1. Classification by structural type
The fin tube can be divided into two basic types: longitudinal type and radial type. Other types are the development and deformation of these two types. For example, the shape of large helix angle fin tube is close to the longitudinal type, and the shape of small helix angle fin tube is close to the radial fin tube has circular, rectangular and needle shape. In addition, the fins can be arranged outside the tube, which is called the outer fin tube, or inside the tube, which is called the inner fin tube or both.

Specifications
1). Add the heat exchange area and reduce the number of tubes, also increase the fume flow section area to reduce the fume speed and abrasion.
2). H type fin tube can be made to double H type fin tube, high rigidness to fit long tube row.
3). H type fin economizer arranged in line to make the space into many small zones, averaged air flow to reduce the abrasion.
4). With straight channel to gain the best ash-blowing effect.
5). The compact structure to reduce the weight and reduce the manufacturing cost.
