Heat pipe air preheater
Heat pipe air preheater was made up of collecting header, heat pipe tube bank and compartment. Heat pipe tube bank was separated into smoke channel and air channel by compartment.
1. The smoke and air was separated by compartment, good welding sealing for heat pipe wait and middle compartment, air is unable enter into flued.
2. Through adjustment heat transfer eare of heat pipe, for controlling wall temperature higher than smoke dew point, prevent acid corrosion effectively.
3. Adopt high frequency screw electrical resistance weld sheetmetal force heat transfer, big heat transfer ratio, long service life. Flued not have corner pocket, little resistance of smoke .
4. Can get the profit in 4-6months after investing equipment.
