Types of Air Preheaters and Their Uses

There are two main types of air preheaters

  1. Regenerative Air Preheater: Designed with a rotating heat transfer surface, allowing flue gas to flow horizontally or vertically across its axis. It is commonly used in large industrial applications for efficient heat recovery.
  2. Plate or Tubular Air Preheater: Built into the boiler flue gas ducting, using plates or tubes to transfer heat from flue gases to incoming air.

Why Use Air Preheaters?

Air preheaters improve thermal efficiency by recovering heat from flue gases, reducing fuel consumption, operating costs, and emissions, while optimizing combustion processes.

Function of Corten (Core 10) APH Tubes in Boilers

  1. Energy Efficiency: By preheating the combustion air, Corten APH tubes reduce the amount of energy required to raise the air temperature to the desired level, improving the overall efficiency of the boiler system.
  2. Reduced Emissions: Corten APH tubes help lower flue gas temperatures, which in turn reduces the emission of pollutants, contributing to cleaner energy production.
  3. Fuel Savings: The improved efficiency of the boiler, driven by the use of Corten APH tubes, results in significant cost savings by lowering fuel consumption.

FAQs for APH (Air Pre-heater)Tubes

Air Preheaters (APH) are Shell and Tube Heat Exchangers that are used to heat the air before it goes into the boiler or furnaces/kilns to burn fuels. The main job of an air pre-heater is to take heat from the flue gases coming out of the boiler.

Air Pre-heaters are basically heat-exchangers installed in the exit flus gas duct of the boiler. The purpose of the air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by reducing the useful heat lost in the flue gas.

Core 10 APH tubes enhance boiler efficiency by preheating combustion air, reducing energy and fuel consumption. They lower flue gas temperature, minimize heat loss, and reduce emissions, promoting eco-friendly operation. These tubes optimize combustion, ensuring cost savings and improved performance, making them vital for efficient boiler systems in industrial applications.

The air preheater is positioned between the flue gas outlet (chimney) and the air inlet (economizer) in a boiler system. It reduces flue gas temperature from 400°C to 240°C, significantly enhancing boiler efficiency by up to 10%, optimizing energy use, and lowering operational costs.
