Feed Water Tank for Industrial Steam Boiler Systems
What Is a Feed Water Tank?
A Feed Water Tank is a storage vessel used to collect and hold treated make-up water and condensate return before it is supplied to the boiler through feedwater pumps.
The tank is designed according to boiler capacity, feedwater requirement, operating temperature, storage capacity, and overall boiler system configuration.
Why Is a Feed Water Tank Important?
A steam boiler requires a consistent supply of properly treated feedwater for reliable steam generation. The Feed Water Tank provides buffer storage between the water treatment/condensate recovery system and the boiler feed pump, helping manage variations in feedwater demand.
Maintaining the appropriate feedwater temperature can also support efficient boiler operation and reduce thermal stress when water enters the boiler.
How to Select a Feed Water Tank?
The Feed Water Tank should be selected based on the complete boiler system design. Important factors include:
- Boiler capacity
- Feedwater consumption
- Required storage capacity
- Condensate return quantity
- Feedwater temperature
- Make-up water requirement
- Feedwater pump capacity
- Material of construction
- Tank dimensions and available space
- Applicable design and safety requirements
How Does a Feed Water Tank Work?
1. Treated make-up water and recovered condensate enter the feed water tank.
2. The water is collected and maintained at the required level.
3. Heating may be provided to maintain the desired feedwater temperature.
4. Feedwater pumps draw water from the tank.
5. The pumps supply the feedwater to the boiler for steam generation.
6. The cycle continues according to the boiler’s water and steam demand.
Key Functions of a Feed Water Tank
- Stores treated boiler feedwater
- Collects and manages condensate return
- Provides a reliable water source for feedwater pumps
- Helps maintain required feedwater temperature
- Supports continuous boiler operation
- Helps accommodate fluctuations in boiler water demand
- Integrates with condensate recovery and water treatment systems
- Supports efficient and reliable steam generation
