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 are the alternative dissolved oxygen scavengers other than hydrazine for hp boiler feed water?
Alternative dissolved oxygen scavengers for high-pressure boiler feed water include sulfite, carbohydrazide, and tannin-based products. These chemicals can effectively reduce dissolved oxygen levels in the water to prevent corrosion and damage to the boiler system. It's important to carefully choose the scavenger based on the specific requirements and operating conditions of the boiler.
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.
What is a function of deaerator?
deaerator is a device used to remove dissolved oxygen and carbondi oxide in boiler feed water. it causes scaling inside the boiler tubes and economizer also.
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.
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.
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
In boiler feed water line whether a non return valve should precede or succeed the delivery valve of feed water pump?
In boiler feed water line the NRV is normally installed between Pump and stop valve if the line is short and an another NRV is installed at boiler entrance and after stop valve if the line is long or pump is 10 to 15 m away from the boiler.
What has the author Percy George Jackson written?
Percy George Jackson has written: 'Boiler feed water' -- subject(s): Feed-water
What is the use of boilerfeed pump?
The boiler feed pump pumps hot feedwater into the boiler. The boiler pressure is to high for water to flow into it by gravity, so a pump is required.
