In the industrial world, the boiler system is an important component in the process of heating water or producing steam for various production purposes. This system is widely used in various sectors such as manufacturing, food and beverage, textiles, petrochemicals, and power plants. However, behind its crucial function, the boiler system also holds potential risks if not properly maintained, especially related to the quality of the water used in it.
What is a Boiler System?
A boiler system is a system designed to produce steam or hot water by heating water using heat energy, usually from fuels such as gas, oil, or coal. In the context of water treatment, boilers are used to provide steam as a heating medium in various production and sanitation processes.
Boilers not only function as heating devices, but also as systems that must work efficiently and safely. Minor problems such as scale, corrosion, and water contamination can cause decreased efficiency, increased operational costs, and even serious damage to the system as a whole.
Main Components in a Boiler System
Understanding the important parts of a boiler system will help in its management and maintenance. The following are the main components in a boiler system:
1. Burner
The burner functions to mix fuel and air, then burn it to produce heat. Burner efficiency greatly affects the overall performance of the boiler.
2. Combustion Chamber
This chamber is where the combustion process occurs. The heat generated here is used to heat the water flowing in the boiler pipes.
3. Heat Exchanger
This component allows heat transfer from the combustion results to water or other working fluids without direct contact between the fuel and water.
4. Boiler Drum / Steam Drum
A steam drum is a tank used to store steam and water that has been heated. This is where the separation between steam and water occurs.
5. Feedwater System
This system is responsible for supplying water to the boiler. The quality of the water at this stage is very important to prevent the formation of scale and corrosion.
6. Blowdown System
Blowdown is the process of removing water from the boiler to control the concentration of dissolved solids and prevent scale deposition.
7. Control System (Automatic Control System)
Modern control systems regulate various parameters such as pressure, temperature, and water and fuel flow rates to ensure stable boiler performance.
8. Safety Valve and Pressure Gauge
These components are very important in maintaining system safety. The safety valve prevents excess pressure, while the pressure gauge helps monitor pressure in real time.

Common Boiler System Problems
Boiler systems are very sensitive to changes in water quality. Some common problems that often occur include:
1. Scaling
- Occurs when minerals such as calcium and magnesium settle on the inner surface of the boiler.
- Reduces heating efficiency and increases energy consumption.
- If left untreated, scale can cause overheating and even permanent damage.
2. Corrosion
- Caused by oxygen and carbon dioxide dissolved in water.
- Results in metal damage and pipe leaks.
- Requires control through proper chemical treatment.
3. Foaming and Priming
- Foaming is the formation of foam on the surface of the boiler water which can cause steam contamination.
- Priming occurs when water is carried along with the steam, disrupting process quality and endangering downstream systems.
4. Carryover
- The process where impurities are carried along in the steam stream due to unstable operating conditions.
- Can damage equipment such as turbines or heat exchangers.
