<p>PURPOSE: A heating rod aggregate for a high-temperature gas heating device is provided to absorb the thermal expansion of heating rods by inserting a neutral point rod between the heating rods and connecting the neutral point rod and the heating rods using a connection unit, thereby preventing damage to the connection unit or other components. CONSTITUTION: A heating rod aggregate for a high-temperature gas heating device comprises multiple heating rods (130) which are mounted in a reflector installed inside a pressure vessel while the upper part is exposed and which heats high-temperature gas; a neutral point rod (130d) which is mounted between selected heating rods among the multiple heating rods; and multiple connection units (140) which connect the neutral point rod and the selected heating rods. Among the connection units, a connection unit connected to a heating rod with a high thermal expansion coefficient is placed at an upper position.</p> |
