SA192M Carbon Steel Economizer Coil for Sugar Mill Boiler Maintenance/Replacement
Description
A serpentine tube is a tube that twists and turns many times in a plane. The convection heating surface of the boiler, such
as economizer, superheater and reheater, mostly adopts the serpentine tube structure with horizontal and vertical layout.
The vertical coil is easy to accumulate water in the pipe after the boiler shutdown, but it is easy to support and hoist.
Differences
| Type | Advantages | Disadvantages | Supporting method |
| Pendant-type | 1.Firm structural support | 1. Flow blockage by condensed steam 2. Needs slow restart to purge the water that accumulates in the bottom. | supported from above |
| Inverted-type | 1.Proper drainage of the condensed steam | 1. Lack the structural rigidity, especially in high speed gas flow | Supported from below |
| Horizontal -type | 1. Proper drainage 2. Good structural rigidity. | 1. They do not view the flam directly so they are mainly from the convective type | Usually supported in the vertical gas ducts parallel to the main furnace. |
