spares parts bare tube air preheater for boiler heat exchanger

2025 New condition boiler enamel tube air preheater with ASME standard is the equipment that uses the boiler tail flue smoke to heat the entering air with its inside tubes .It is used to improve the heat exchange performance of the boiler, and reduce energy consumption.

2025 New condition boiler enamel tube air preheater with ASME standard is a general term used to describe any device designed to heat air before another process (for example, combustion in a boiler) with the primary objective of increasing the thermal efficiency of the process. They may be used alone or to replace a recuperative heat system or to replace a steam coil.

Features of tubular air preheater

1. 2025 New condition boiler enamel tube air preheaters with ASME standard are not easily broken enamel surface, no crack, acid and alkali resistance, resistance to gas erosion, smooth and high, gas flow resistance, easy Fouling;
2. As the flue gas across tube, the flue gas side of the heat capacity of exile to strengthen, under the same heat transfer coefficient (enamel thickness ratio of thermal conductivity with very small, about 0.0002, the calculation is negligible), wall temperature vertical preheater than ordinary steel increased 10-30 Degree Celsius, the overall heat transfer coefficient of about 20.3-24.2W;
3. Two horizontal enamel sealing tube box, the sealed tube box structure welded high strength, pipe damaged or the overall change can only block, and heat-packing seal, can only replace the damaged pipe tube, easy maintenance;
4. 2025 New condition boiler enamel tube air preheater with ASME standard is mainly used for boiler preheater, the low temperature.

Specifications of tubular air preheater

1.High corrossion resistance proerty;
2.Small covering area;
3.Pipe and tube plate in every link between separated, the heated bilges cold heat distortion is not bound to avoid stress destruction;
4.Single pipe, tube single or parts of equipment failure does not affect the heat normal operation
