Internal Boiler Treatments In most cases, external treatment (pretreatment) is the first step in treating a boiler’s water supply. However, boiler water internal treatment is still required to prevent loss of heat transfer efficiency and shortened life of capital equipment.
External water treatment can be done in many ways such as softening, deaeration, ion-exchange, evaporation, and chemical treatment. In internal treatment, boiler water treatment chemicals such as phosphate and polyphosphate dispersants, tannins, lignosulfonates, nitrite and sodium sulfite among others are used to achieve various objectives.
Boiler feedwater treatment. These treatment chemicals also help with the alkalinity of the feed water making it more of a base to help protect against boiler corrosion. The correct alkalinity is protected by adding phosphates. These phosphates precipitate the solids to the bottom of the boiler drum.
Two major types of boiler water treatment are: Internal water treatment and External water treatment. Internal Water Treatment. Boiler Internal treatment is carried out by adding chemicals to boiler to prevent the formation of scale by converting the scale-forming compounds to free-flowing sludge, which can be removed by taking blowdown.

Boiler water treatment chemicals are the chemicals used in treating the feedwater that are used inside the boilers. there are different boiler water treatment methods.
The internal treatment of boiler water involves a variety of solutions that can be placed directly into the boiler system in an attempt to prevent higher conductivity or to lower conductivity that has already reached a high measurement. As with external treatments, there are many methods and techniques that can be used via internal treatments.
Internal water treatment is a) used with low pressure boilers only b) adding chemicals to the boiler water c) adding a coagulant to the settling tank d) measuring the pH of the feedwater e) adding chemicals to the steam in the boiler
In internal treatment, boiler water treatment chemicals such as phosphate and polyphosphate dispersants, tannins, lignosulfonates, nitrite and sodium sulfite among others are used to achieve various objectives.
Boiler water treatment chemicals must enhance continuous heat exchange, corrosion protection, and high quality steam production. Scaling and corrosion are the two key heads that adversely affect the boiler system efficiency. Different treatments are used to avoid scaling, corrosion, and/or foaming.
Jun 26, 2017 · Chelants such as Na 4 EDTA and Na 3 NTA are used as internal treatments for scale control in boilers. Chelants must be used with oxygen scavengers, alkalinity builders, antifoam, and polymer additives for a complete boiler water treatment program.
