Air Preheaters

Air Pre-heaters are the heat-exchangers, which are fitted in the exit flus gas channel of the cistern. The function of these is to recuperate the heat from the boiler flue gas so as to boost the boilers thermal efficiency. These can also reduce the heat loss. They are responsible for boosting the efficiency of the steam boiler. Advantages include low payback time, enhanced stability, right combustion of poor-quality fuels, good heat transfer rate and reduced heat transfer area. Air Pre-heaters can raise the temperature of the furnace gases, boost combustion efficiency and combustion rates. These are known well for improving the overall efficacy of the boiler.

Key Points:

Reduced number of unburnt fuel particles.

High combustion efficiency

Increased efficiency of boiler by 2 to 3 %.

Heat transfer rate is high.

FAQs of Steam Coil Air Preheaters:

Q: How do Steam Coil Air Preheaters improve industrial heating efficiency?

A: Steam Coil Air Preheaters enhance efficiency by utilizing steam to preheat air entering process equipment, thereby reducing fuel consumption and improving thermal transfer rates. Their advanced fin designs and customizable heat transfer areas enable high efficiency (up to 90%) tailored to various industrial requirements.

Q: What materials are available for the coils and fins, and how do I choose the right one?

A: Coils can be manufactured from carbon steel, stainless steel, or copper alloys, while fins come in aluminum, copper, or stainless steel. Choice depends on application-specific factors such as operating temperature, pressure, corrosion conditions, and required thermal conductivity.

Q: When should I specify customized options for a Steam Coil Air Preheater?

A: Customization is advisable when standard solutions do not fit your thermal load, spatial constraints, or process integration. Projects with unique temperature, pressure, size, or corrosion resistance needs will benefit from tailored tube thickness, heat transfer area, and connection types.

Q: Where can these preheaters be installed, and what orientation is suitable?

A: These units are versatile and can be installed in horizontal or vertical orientations, depending on space availability and process flow. Common installation sites include power plants, HVAC systems, refineries, and chemical processing plants.

Q: What is the process for surface treatment and why is it important?

A: Surface treatment involves applying anti-corrosive coatings or specialized paints to protect metal components against oxidation, chemical attack, and moisture. This process increases lifespan and ensures sustained efficiency in harsh or corrosive environments.

Q: What are the primary usage scenarios for these air preheaters?

A: They are widely used in industrial heating, ventilation, and air conditioning, as well as in power generation, chemical industry, and petroleum refining. Their ability to handle high steam pressures and large airflow rates makes them suitable for heavy-duty thermal management applications.

Q: What certifications and testing ensure the reliability of Steam Coil Air Preheaters?

A: Each unit undergoes hydrostatic and pneumatic testing to certify its integrity under pressure. ISO certifications or other client-specified standards are also available, ensuring adherence to stringent quality and safety protocols.
