Boiler Chemicals - Oxygen, Scale, and pH Adjustments

Depending on plant conditions, the NH 3 concentration in feed water can achieve values of 5–10 mg/kg. This corresponds to pH(25°C) = 9.81–9.98 in feed water or pH(190°C) = 6.83–6.98. That means the hydrazine requirements satisfy simultaneously the need of high pH for general corrosion control.

Chemical Pretreatment For RO and NF - Hydranautics

There are two main groups of Chemicals for Boilers to choose from. One chemical group for boilers is for steam boilers and the second is for hot water boilers. Steam Boiler Chemicals - These include Oxygen Scavengers, Amines, Phosphates, Polymers, and Alkalinity Builders. Oxygen Scavengers - Most common type is 38%, pH < 4.

Role of hydrazine/reducing agent to develop the magnetite

The advantages of carbon filters are (1) its ability to remove organics from feed water that could foul the RO and (2) that they are more reliable in treating all the feed water than a chemical feed system. The disadvantage to using carbon filters is that they are notorious for breeding bacteria which can result in biological fouling of the RO.

Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica
