Determination or control parameters in boiler systems.

CYCLES OF CONCENTRATION, PERCENTAGE OF RETENTION TIME OF LIFE FOR A COMPONENT IN THE BOILER AND MERGERS continuous treatment, are monitored or determined under a boiler system by adding to the feedwater tracer INERTE in a concentration CL DEFAULT, CF REACHING FINAL CONCENTRATION IN A PERMANENT STATE IN THE BOILER AND CT Exhibiting CONCENTRATION OF BLEEDING IN DIFFERENT POINTS IN TIME. The component is an inert tracer, which has ARRASTRES IMPORTANT DIRT WITH STEAM OR DEGRADATION SIGNIFICANT FOR THE CYCLES OF THE BOILER. PLOTTER is monitored by continuous conversion of a characteristic of concentration, to an analog can register as a function of time.
