PROBLEM TO BE SOLVED: To provide a heat quantity calculation device and a heat quantity calculation method that can precisely heat wet steam flowing in piping. ! SOLUTION: A heat quantity calculation device relating to the invention comprises: a first detection unit that detects light, which passes through or is reflected by wet steam flowing in piping, at a first position; a second detection unit that detects the light at a second position different from the first position in an axial direction of the piping; dryness measurement unit that measures first dryness of the wet steam on the basis of intensity or absorbance of the light detected by the first detection unit and measures second dryness of the wet steam on the basis of intensity or absorbance of the light detected by the second detection unit; and a heat quantity calculation unit that calculates heat loss between the first position and the second position in the piping, on the basis of the first dryness and the second dryness measured by the dryne |
