Abstract
An ammonia compound concentration measuring device includes: a pipe unit through which the circulating gas flows; a converter which is disposed in the pipe unit and converts an ammonia compound into ammonia; a measurement device which measures a first measurement value as a concentration of ammonia contained in a first circulating gas flowing inside a pipe line passing through the converter in the circulating gas flowing inside the pipe unit and a second measurement value as a concentration of ammonia contained in a second circulating gas flowing inside a pipe line not passing through the converter in the circulating gas flowing inside the pipe unit; and a controller which controls operations of the pipe unit and the measurement device and calculates the concentration of the ammonia compound of the measurement subject contained in the circulating gas from a difference between the first measurement value and the second measurement value.
