Flow Type

Classification by Flow Type

· The flow direction of combustion gas coincides with the flow direction of steam, and the hot part of the combustion gas and the low temperature part of the steam are in contact.
· The surface temperature rise of the tube is small, and the heat transfer efficiency is low.
· This type of superheater and reheater is installed in the high temperature part.

· The flow direction of the combustion gas and the flow direction of the steam are opposite, and the hot part of the combustion gas and the low temperature part of the steam are in contact.
· The surface temperature rise of the tube is large, and the heat transfer efficiency is high.
· This type of superheater and reheater is installed in the low temperature part.

· Mixed flow type is a combination of cocurrent type and countercurrent type and is mainly used for the final superheater and final reheater.

Linear Expansion Coefficient,
Design Pressure / Design Temperature

  • The coefficient of linear expansion of steel is 0.000011, and the expansion and contraction action occurs by 0.011mm per 1m according to 1℃ change in temperature. ( λ = coefficient of linear expansion × temperature difference × length = mm )
  • Design pressure
    – Operating pressure × 1.1
    – Operating pressure + 1.8 kg/cm2
    (select the larger of the two)
  • Design temperature
    Normal operating temperature + 10 ~ 20℃
    (In case of low temperature: operating temperature +0 ~ 10℃)
