Measurements of pH, dissolved oxygen, conductivity, and chemical analysis for hydrazine and silicate are important, even in relatively small boilers
Endress+Hauser offers a range of products for control of the water/steam cycle in thermal power generation.
Basic measurements like pH, dissolved oxygen (DO) and conductivity are supplemented by chemical analysers for hydrazine and silicate.
All of these measurements are important, even in relatively small boilers.
The measurement of pH in pure water is widely acknowledged as a difficult task.
In the past, Endress+Hauser solved the problem with a traditional sensor with liquid (flowing) KCl electrolyte and reservoir.
However, the new Purisys CPF201 compact sensor is pre-filled with a large supply of solid KCl crystals and has no need for regular solution top-up.
Mounted in a stainless steel flow cell with low included volume, Purisys simplifies pH measurement of pure water.
The trace DO (ppb level) sensor also uses a compact low volume flow cell, helping to minimise water consumption and maximise response.
For hydrazine and silicate monitoring, Endress+Hauser's Stamolys photometric analysers are ideal, having only small sample and reagent requirements.
In addition to being one of the most accurate units available, they are also very economical to run and provide a particularly fast response.
Automatic self-cleaning and calibration ensures that the Stamolys units perform accurately and consistently over long intervals with minimal operator intervention.
