Abstract
Industrial pellets made from blends of shrubs and cork residues were made in lab facilities and tested under the European standards for solid biofuels (ENPlus). The pellets were carbonized in nitrogen atmospheres at 800 °C, being subsequently cut into smaller and more uniform particles. Three different lengths, 4-5, 7-8 and 11-12 mm were used. The mean diameter of the char pellets was determined using the Image J open source image processing program software. The combustion tests were carried out in a fluidized bed reactor at two different temperatures, 700 and 900 °C. Using a simple combustion model [1] kinetic and diffusive data, namely kc and Sh values, were obtained.
