Problems STEAMPLAN Solutions Water used to generate steam contains various impurities, the most typical being compounds of calcium, magnesium, silica and iron. In an Control of Boiler - Water chemistry, before and after the Water enters system where impurities are allowed to reach excessive the steam generating system, is vital to efficient operation, acceptable maintenance costs, and satisfactory equipment concentrations, steam quality can be impaired.

4 In addition, hardness service-life. salts can precipitate from the Boiler Water to form sludge and eventually scale, which deposits on the internal surfaces of the Boiler . All-In-One Programs - Liquid blends of alkalinity The result: a serious loss of Boiler efficiency, and possibly Boiler builders/polymers and sulfite designed as one of the single drum failure. and advanced treatment for high pressure boilers (AVT). Scale is a buildup of solid material formed on internal Boiler surfaces when the concentration of impurities in the Boiler Water exceeds their Oxygen Scavengers - Products in this group represent inorganic solubility limit and precipitation occurs.

5 Hardness compounds and organic catalyzed oxygen scavengers. These products cover all pH ranges and concentrations, and are available in liquids and predominantly calcium and magnesium salts collect on heat-transfer powders. Also, more effective products for Boiler lay-ups are surfaces in the form of a sludge that typically also contains iron, available. organics and other impurities. Corrosion is the destruction of a metal by electromechanical reaction Alkalinity Builders - Liquid alkalinity builders to prevent acid attack with its environment. In Boiler systems, that environment includes hot and amine based product with higher distribution ratio for Water with a low pH or slightly acid condition and some degree of condensate treatment.

6 Oxygen entrainment. Those conditions are ideal for corrosive action. Removal of carbon dioxide and oxygen from Boiler feedwater is Scale Prevention - Products in the group consist of the newest Tracer all polymers and phosphate technologies for effective scale essential to preventing Boiler -system corrosion. Condensation of CO2 in inhibition, crystal modification and sludge dispersion to ensure clean the condensate system results in the formation of highly corrosive surfaces. carbonic acid (H2CO3). Much more importantly, the presence of oxygen in the feedwater leads to oxygen pitting.

7 Condensate Treatment - Neutralizing and Filming amines are Foaming and Carryover are caused due to high dissolved solid and provided in a wide variety, utilizing formulation based on standards caustic alkalinity in combination with leakages, load changes and organic amines. matter ( oil).
