🔥 Tubular & Rotary Air Preheaters (Preheating Air to 250°F / 1% Eff per 40°F)

Boiler Combustion Air Preheater Calculator

Size tubular and heat-pipe combustion Air Preheaters (APH) for large industrial water-tube boilers and process heaters: calculate combustion air intake flow (SCFM), thermal heat duty transferred from flue gas to intake air (raising air to 200°-300°F providing 1% boiler efficiency boost per 40°F air temp rise), and boiler equipment margins.
