What is Carryover | Causes of Carryover - Forbes Marshall
On off operation of boiler feed pumps a cause for carryover in flue tube boiler. It can be practiced only when the drum size is big as in an oil-fired boiler with internal furnace. In external furnace cases, the steam space is less, thus feed water regulation would give purer steam.

How Boiler Feedwater Quality Can Affect Boiler Operations
2021/9/17 · Prevent boiler system failures by understanding how impurities affect your system. Learn more about how boiler feed water system can help. Dissolved solids such as calcium, magnesium, iron, and silica in feedwater can damage a boiler beyond repair. These
Water-tube boiler plant is much less tolerant of high TDS levels, and even less so as the pressure increases. This is due to a number of reasons, including: Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate.
