Detailed Information:

An Air Pre Heater (APH) tube is an essential component in air preheaters, which are heat exchangers used in industrial applications such as boilers, furnaces, and kilns. The primary function of an air preheater is to preheat the combustion air using waste heat from flue gases exiting the boiler or furnace. This preheating process enhances the system’s thermal efficiency by reducing the amount of usable heat lost in the flue gas.

Air Pre Heater Tubes are crucial in transferring heat from the hot flue gases to the incoming cold air. These tubes are typically made from high-quality materials using advanced manufacturing techniques to ensure durability and optimal performance. They come in various shapes, sizes, and specifications to meet the diverse requirements of different industrial applications.

The primary function of an air preheater (APH) is to capture and utilize the waste heat present in the flue gases as they exit a boiler. The air preheater tube is a vital component in this process, ensuring the efficient operation of the APH system.

To guarantee the performance and longevity of the APH system, these tubes must meet stringent requirements, including elongation, hardness, yield strength, and tensile strength.

APH Tubes are available in welded or seamless forms and can be hot-rolled or cold-drawn. The choice of APH ERW tubes depends on the boiler’s design, which is influenced by factors such as fuel type, operating temperatures, pressures, and steam volume requirements.

Air Pre Heater ERW Tubes are widely used across various industries, including power plants and process industries such as chemicals, sugar, power generation, steel manufacturing, cooling towers, superheaters, paper production, and air heating systems. Their reliability and efficiency are paramount in these applications.

Our top priority is ensuring our products meet and exceed industry standards for quality. Our APH Tubes undergo rigorous testing, including third-party inspections, PMI testing, raw material analysis, intergranular corrosion tests, pitting resistance assessments, and mechanical tests like flaring and flattening. This commitment to quality ensures that our products are reliable and perform optimally.

Types of Air Preheaters include:

  • Shell and Tube Type Single Pass Air Preheaters: Efficiently preheat combustion air in a single pass, optimising energy transfer.

  • Shell and Tube Type Dual-Pass Air Preheaters: Enhance heat exchange by allowing air to make two passes, improving energy efficiency.

  • Finned Tube Air Preheaters: Utilize finned tubes to maximise heat transfer capabilities, making them ideal for applications with stringent efficiency requirements.

Air Preheaters (APH) are indispensable for optimising performance in industrial heating and energy efficiency. Here’s how they work and why they are crucial:

APH units, typically designed with a shell and tube architecture, facilitate a remarkable transformation. Flue gases carrying valuable exhaust heat come into indirect contact with incoming air, enabling efficient heat exchange.

Anatomy of an Air Preheater:

The core of an air preheater is a shell containing an array of tubes arranged in a square or triangular configuration, expertly welded to a tube plate to ensure a robust structure. Depending on the specific requirements and maintenance needs, the arrangement can vary, allowing flue gases and air to traverse either the shell or tube sides.

Maximising Heating Surface Area:

At Thermodyne Boilers, we understand the importance of maximising heating surface area without compromising space. Our finned tube air preheaters are meticulously designed to increase efficiency by optimising heat transfer capabilities.

Custom-Built Solutions:

At Thermodyne Engineering Systems, we recognise that each project is unique. That’s why we offer custom air preheaters tailored to our customers’ specifications.

1 and 2 Pass Designs:

Our Air Preheaters come in both one-pass and two-pass designs. They ensure maximum heat extraction from flue gases, which is crucial for enhancing energy efficiency.

Versatile Fuel Compatibility:

We manufacture air preheaters designed to meet diverse fuel requirements, including wood, coal, husk, bagasse, petcoke, light, and heavy oil. This adaptability ensures our solutions align with your specific energy sources.

Benefits of Air Preheater Tubes:

  • Extract Maximum Waste Heat: A two-pass design allows us to harness the maximum waste heat from flue gases leaving the boiler, contributing to higher efficiency.
  • Improved Boiler Efficiency: By capturing waste heat from expelled flue gases, boiler efficiency sees a remarkable boost, often ranging from 2% to 3%.
  • Fuel Warming: Air preheaters also warm the incoming fuel, further enhancing the boiler’s overall effectiveness.
  • Faster Payback: The advantages of enhanced efficiency often translate into quicker payback periods, making them a wise investment.

Air Preheaters play a crucial role in maximising energy efficiency by converting waste heat into valuable resources. Thermodyne Boilers offers customised solutions and is dedicated to optimising performance, making them a reliable partner in achieving energy savings and promoting environmental sustainability.

Boiler APH Tubes Material Features

  • A corrosion-resistant material
  • A highly durable material
  • Free of leaks
  • Resistant to heat

Types Of APH Tubes

  • Single pass air pre-heaters of the shell and tube type
  • Dual-pass air pre-heaters of the shell and tube type
  • Pre-heaters for Finned Tubes

Working Of APH Tubes

When flue gases come into indirect contact with the air in an air preheater, which has a shell-and-tube design, the exhaust heat from the flue gases is transferred to the air as soon as they come into indirect contact.

The air preheater consists of a shell with various tubes arranged in a square or triangular configuration and welded to a tube plate. Pipestyles are different depending on the type of operation and the ease of cleaning, so flue gases may either enter the shell side or air may join the tube side.

By providing an increased surface area for the air heating coil, Hermodyne Boilers’ finned tube air preheaters improve efficiency and have a smaller footprint without requiring more space.

Depending on the customer’s specifications, Thermodyne Engineering Systems can manufacture a custom air preheater to meet their needs.

To maximize the amount of heat extracted from flue gases, our Air Preheaters are constructed in 1 and 2-pass designs.

A wide range of air pre-heaters is available from Thermodyne Boilers to meet a variety of fuel requirements, including:

  • Wood

  • Coal

  • Husk

  • Bagasse

  • Petcoke

  • Light Oil and Heavy Oil

APH Tubes Pros:

  • To capture the maximum amount of waste heat from the flue gases leaving the boiler, a two-pass design is used to convey waste heat from the flue gases leaving the boiler.
  •  Basically, it uses waste heat from the flue gases emitted from the boiler to generate electricity, significantly improving the boiler’s efficiency by 2% to 3%.
  • The boiler’s efficiency increases due to the warming of the fuel.
  • Payback time is shorter.

APH Tubes Cons:

  • There is a decrease in flue gas pressure caused by the addition of equipment or accessories that will increase the size of the induced draught fan as the pressure in the flue decreases.
