文摘
- •
Trisection helical baffles are introduced for vertical condenser enhancement.
- •
Condensation in short-section and intermediate drainage is applied in new schemes.
- •
Helical baffles with liquid dam and drainage gaps can promote condenser performance.
- •
Dual-thread baffle scheme is superior to that of single-thread one by about 19%.
- •
Condensation enhancement ratio of helical schemes is 1.5–2.5 over segment one.
