Environmental energy efficient Regenerative Air Preheater (APH) heat preservation With ASME Standard
Description
After flue gases leave economiser,some further heat can be extracted from them and used to heat incoming heat.Cooling of flue gases by 20 degree centigrade increases the plant efficiency by 1%.
The purpose of the air preheater is to recover the heat from the flue gas(exhaust gases) from the boiler to improve boiler efficiency. Incidentally the gases are sent to the chimney or stack at lowered temperature so that the design of the ducting and the stack becomes simplified. Also it controls the temperature of gases coming out of the stack.

High efficiency and energy saving boiler part air preheater 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.
Specification
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
Features
1. As the flue gas across tube, the flue gas side of the heat capacity of exile to strengthen, under the same heat transfer coefficient, wall temperature vertical preheater than ordinary steel increased 10-30 Degree Celsius, the overall heat transfer coefficient of about 20.3-24.2W;
2. Two horizontal 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.
3. The tube air preheater is mainly used for boiler preheater, the low temperature.
