the biomass samples have been found by means of the measurement of:
moisture content of the samples (as received and after the stabilization process); ash content (of the stabilized samples); HHV and LHV high heating value; C,H,N,S content with the aim of an elemental analysis; Mass loss against temperature by means of a thermogravimetric analysis;
2.1 Samples description 2.1.1 Material employed as reference for the gasification tests: high quality woodchip An high quality wood chip sample has been considered as reference for the gasification tests. The high quality wood chips samples to be used in the gasification plant have been collected from the company Furlan Luigi & Figli placed in Mezzocorona (TN). At the moment of the collection, woodchip where collected in piles placed inside a closed warehouse. A sample of this material is shown in Fig.2.
