Dec 23, 2009 · Water chemistry sensors for both feed water and boiler need monitoring as any impurities in this gets concentrated and gets carried over in the steam. Conductivity controls for water blowdown in the drum type boiler are a method to remove such concentrate. Conductivity is just one of many factors to monitor. Changes in conductivity readings in various area gives a good clue to operators to Learn More

For most dissolved solids found in boiler water, it is negligible by comparison to mechanical carryover at pressures less than 2000 psig (13.8 MPa). An exception is silica for which vaporous carryover can be substantial at lower pressures. Vaporous carryover depends on pressure and on boiler water chemistry. It is not affected by boiler design.Learn More
