Combustion And Charring Properties Of Five Common Constructional Wood Species From Cone Calorimeter Tests

Abstract Cone calorimeter tests conducted at three levels of heat flux, 25, 50 and 75 kW/m2, were employed to investigate the combustion and charring properties of five common constructional wood species: three softwood species: Douglas fir (Pseudotsuga menziesii), Scots Pine (Pinus sylvestris) and Southern pine (genus Pinus), and two hardwood species: Shorea (genus Dipterocarpaceae) and Merbau (Intsia bijuga). The ignitability and combustibility parameters of these five species were calculated and the time to ignition, heat release and mass loss rates, specific extinction area, effective heat of combustion, and CO and CO2 yield compared. The measured charring rates from the cone calorimeter tests were transformed to equivalent charring…
