Description

technical field

[0001] The invention belongs to the technical field of boiler component structures, and in particular relates to a U-shaped tube superheater. Background technique

[0002] The horizontal flue of a horizontal waste incineration boiler is usually arranged with a vertical convection superheater, such as Figure 5 with Image 6 As shown, there are two common types of superheaters: serpentine tube superheater and tube row superheater.

[0003] Figure 5 Shown is the serpentine tube superheater, when the top of the horizontal flue is equipped with a membrane water cooling wall, the serpentine tube superheater needs to pass through the top water cooling wall. Therefore, the pitch of the serpentine tube is restricted by the pitch of the top water wall, which has a great influence on the heat transfer and dust accumulation of the superheater. If there is no membrane water wall on the top of the horizontal flue, it is necessary to install the top guard plate and pour...
