Firebrands are a major ignition source in large scale wildland and Wildland-Urban Interface (WUI) fires. Limited studies have been reported regarding firebrand generation. It was hypothesized that firebrand production characteristics can be described by using thermal and combustion properties and geometry factors of the fuel, and the ember production characteristics will be functions of these controlling factors. As a first step to test this hypothesis, this thesis measured the basic pyrolysis and combustion properties (at small scale) of selected structural fuels (construction materials) under a range of heating rates, radiant heat flux (HF) levels, and moisture content (MC) levels. The following seven commercially available structural fuels were selected for the study: one Southern Yellow Pine (SYP) framing lumber product, one Spruce-Pine-Fir (SPF) framing lumber product, three Oriented Strand Board (OSB) products [two sheathing types (OSB-PF and OSB-H) and one siding type (OSB-siding)], one Plywood sheathing product (CDX grade), and one Hardboard (HB) siding product. The pyrolysis properties of the selected structural fuels were measured by using the Thermogravimetric Analysis (TGA) technique at various heating rates and different fuel MC levels. The combustion properties of the selected structural fuels were measured by using the Cone Calorimeter at various HF levels and different fuel MC levels.
