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:

Economizer: Preheats feedwater using low-temperature exhaust gas (250–350°C), improving thermal efficiency.
Evaporator: Absorbs medium-grade heat (300–400°C) to convert water into saturated steam.
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).
