In a boiler feedwater system, the hot water is located between which two components?

• A. Between the softener and deaerator
• B. Between the deaerator and boiler
• C. Between the softener and boiler
• D. Between the pump and deaerator

Answer: (A)

In boiler feedwater systems, water is heated and treated in stages before entering the boiler, and temperature plays a key role in how effectively gases are removed. The softened water often goes through a preheater after treatment and before the deaerator, so the hot water sits between the softener and the deaerator. Heating the water beforehand helps reduce dissolved gases because warmer water holds less gas and makes deaeration more efficient. The deaerator then removes the remaining oxygen and carbon dioxide, after which the water is pumped to the boiler. This arrangement explains why the hot water is located between the softener and the deaerator.
