うとするものである。The present invention was developed as a result of various studies to find out that the cooling device is not required when using an endothermic type Ganu in a heat treatment furnace, and that the high temperature atmosphere inside the furnace can be used as a heat source for a gas conversion retort. The endothermic type Ganu generator is equipped with a modified retort which is filled with a catalyst and has a raw material Ganu carp supply port at one end and a modified gas outlet at the other end, and this retort is surrounded by a heat retaining member. In addition, an electric heating element is arranged between the metamorphic retort and the heat retention member,
This made it possible to attach stone to the furnace. That is, the catalyst is always maintained at a predetermined temperature by the furnace atmosphere temperature 2 and an electric heating element, and the source gas is converted into a modified gas with a constant composition.
By directly discharging this converted gas into the furnace, we aim to save energy compared to conventional ones, and provide an endothermic gas generator that can be installed inside the furnace and eliminates the need for a cooling device. be.

っている。The amount of heat required to transform the raw material gas into a totally endothermic gas in the catalyst layer 12 is mainly generated by the electric heating element 16, but if the temperature inside the furnace is high, the heat retention part 6 is utilized. The accuracy in the retort 8 is determined by controlling the amount of light from the electric heating element 16 by opening and closing the switch 23 at a ratio of 11 to the signal set by the total temperature controller 22 from the thermocouple 17.
The temperature of the catalyst layer 12 is maintained at 800 to 1050°C, which is sufficient for the reaction of the raw material gas to occur.
