ASME Standard Carbon Steel Seamless Steel Superheater for CFB Boiler

ASME Standard Carbon Steel Seamless Steel Superheater for CFB Boiler

Superheater Arrangement, specification and material:

Arrnagement and specification:
The boiler has high and low superheaters, the HS is arranged in the flue gas duct after cyclone separators, and the LS is arranged in back-end vertical shaft. The saturated steam is introduced into the ceiling enclosure headers by eight φ108×5 saturated steam connecting tubes on the drum, and then into the lower temperature superheater through φ 42×4.0 tubes, after being heated by LS, goes into desuperheater for adjusting temperature, and then goes into HS through eight tubes of φ108×5, and sent to steam turbine through main steam valve after going into SH outlet header.
The LT superheater adopts contranatant arrangement and the HT superheater is downstream arrangement. The collection and distribution of steam adopts the way of width direction to improve non-uniformity of steam flowing and prevent local coils superheated due to steam deflection.

Material:
To ensure safety operation, the LT superheater uses SA210 Gr.A1 seamless steel tubes, and the HT superheater uses low-alloyed SA213 T22 seamless steel tubes.
