<p>When a heat treatment device for heating synthetic fiber filament yarns by saturated steam is installed to a drawing and texturing device for synthetic fiber filament yarns, in order to lower the total height of the devices than a conventional one, cylindrical hot pins each having a heat-absorbing part and a heat-discharging part are formed integrally with the bottom surface of a laterally extended container for sealing saturated steam of heat medium liquid in such a fashion as to penetrate through the bottom surface from inside to outside of the container with axes of the hot pins extending in a vertical direction, and the level of surface of the heat medium liquid within the boiler connected with the container is disposed at a position lower than the inside bottom surface of the container. <IMAGE></p> |
