Boiler Feed Water Tds Limit


2015-10-22·Foaming may occur if the alkalinity of the water is too high, the boilers TDS levels are too high, there is excessive contamination in the condensate return, the dosage of polymers is too great, or increased boiler concentrations. Foam forms in the space between the water surface inside the boiler and the steam off-take.

Steam Purity - Western Regional Boiler Association Home

Causes of Poor Steam Purity Foaming in the boiler caused by organic contamination (oil, high total organics from the makeup water, high boiler water TDS). High chemical contamination caused by excessive TDS due to lack of boiler blowdown. Excessive alkalinity due to excess hydroxide feed in the boiler water.

Marine Steam Boiler Water Test Procedures,

In steamships boiler feed water consists of condensate returns along with make-up feed water. The testing of boiler feed water is imperative to prevent many conditions which are detrimental to safe, efficient boiler steaming. These main culprits are high acid and oxygen content causing corrosion and pitting inside the water tubes and boiler internals.
