Using caustic soda will, therefore, lower water hardness to a level that is equal to twice the reduction in bicarbonates belonging to the alkaline-earths. The waters M-alk. can only be lowered to approximately 3 or 4°F if there is sufficient permanent hardness available to combine with the sodium carbonate formed.

The hardness of water is harmful to the boilers as the deposition of salts occurs, which reduces the efficiency of the boiler. Hard water is safe to drink but using over a long interval of time can lead to many problems like: Strains in skin; Water appliances work harder resulting in higher water bills;

heat - How does boiling water affect its hardness

Does boiling water reduce its hardness, or on the contrary, increase it? It seems there are ambivalent phenomena at play here: boiling will evaporate pure water, thus increasing the concentration of minerals including calcium, thereby increasing hardness; boiling will remove $ce{CO2}$, making apparently $ce{CaCO3}$ precipitate, thereby reducing hardness

May 27, 2020 · The degree of hardness is classified as follows: The main problem associated with hardness is scale and deposits formation. Even levels as low as 5 to 8 mg/L are too extreme for many uses (i.e. as boiler feed water). Hardness, and in particular calcium, tend to precipitate coupling with anions like carbonate, phosphate or sulphate.

May 03, 2018 · Hardness contamination of the feed water may arise due to a deficient softener system. Deposits and corrosion result in efficiency losses and may result in boiler tube failures and inability to produce steam. Deposits act as insulators and slow heat transfer. Large amounts of deposits throughout the boiler could reduce the heat transfer enough

Boiler water treatment - Lenntech

Chemical treatment of water inside the boiler is usually essential and complements external treatment by taking care of any impurities entering the boiler with the feed water (hardness, oxygen, silica, etc.). In many cases external treatment of the water supply is not necessary and the water can be treated only by internal methods.

Boiler Water Treatment Guidelines; Columbia Boiler Co

The alkalinity of boiler water should be sufficiently high enough to protect shell and plates against acidic corrosion, but not high enough to produce carryover. A minimum value for alkalinity for adequate protection is 200 PPM. High boiler alkalinity, which is in excess of 700 PPM, should be avoided. Values higher than this can lead to embrittlement of the steel. Phosphates. Phosphates are used to react with calcium hardness in the boiler water.
