Abstract
A carbonizing furnace includes a heating chamber with a wall having channels therein, a carbon heater in the channels, a heat insulator composed of carbon fiber felt and a ceramic fiber felt which covers the heating chamber such that the carbon fiber felt is in contacting with the heating chamber and the ceramic fiber felt is separated by a space from the carbon fiber felt, and a housing enclosing the heating chamber and the heat insulator, and an inlet for filling the insulator with an inert gas. The carbonizing furnace can be run stably and continuously.
