STEAM DRUM WATER LEVEL MEASUREME

The ASME Boiler and Pressure Vessel Code Section I establishes the requirements for steam drum water level measurement in fired steam drums. The primary focus of these requirements is safe boiler operation. Maintenance, performance, and other specific application issues are not addressed.

Low-Pressure Steam and Hot Water Heating Systems. Hot water boilers heat and circulate water at approximately 200°F. Steam heating boilers are used to generate steam at low pressures, such as 15 psig. Generally, these two basic heating systems are treated as closed systems, because makeup requirements are usually very low.

Pressure of HP drum is 120. We have facing problem of low pH (5-8) and Low PO4 in HP drum in spite of continuous dosing of Tri Sodium Phosphate. Conductivity of boiler water is also high, i.e., about 200 µs/cm. While Feed, Hot well condensate pH and steam pH is ok. We're dosing Ammonia and Hydrazine in feed water system.

It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic (alkaline). Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6.

Though separation devices in drum boilers remove most water droplets carried by steam, some residual droplets containing small amounts of dissolved solids always carry through with the steam. Also, at higher pressures, there is some vaporous carryover.

better results in boiler water treatment (i.e., cleaner boilers). The important key to success is to use the same care in selecting, applying, and controlling the treatment program. Chelating programs are another variation of water treatment. The word chelate derives from the Greek word chele, meaning claw. This was probably chosen because of the
