Two analyzers for boiler feedwater, steam and more
The CA76NA monitors sodium, while the CA80SI (photo) analyzes for silica in boiler feedwater, steam, condensate and ion exchangers. Each analyzer can accept up to six sampling inputs. The CA76NA potentiometric analyzer measures the concentration of dissolved sodium ions. An increase in sodium levels in boiler feedwater indicates the presence of unwanted dissolved impurities. This can cause corrosion, leaks, serious damage and expensive repairs. The analyzer monitors the water/steam circuit in power stations, condensate systems for values indicating ruptures, demineralization systems, steam and cation systems, and mixed-bed exchangers. The Liquiline System CA80SI colorimetric analyzer provides precise online analysis of silica to protect plant equipment from deposits to ensure optimum performance of turbines and ion exchangers. Deposits of insoluble SiO2 on internal boiler walls, heat exchangers and turbine blades have an adverse effect on the efficiency of power plants and increase the risk of unplanned downtime and repairs. For this reason, the silica content in boiler feedwater must be monitored. — Endress+Hauser, Greenwood, Ind.
