Jul 03, 2010 · The boiler drum is where water and steam are separated. Controlling its level is critical – if the level becomes too low, the boiler can run dry resulting in mechanical damage of the drum and boiler piping. If the level becomes too high, water can be carried over into the steam pipework, possibly damaging downstream equipment. The design of

Liming 0183; Maximum TDS allowed in the boiler in ppm For example: To keep a steam boiler producing 4000 kghr of steam below 3500 ppm TDS when fed from a feed tank having a TDS of 80ppm, it will need to blowdown at least; F 80 ppm 80 215; 4000 = 93.6 kghr S 4000 kghr 3500 − 80 B 3500 ppm Typical permissible levels …
Read MoreHence, an appropriate level of water must always be maintained in a boiler drum. This level control is always done at constant steam load demand. Three types of drum-level control designs mainly exist for boiler applications which include single-element drum-level control, two-element drum-level control and three-element drum-level control.
