Chapter 12 Boiler Deposits: Occurence And Control | SUEZ

Combinations of polymer, phosphate, and chelant are commonly used to produce results comparable to chelant/polymer treatment in low- to medium-pressure boilers. Boiler cleanliness is improved over phosphate treatment, and the presence of phosphate provides an easy means of testing to confirm the presence of treatment in the boiler water.

Containment Sump Neutralization Using Trisodium Phosphate

Long-term iodine retention may be assumed only when the equilibrium sump solution pH is above 7. This pH value should be achieved by the onset of the spray recirculation mode. A trisodium phosphate (TSP)-based, passive system can be used to achieve this pH value. This is a proven technology that is already in use in nuclear power plants.

Boiler Feedwater Treatment (Part I): Why Water Treatment

Boiler feedwater. Boiler 'feedwater' is the water supplied to the boiler. Often, steam is condensed and returned to the boiler as part of the feedwater. The water needed to supplement the returned condensate is termed 'make-up water'. Make-up water is usually filtered and treated before use.

13. Fire the boiler at a very low firing rate to limit the flue gases entering the boiler to a maximum of 800°F. Alternately, introduce 5 psig steam from an outside source through the blowdown nozzles. 14. When the boiler begins to produce steam (as seen though the open vents), allow the unit to steam freely for at least four hours.

Phosphate buffers the boiler water, reducing the chance of large pH changes due to the development of high caustic concentrations. Excess caustic combines with disodium phosphate and forms trisodium phosphate. Sufficient disodium phosphate must be available to combine with all of the free caustic in order to form trisodium phosphate.
