WebAs per BS Std 845, a D.O level of 2 ppm in boiler feed water is acceptable. It means, raising the temperature of feed water above 90 degree C can reduce the level of dissolved oxygen below the acceptable levels. Oxygen scavengers can also be added to reduce the dissolved oxygen levels in the feed water. WebThe impurities must be blown down by the discharge of some of the water from the boiler to the drains. The permissible percentage of blown down at a plant is strictly limited by running costs and initial outlay. The tendency …

WebOver the past few years we have worked together to tackle water treatment challenges with cooling water, boiler feed water and boiler water chemistry control, reverse osmosis units and also with waste water treatment where he has developed an understanding of optimising chemical injection at DAF units and activated sludge/SBR process control.
WebBoiler feed water is used to produce steam. The pressure of the steam (0,5 - 100 bar) determines the temperature and energy capacity, but also the quality of the feed water. The general rule is the higher the pressure the more strict the quality of the boiler feed water.
