Structure design advantages
1. Three pass structure.
Function: ectend the flow of smoke and enhance the heat transfer.
2. Water-fire tube type.
Function:Fire tube:the flue goes through furnace, wing-shape flue
and fire tubes to form three pass as said in the above.Water tube:
water in some tubes rises after heating and some declines, which
forms a natural circulation.
3. Spirally corrugated tube
Function:heat transfer enhancement, reduce the spirally corrugated
tube numbers, and improve the suppleness to avoid the tube plate
cracking.
4. Arched tube plate
Function:reduce the thermal stress of weld and improve the tube
plate suppleness,meantime, simplify the structure and save the
boiler room space.
5. Wing-shape flue.
Function:reduce the smoke temperature of high temperature tube
plate to slow down subcooled boiling. In this way, it can prevent
tube plate cracking, reduce heat load of boiler bottom and prevent
bulge.
6. Simple circulation loop, large sized down pipe and bottom
container.
Function: Prevent tube explosion , increase the reliability of
water circulation ,avoid deposition of debris and dirt,reduce fuel
consumption and improving the operating time of boiler.
