What Is Boiler And Its Classification?
Boiler is a closed vessel in which water or other fluid is heated under pressure to produce steam or hot water. Boilers are used for various applications like power generation, industrial processes, and space heating.
- Fire Tube Boilers - Hot gases from the furnace pass through tubes submerged in water. The tubes are surrounded by water, and the heat is transferred through the tube walls.
- Water Tube Boilers - Water flows through tubes surrounded by hot gases, producing steam or hot water.
Problems in Boiler
The three major problems in boilers are:
Scaling and Corrosion: Can lead to reduced efficiency and equipment failure.
Boiler Water Carryover and Priming: Can damage steam turbines and other equipment.
Corrosion in Boilers Includes
These issues can lead to reduced efficiency, increased energy costs, equipment damage, and even safety hazards. Regular monitoring and maintenance can help prevent or address these problems.
- High Oxygen Concentration
- High or low pH levels
- Scaling and Fouling
- Water Hammer and Vibration
- Incorrect Fuel-to-Air Ratio
- Poor Maintenance and Neglect
- High Temperatures
- Corrosion and Pitting
- Insufficient Water Treatment
- Clogged or Faulty Burners
Solutions
Here are three chemical products commonly used to treat boilers:
These chemicals help maintain boiler efficiency, prevent damage, and ensure safe operation.
- Alkalinity Builders (e.g., sodium hydroxide, sodium carbonate) to maintain optimal pH levels.
- Our Products: ECHO CHEM – B – 140, ECHO CHEM – B – 190
- Oxygen Scavengers (e.g., hydrazine, sulfite) to remove dissolved oxygen and prevent corrosion.
- Our Products: ECHO CHEM – B – 140, ECHO CHEM – B – 190
- Scale Inhibitors (e.g., phosphonates, polymers) to prevent mineral deposits and scaling.

Descaling Chemicals
Descaling chemicals are substances used to remove mineral deposits and scale buildup in boilers, heat exchangers, and other equipment. They dissolve and break down calcium carbonate, lime, and other deposits. Common descaling chemicals include hydrochloric acid, sulfuric acid, and citric acid.

Boiler Antiscalant / Boiler Phosphate Treatment Chemicals
Sludge conditioners are chemicals that prevent, soften, and disperse sludge deposits, facilitating removal through blowdown. They maintain clean heat transfer surfaces, reduce corrosion, and ensure efficient boiler operation.
