Marine Boiler Water Treatment, TDS, Blowdown & Chemical Dosing Tool
Convert boiler-water test results into a controlled operating plan. Simple mode sizes steady TDS blowdown, estimates corrective purge volume when boiler water is already above target, and calculates a product correction dose from a supplier dose-response factor. Advanced mode adds condensate return and make-up blending, conductivity cross-checks, blowdown heat loss, chemistry-control registers, multi-product dosing, stock runway and a feedwater-TDS × target-TDS sensitivity map.
Current Boiler Water Condition
Boiler & Operating Basis
Feedwater Solids Basis
Use a measured feedwater TDS or estimate it from condensate return and make-up water. The blend is a simple concentration balance and does not replace actual feedwater sampling.
TDS / Conductivity Control
Water Chemistry Control Register
Enter the vessel's actual control band. Blank low/high limits are treated as “not configured.” This avoids hard-coding one boiler-treatment program across different pressures, makers and chemicals.

Chemical Dosing Register
Correction dose is only calculated when a valid supplier dose-response factor is entered. Routine dose is independently entered as litres of product per tonne of boiler feedwater. This prevents the tool from inventing a universal chemical concentration.
| Use | Product / program | Current residual | Target residual | Dose response | Routine dose | Stock L | Density kg/L | Cost / L |
