H-Type Finned-Tube Economizer Overview

The H-type finned-tube economizer is a high-efficiency heat exchange component assembled with H-type finned tubes, also known as butterfly tubes. Below are the key specifications, characteristics, and applications of this economizer:

H-Type (Square) Finned Tube Specifications:

- Dimensions: 32*4, 32*5, 38*4, 38*5, 42*5, 48*5, 51*5, 51*6, etc.

- Pipe Diameters: 25~65, wall thickness greater than 3 mm.

H-Type (Square) Finned Tube Material Options:

- Carbon steel, stainless steel, ND steel, alloy steel, and more.

H-Type (Square) Finned Tube Structure:

1. Basic Forms: "H" and double "H" types, arranged in line.

H-Type (Square) Finned Tube Performance Characteristics:

1. Increased Heat Exchange Area:

   - Replacing bare tube economizers with H-type finned tubes increases the heat exchange area, reducing the number of tubes needed and optimizing flue gas flow.

2. Reduced Flue Gas Velocity and Wear:

   - The arrangement of finned tubes decreases flue gas velocity, reducing wear. Finned tubes centralize fly ash, further reducing wear.

3. Structural Rigidity:

   - Double-tube "double-H" type finned tubes provide structural rigidity, suitable for long tube rows.

4. Equalized Airflow:

   - H-type fins divide the space, equalizing airflow and minimizing wear.

5. Soot Blowing Efficiency:

   - H-type fins create straight passages on both sides, optimizing soot blowing.

6. Compact and Lightweight:

   - Compact design reduces overall weight, leading to cost savings.

7. Energy Efficiency:

   - Significant reduction in heat loss, consuming only 2-4 kW of power per ton of steam, resulting in energy savings.

8. Simple Operation and Maintenance:

   - Assembled as a whole, fewer moving parts, simple structure, easy installation, and high automation levels contribute to simplified operation and maintenance.
