Lord Fin Tube-H-type finned tube economizer

H-Type Fin Tube Waste Heat Recovery Device (Economizer)

The H-Type fin tube type waste heat recovery device, also known as an economizer, utilizes H-Type fin tubes (H-Type or double H-Type) arranged in an in-line configuration.

1. Replacement of Smooth Tube Economizer:

The economizer replaces traditional smooth tube economizers with H-Type fin tube economizers, increasing the heat exchange area while reducing the number of tubes. This arrangement allows for a larger cross-section for flue gas flow, reducing velocity and wear. The finned tubes concentrate fly ash towards the middle of the tube row, minimizing structural wear.

2. Structure and Performance of H-Type Finned Tubes:

   a) H-Type Finned Tube Structure: The basic forms are "H" and double "H" types arranged in-line.

   b) Increased Rigidity: H-Type finned tubes can be designed as double-tube "double H" configurations, providing enhanced structural rigidity suitable for long tube rows.

   c) Uniform Airflow and Reduced Wear: H-Type finned tube economizers arranged in series divide the space into smaller areas, ensuring a uniform flow effect on the air and significantly reducing wear.

   d) Improved Soot Blowing: The straight channels formed by the H-shaped fins facilitate effective soot blowing.

   e) Compact and Lightweight: The economizer has a compact design, resulting in reduced overall weight and cost.

3. Energy Efficiency and Low Power Consumption:

   a) Heat Loss Reduction: The use of an economizer in a generator set can reduce the heat loss in generator exhaust by at least two-thirds.

   b) Low Electricity Consumption: The H-Type finned tube economizer consumes only 2 to 4 kW of electricity per ton of steam.

4. Simple Operation and Maintenance:

The economizer is pre-assembled and shipped from the factory with a simple structure and few moving parts. This design facilitates easy installation and reduces labor requirements.
