First there should be a back flow preventer so the boiler water can not travel back into your potable water. Oil could have entered the system during installation. Oil is used during pipe threading and if is not cleaned off could have been left in the system when the water was turned on. Also there is some oil in some thread sealants which if too much have used could have entered your system. Not sure why you are asking but this could cause problems in a steam heating system causing the water to surge back and forth. This can be fixed by heating the boiler and letting the oil flow out of a draw off at the top of the water level while adding more water. If doing this you want to make sure you have enough water in the boiler so that it doesnt get damaged from the heat.
ALL Boilers by decent codes require a back flow preventor NOT just a check valve UNLESS the boiler is fed though an air gap which is the best possible ptrotection for the potable system
What else can I help you with?
If oil is mixed with boiler feed water?
If oil is mixed with boiler feed water, it can cause scaling and fouling in the boiler system, leading to reduced efficiency and potentially damaging the boiler components. It is important to prevent oil contamination of boiler feed water through proper filtration and maintenance of equipment to ensure the smooth operation of the boiler system.
What is the PH value in boiler feed water?
The pH value in boiler feed water is typically maintained between 8.5 and 9.5. This range helps to prevent corrosion and scaling in the boiler system. Regular monitoring and adjustment of pH levels are important to ensure the proper functioning and longevity of the boiler.
What is boiler feed water pump?
Boiler feed pumps are an important part of any boiler operation. They control the amount of water fed to the boiler and the manner in which it is fed.
What is boiler feed water?
Boiler feed is the fresh or treated water to replenish the water loss though evaporation or leak
What is the function of a cold feed and expansion pipe?
Cold feed is cold water that supplies boiler water for heating system. Expansion tank relieves excess pressure buildup in heating system.The Cold feed should enter the supply line rather then the return as not to thermo shock a boiler and the expansion tank is to protect the system from excessive pressureAs water is heated it expands causing higher pressures the tank acts an asorber for this expansion
What is digester feed pump?
A digester feed pump forces water to a boiler. It works by transferring cool water to the boiler to be heated.
How do close formula feeds differ from open formula feeds?
The feed system cycles between boiler and turbine and enables the steam to return to the boiler as feed water. A closed feed cycles a main propulsion steam run turbine through a high pressure water tube boiler. The condenser, set to a high vacuum, will receive the steam turbine exhaust.

What is Boiler feed pump?
Function - It adds the pressure to the feed water before it entyers into boiler feed pump suction Advantage - Ensures high margin NPSH A for boiler feed pump spinning at high rpm (5250Rpm) Drive for booster - Normally @1450 rpm Type of impeller- Mostly preferred Double suction
Why is it important to maintain a gas-free condition in the boiler feed water?
Maintaining a gas-free condition in boiler feed water is crucial to prevent corrosion and scaling within the boiler system, which can lead to decreased efficiency and increased maintenance costs. Dissolved gases, especially oxygen and carbon dioxide, can cause pitting and other forms of corrosion in metal components. Additionally, gas bubbles can impair heat transfer, reducing the overall performance of the boiler. Ensuring the feed water is free of gases helps extend the lifespan of the boiler and improve operational reliability.
Why do you inject phosphate in boiler feed water?
Phosphate is injected into boiler feed water to control scale formation and corrosion inside the boiler system. Phosphate forms a protective layer on metal surfaces to prevent scale buildup and reduces the risk of corrosion, improving the overall efficiency and longevity of the boiler.
What is oxygen percentage in boiler feed water?
1ppb for O2 and CO2
