- Abstract
- A simple fire-retardant treatment for wood is described. The treatment involves preheating the wood surface at high heat flux (~0.6 cal/cm(2) sec) to form an in-stu surface char layer (~3 mm thick) on the wood. Laboratory-scale fire tests show that the precharring technique improves the fire-resistance of virgin wood by decreasing and delaying generation of volatile gases through thermal insulation effect of the surface prechar-layer.
