ABSTRACT OF THE DISCLOSURE A long heating pipe is laid along a conveyor pipe and in contact with the outer surface thereof. The heating pipe is provided with an outer tube which has an operating fluid hermetically contained therein, and a steam tube which is inserted through the outer tube. A container is provided to accumulate condensation created as a result of the liquefac- tion of vapor fed through the steam tube of the heating pipe. This container has a temperature sensing valve located therein. The temperature sensing valve is closed if the condensation within the container more rises in temperature than predetermined, and this valve is opened if the condensa- tion within the container more decreases in temperature than predetermined. This temperature sensing valve is communica- tively connected to the downstream side end portion of the steam tube of the heating pipe, which is inserted into the container.
