Description

HFW Finned Tube Serrated Type SA387 Grade 12, 13CrMo4–5 Fins for Power Plant HRSG


An HRSG (Heat Recovery Steam Generator) comprises three core sections:

  1. ​​Economizer​​: Preheats feedwater using low-temperature exhaust gas (250–350°C), improving thermal efficiency.
  2. ​​Evaporator​​: Absorbs medium-grade heat (300–400°C) to convert water into saturated steam.
  3. ​​Superheater​​: Elevates steam temperature to 500–600°C using high-grade heat, ensuring dry, high-energy steam for turbines.

HRSG Tube Types, Parameters, and Functions​

Tube Type​​ ​​Key Parameters​​ ​​Function​​
​​Economizer​​ - OD: 25–50 mm
- Temp: 250–350°C
- Pressure: 5–15 MPa		 Preheats feedwater using exhaust gas, improving thermal efficiency.
​​Evaporator​​ - OD: 30–60 mm
- Temp: 300–400°C
- Pressure: 10–20 MPa		 Converts water to steam via heat absorption from flue gas.
​​Superheater​​ - OD: 25–50 mm
- Temp: 500–600°C
- Pressure: 15–25 MPa		 Increases steam temperature above saturation for turbine efficiency.
​​Serrated Fins​​ - Height: 12–25 mm
- Thickness: 1–2 mm
- FPI: 3–7		 Enhances heat transfer via turbulence and surface area (used in all sections).
