Abstract

A corrosion prevention device includes: a first light source unit (32A) provided with a light emitting diode that emits irradiation light in an absorption wavelength band that includes an absorption spectrum of a first measurement target produced by combustion of a combustion object; a second light source unit (32B) provided with a light emitting diode that emits irradiation light in an absorption wavelength band that includes an absorption spectrum which is an absorption spectrum of a second measurement target produced by combustion of the combustion object and is different from the absorption spectrum of the first measurement target; a first light receiving unit (34A) that receives the irradiation light emitted from the first light source unit (32A); a second light receiving unit (34B) that receives the irradiation light emitted from the second light source unit (32B); and a calculation unit (52) that calculates absorbance and/or transmittance of the first measurement target in a combustion gas generated by combustion of the combustion object, based on transmitted light intensity I1 of the irradiation light received by the first light receiving unit (34A) and transmitted light intensity I2 of the irradiation light received by the second light receiving unit (34B).
