Common issues found on Boiler feed water like corrosion and

The boiler manufacturers stipulate a maximum allowed salinity of the boiler water (as a rule at 0.4° Be = 4000 mg salts dissolved per litre). If this value is exceeded, there is a risk of normal bubble size being prevented; larger bubbles will be produced and the turbulence in the water surface will increase and cause foaming.

How to Destroy a Boiler -- Part 1 - National Board of Boiler

High conductivity or contamination of the boiler feedwater can create other problems such as drum level instability and foaming. This can result in high or low-water alarms and an increase in the carryover of moisture droplets into the steam header since the moisture separator of the drum cannot handle the resultant carryover.

Boiler Water Conductivity Measurement Fundamentals

The main aspects are the great temperature difference and high pH. An increase in temperature results in an increase in electrical conductivity. For boiler water, the conductivity increases at the rate of approximately 2% (of the value at 25°C) for every 1°C increase in temperature. This can be written as:

Boiler feedwater - Wikipedia

Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it then goes back to the steam drum to complete its cycle. The feed water is never open to the atmosphere. This cycle is known as a closed system or Rankine cycl
