Boiler water or steam boiler feed water

Dissolved oxygen, Hydrazine, Sodium, Silica measurement for boiler water

 

Measurements for steam boiler water or boiler feed water

we have a complete program for steam boiler measurements. The parameters are:

  • Dissolved Oxygen
  • Hydrazine
  • Sodium
  • Silica

Dissolved oxygen at a very low level with a resolution of 0.1 ppb

The need for accurate monitors and accurate measurement of dissolved oxygen is essential for efficient, cost-effective operation of the steam boiler installation. In his
dissolved form, oxygen is highly corrosive to most metals, especially the mild steel used for boiler pipes. The presence of even small amounts of dissolved oxygen in boiler water can seriously interfere with boiler operation and cause corrosion. This significantly reduces operation and shortens service life.

  • Maintenance-free dissolved oxygen sensor eliminates the need to replace membranes or replenish electrolytes
  • Automatic calibration minimizes manual intervention and ensures accuracy
  • Thanks to the fast response time, rapid changes in plant conditions can be monitored
  • Intuitive software with graphical color display Datalogging and graphical process trending
  • Full audit trail capability
  • Secure data archiving on SD card or USB stick

Hydrazine

The Navigator 500 Hydrazine Analyzer provides a continuous measurement of the hydrazine content in boiler feed water, allowing the chemical dose to be controlled automatically. This avoids both the costs associated with overdosing and the costly corrosion damage caused by underdosing.

  • Low reagent consumption and a new design with no moving parts reduces maintenance requirements and minimizes costs
  • Thanks to the fast reaction time, the chemical costs can be reduced by optimum dosing of the feed water from the steam boiler
  • Automatic calibration minimizes manual intervention and ensures accuracy
  • Intuitive software with graphical color display
  • Data logging and graphic process trending
  • Full audit trail capability
  • Secure data archiving on SD card or USB stick

Sodium

The Navigator 500 sodium analyzer continuously measures the sodium ion concentration in de-mineralization plants and in the steam / water cycle of steam generation.

  • Measure up to 3 different sample flows with a single analyzer
  • Automatic electrode regeneration provides electrode sensitivity when measuring sodium traces
  • Low reagent consumption and a new design with no moving parts reduces maintenance requirements and minimizes costs
  • Automatic calibration minimizes manual intervention and ensures accuracy
  • Grab sample facility allows unattended analysis of manually collected samples
  • Intuitive software with graphical color display
  • Data logging and graphic process trending
  • Full audit trail capability
  • Secure data archiving on SD card or USB stick

Silica

The ABB Navigator 600 Silica Analyzer significantly reduces the costs and maintenance associated with silica monitoring in power generation and other large scale steam and water dependent applications. Typical applications for the Navigator 600 Silica are:

  • Demineralization plants for energy and process industries.
  • Monitoring of the anion exhaust and mixed beds for breakthrough silica, with indication of bed
    exhaustion and ultimate water quality of steam boilers systems.
  • Drum water boiler monitoring, providing information about the pollution levels in the boiler.
  • Monitoring the transfer of silica into saturated steam thus protecting turbine blades from potentially excessive scale build-up.
  • Monitoring the exhaustion of ion exchangers in a condensate polishing installation.

Characteristics:

  • Analysis of up to 6 sample streams
  • Up to 90% lower reagent consumption than other silica analyzers
  • Labor-saving annual maintenance of 5 minutes and up to 3 months without supervision
  • Automatic cleaning and calibration
  • True auto-zero compensation compensates for sample color, turbidity and background silica in reagents

What can we do for you?

  • It is possible to install and commission the measurement for you
  • Do the maintenance for you
  • We can help you with a question
  • We can supply you with spare parts
