The Make-Up Feed (MUF) system uses a demineralizer to remove contaminants that are present in feedwater coming from the ______.

• A. Reserve feed tanks
• B. Condenser
• C. Engine room lube oil
• D. Freshwater storage

Answer: (A)

Make-Up water for the boiler is treated to remove dissolved minerals before it enters the feed system, preventing scale and corrosion. The water that needs this treatment is the makeup water stored in reserve feed tanks, which supplies the boiler when condensate return isn’t enough. Water from the condenser (condensate) is already high in purity and isn’t the source that goes through the MUF demineralizer. Engine room lube oil and freshwater storage aren’t the makeup source for the MUF either—the reserve feed tanks are specifically the makeup water source that requires demineralization.
