Temperature Scale VOLCANO CLASSIC
Air temperature table for the VOLCANO Vaporizer Scale:
The temperature of the air fluctuates between the declared value in order of the heating and cool off process of the heat exchanger always around ± 9°F (5°C). So for example at grade 6 between 365°-383°F (185°-195°C)
The temperature was measured (when the air was streaming) in the middle of the filling chamber at the lower screen with an fast reacting, electronic thermometer.
Cellulose (organic material or plant material) has a point of spontaneous combustion at 455°F (235°C) and higher.
