Three types of ignition in wood, Ignition, Flashing and Carbon-ignition, are classificated experimentally by difference of time lag. By this results, the following facts are made clear : —
(1) Three types of ignition are recognized at low temperature (<600°C).
(2) Three types are not separated at high temperature.
(3) Carbon-ignition break out more easily than flashing and ignition.
(4) Carbon-ignition is not obtained when air flow on the surface of wood is ceased.
(5) The theory given at the last report is applicable in flashing phenomenon.
Moreover, activation energy of thermal decomposition 36.9 kcal is determined from the theory in the last report and the results of experiment in this report.
