Air Pre Heaters
Enmax Air Pre Heaters (APH) are advanced tubular or finned-tube heat recovery systems designed to preheat combustion air using hot boiler exhaust flue gases. Preheating the air significantly raises combustion temperatures, enhances fuel burning efficiency, and yields substantial coal or fuel savings.
Our APH designs are custom-built to minimize corrosion from cold-end condensation by using corrosion-resistant materials such as Corten steel or glass tubes. Engineered for high reliability and ease of maintenance, they fit seamlessly into boiler exhaust ducts and conform to ASME and local IBR regulations.
