Which two key properties are assessed in feedwater quality?

The assessment of feedwater quality is crucial for ensuring the efficiency and longevity of boiler systems. Total dissolved solids (TDS) and pH level are two key properties that help in evaluating the purity and corrosiveness of the water.

Total dissolved solids refer to the combined content of all inorganic and organic substances in the water that can pass through a filter with a pore size of 2 micrometers. High levels of TDS can lead to scaling, corrosion, and other operational issues within boilers. It is essential to monitor TDS to maintain optimal performance and prevent harm to the system.

pH level is another critical parameter as it indicates the acidity or alkalinity of the water. A pH level that is out of the normal range can lead to corrosion of metal components in the boiler system. Maintaining the pH within an acceptable range helps to minimize corrosive effects and ensures the integrity of the equipment.

These two properties are fundamental because they directly influence the chemical characteristics of feedwater and can affect the overall operation and maintenance of feedwater systems, making them vital parameters to assess for ensuring safe and efficient boiler operation.
