Generally, 200-400 ppm P-alkalinity is maintained in the water for effective control of pH. Inhibitor requirements vary depending on the system. Electric boilers are also used for heating. There are two basic types of electric boilers: resistance and electrode. Resistance boilers generate heat by means of a coiled heating element.Get Price
In medium pressure boilers (20-40 atm), 200 ppm p.Alkalinity must be the maximum limit. In high pressure boilers (40-100 atm), 100 ppm p.Alkalinity must be the maximum limit. In case that alkalinity is above these ranges the system must be brought to ideal ranges by partial bluffs.Get Price

In this case, the alkalinity value should not exceed the maximum value. For low-pressure steam boilers, this is typically 26 mg-eq/l. Then, having determined the optimal value of the boiler water alkalinity, it is necessary to determine the flow rate of continuous blowdown of the boiler water according to equation (2).Get Price
The level of alkalinity within low-pressure boilers should not exceed 700 ppm. The presence of alkalinity above the 700 ppm level can result in a breakdown of the bicarbonate producing carbonate and liberate free carbon dioxide with the steam. The presence of carbon dioxide in the steam usually results in high corrosion of steam and return lines.Get Price

In cooling water, treatment professionals aim to …Get Price
Alkalinity in the boiler, as well as minimising corrosion, also acts as a scale salts precipitant. As an example caustic alkalinity in the boiler will precipitate magnesium salts to form a mobile sludge that can be easily removed by blowdown, e.g. MgCl 2 + 2NaOH >> Mg (OH) 2 + 2NaClGet Price
