High-Pressure Steam Cycle and Boiler Water Treatment

1/1/2008 · Boiler designers allow for a water level higher than the normal working level (NWL), providing sufficient area for the release of steam at a velocity low enough to avoid carryover. This ensures that the steam off-take does not exceed a specific height above the NWL.

Total Dissolved Solids - TDS

The safe pH range for steam boilers is between 8.5pH & 12.7pH, whilst the recommended level is between 10.5pH & 12.0pH. Boiler water with a pH of 10.5 contributes 12.6mg/l towards the boiler TDS, whilst at a pH of 12.0 it increases to 400mg/l and at 12.5pH the value is 1264.9 mg/l a 100 fold increase.
