Why hard water is not used in industrial boilers for producing steam? |
|
Answer» ter has minerals which will coat the inside of boiler TUBES for water tube boilers and the outside of tubes for fire tube boilers. Either WAY, when this OCCURS, the heat of the fire cannot transfer easily through the tubes to the water because the attached minerals is a very good insulator. This means the metal boiler tubes GET hotter than designed and can begin to sag. Ultimately the tubes can overheat, and pinhole leaks can begin to occur, or a major overheating event of SAGGING tubes.This then requires retubing of the boiler and is a major loss. |
