ABSTRACT:
When a heat treatment device for simultaneously heat-treating synthetic fiber filament yarns with saturated steam of heat medium liquid stored in a plurality of closed containers is installed with other devices together, the total height of the installation is lowered than a conventional one in order to reduce the cost of a building for storing these devices. The closed container for saturated steam of heat medium liquid is formed longer in horizontal direction, the heating surface of an outer surface of the closed container is faced downwardly, and the heating surfaces of the closed containers are provided at positions higher than the heat medium liquid level in the boiler so that a boiler for heating the heat medium is not necessarily installed in each closed container, thereby manufacturing costs are also reduced.
