Thermal Decomposition Behavior of Wood in a Test Tubeunder Localized Infrared Heating

Wood placed inside a test tube was locally irradiated with infrared radiation, and its behavior during heating was observed.
The irradiated area rapidly increased in temperature, causing thermal decomposition of the wood and the release of volatile components.

The generated volatile components were cooled and condensed due to the temperature gradient inside the test tube, resulting in the deposition of tar-like and oily substances on the inner wall.

This experiment demonstrates the visualization of the thermal decomposition process of wood and the behavior of its decomposition products through non-contact, localized heating.
