Disasvantages Of High Tds For Boiler

Foaming and priming in boilers - Lenntech

Boiler water carry-over is the contamination of the steam with boiler-water solids. Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This is called foaming and it is caused by high concentration of any solids in the boiler water. It is generally believed, however, that specific substances such as alkalis, oils, fats, greases, certain types of

Effect of Dissolved Gases in Feed Water - Forbes Marshall

Carbon dioxide enters the system with the boiler feed water in dissolved form & in form of bicarbonates. The carbon dioxide is carried away with the steam & is condensed to form carbonic acid. Carbonic acid has a capacity to combine with one and a quarter pound of steel per pound of CO2, forming a groove at the bottom of the piping .

How to Destroy a Boiler -- Part 1

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.
