Boiler Feed Water Management Concepts

The video tutorial explains the concept of boiler feed water, its importance in steam generation, and the necessity of treating it to remove impurities. It covers the process of blowdown to eliminate accumulated impurities and outlines the specifications that boiler feed water must meet to ensure efficient boiler operation. The tutorial emphasizes the role of high-quality water in preventing corrosion and maintaining boiler efficiency.

What are the two main components of a boiler?

• Pump and heat exchanger

• Radiator and valve

• Condenser and turbine

• Furnace and boiler proper

Why is high-quality water necessary for modern boilers?

• To prevent corrosion

• To increase fuel consumption

• To reduce steam production

• To enhance water hardness

What is the combination of return water and makeup water used for?

• To generate electricity

• To clean the boiler

• To cool down the furnace

• To feed into the boiler as boiler feed water

What is the purpose of the blowdown operation in a boiler?

• To add more fuel to the furnace

• To remove impurities from the boiler

• To decrease water temperature

• To increase steam pressure

What can cause poor heat transfer and reduced efficiency in a boiler?

• Low steam pressure

• High-quality water

• Dissolved solids forming deposits

• Excessive fuel consumption

What should the hardness of boiler feed water be below?

• 5 parts per million

• 10 parts per million

• 20 parts per million

• 2 parts per million

What is the acceptable range for caustic alkalinity in boiler feed water?

• 0.15 to 45 parts per million

• 10 to 50 parts per million

• 5 to 30 parts per million

• 1 to 20 parts per million

What should boiler feed water be free from to avoid forming?

• Organic matter, oil, and grease

• High temperature

• Oxygen and carbon dioxide

• Excessive pressure

In thermal power stations, where is feed water usually stored before being forwarded into the boiler?

• In the furnace

• In the condenser

• In the feed water tank

• In the steam turbine

What is the role of the boiler feed water pump?

• To heat the water

• To circulate water into the boiler

• To cool the steam

• To remove impurities
