PROBLEM TO BE SOLVED: To simplify the structure of a carbon raw material-producing apparatus, efficiently promote carbonization and obtain a carbon raw material excellent in quality and useful for industries, etc., by thermally transferring the heat in a heat decomposition furnace from the high-temperature part to the low- temperature part to make the temperature distribution of the furnace uniform. SOLUTION: When organic matters such as organic matters contained in industrial waste, domestic garbage, etc., are thermally decomposed by low- temperature indirect heating under oxygen-free closed atmosphere replaced with nitrogen to produce carbon raw material in a heat decomposition furnace C, the heat in the heat decomposition furnace C is thermally transferred from the high-temperature part to the low-temperature part by a heat pipe F and temperature distribution in the heat decomposition furnace C is made uniform to provide the objective carbon raw material. Furthermore, it is preferable that the heat pipe F is arranged vertically in the heat decomposition furnace and a carbon raw material-producing apparatus is equipped with a decomposition gas treating part connected to the interior of the heat decomposition furnace C. |
