Abstract
A fluid heating device for heating chemicals mainly containing sulfuric acid, which is capable of suppressing reduction of heating efficiency even if a fluid mainly containing sulfuric acid is heated, includes a translucent inner tube composed of quartz or the like, a lamp heater disposed in the inner tube, a translucent outer tube disposed outside the inner tube, which is composed of quartz or the like, translucent side plates disposed on both sides of the outer tube, which include quartz or the like, and an amorphous carbon pipe disposed between the outer tube and the inner tube, which functions as a light-absorbing material, wherein the amorphous carbon pipe is disposed so as to be brought into contact with chemicals passing through a space between the outer tube and the inner tube.
