<p>This invention aims to propose a heating system utilizing the microwave improved to manufacture the high quality fibers such as carbon fiber and graphitic fiber with a simplified construction and simultaneously to meet a demand for saving of the electric energy. This heating system includes microwave supplying means adapted to supply the heating furnace main body with microwave power, filtering zones respectively provided in the vicinity of an inlet 11a at one side of the heating furnace main body and in the vicinity of an outlet 11b at the other side of the heating furnace main body to prevent leak of the microwave power, a heating oven formed of microwave heat generating material in the form of an oblong hollow body so as to extend linearly between the inlet and the outlet of the heating furnace main body and heat insulator having low microwave absorption ability adapted to separate off a space defined between an inner surface of the heating furnace main body and an outer surface of the heating oven from a space within the heating oven and adapted also to hold the heating oven wherein a work or works is or are supplied through the into the heating oven and discharged from the outlet to heat the work or works within the heating oven.</p> |
