Title:
AMMONIA COMPOUND CONCENTRATION MEASURING DEVICE AND AMMONIA COMPOUND CONCENTRATION MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/161839
Kind Code:
A1
Abstract:
The disclosed ammonia compound concentration measuring device measures an ammonia compound to be measured which is included in circulating gas, and comprises: a piping unit through which circulating gas flows; a conversion means which is arranged in the piping unit and which converts an ammonia compound into ammonia; a measuring means which measures, from among the circulatory gas flowing through the piping unit, a first measurement value which is the concentration of ammonia contained in first circulating gas which has flowed through a piping path which passes through the conversion means, and a second measurement value which is the concentration of ammonia contained in second circulating gas which has flowed through a piping path which does not pass through the conversion means; and a control means which controls the operation of the piping unit and the measuring means, and calculates the concentration of the ammonia compound to be measured which is contained in the circulating gas, from the difference between the first measurement value and the second measurement value. The device measures by means of a near-infrared laser light.
