摘要： One end side of a core wire holder 20 is formed into a shape of a truncated cone and has an inclined surface. In the end portion, an opening 22 is provided, and a hollow portion 21 is formed, a silicon core wire 5 being inserted into the hollow portion 21 and held therein. On the surface of the silicon core wire 5, polycrystalline silicon 6 is vapor deposited by the Siemens method to produce a polycrystalline silicon rod. On the inclined surface of the truncated cone portion in the vicinity of the opening 22, as a thermal insulating layer, annular slits 23a to 23c are formed from an outer circumferential surface in the vicinity of the opening toward the hollow portion 21. The annular slit acts as a thermal insulating portion, and suppresses escape of the heat to heat the one end side of the core wire holder 20.

摘要： The present invention provides a technique by which heat can be efficiently recovered from a coolant used to cool a reactor, and contamination with dopant impurities from an inner wall of a reactor when polycrystalline silicon is deposited within the reactor can be reduced to produce high-purity polycrystalline silicon. With the use of hot water 15 having a temperature higher than a standard boiling point as a coolant fed to the reactor 10, the temperature of the reactor inner wall is kept at a temperature of not more than 370° C. Additionally, the pressure of the hot water 15 to be recovered is reduced by a pressure control section provided in a coolant tank 20 to generate steam. Thereby, a part of the hot water is taken out as steam to the outside, and reused as a heating source for another application.
