The effect of preheating of wood on ignition temperature of wood char

Samples of solid cottonwood in the form of discs have been heated at 250°C in both air and nitrogen, up to 12 h, and in air at 150°C up to 30 days. The preheated samples were then further heated in air at 5°C/min to unpiloted ignition. Despite major chemical changes during the various preheating tre...

Description
Summary:Samples of solid cottonwood in the form of discs have been heated at 250°C in both air and nitrogen, up to 12 h, and in air at 150°C up to 30 days. The preheated samples were then further heated in air at 5°C/min to unpiloted ignition. Despite major chemical changes during the various preheating treatments, the ignition temperatures were not significantly affected, except for a slight decrease (11 °C) after 5 days at 150°C in air.
