An experimental investigation into the impact of moisture content on the flammability of fuels has been undertaken in this work. Two different vegetation types are studied; Molinia grass and moss. The approach followed in this work consisted of developing an appropriate sample preparation procedure to ensured homogeneous drying in a conditioning chamber and the development of an apparatus to support a consistent ignition procedure. The probability of ignition is evaluated as a function of fuel moisture. For Molinia grass, ignition is very likely to occur for a moisture content of less than 75%. For moss, this transition stage revolves around 20% of moisture content. Additionally, drying curves have been drawn for the specific drying conditions (30 ºC and 90% relative humidity), which can provide insight into the rate of drying of organic materials for these given environmental conditions. Finally, a discussion presents the main findings and limitations of this work, while providing insight into possibilities for future research. |
