Hydrogen analyzer HYDROLYT LP 100
The patented analyzer is used in power plants (conventional or nuclear) to determine the residue hydrogen concentration in boiler feed-water, the monitoring the hydrogen concentration during the denitrification ( removal nitrate NO3-) of drinking water or the indication of the hydrogen during the catalytic reduction of oxygen on noble metal surfaces in water treatment plants (bright gas reaction) etc. The measuring range is between some µg/l (trace areas) up to saturation levels.
The hydrogen in a water/steam loop of a power plant is manly produced by the reaction between iron and water or steam. One of several possible reaction steps for the proceedings according to the plant operation is:
3 Fe + 4 H2O => Fe3O4 + 4 H2
This reaction is named Schikorr-reaction. The hydrogen concentration generated through this process gives quantitative and qualitative evidence of the rate of corrosion and corresponds to the building or destruction of the protective layer in the pipes and boilers.
The sensor has an automatic in-line calibration. A stainless steel electrode is used in the calibration process. This electrode produces a certain amount of hydrogen by electrolysis.
