Coal-Fired Boiler - an overview | ScienceDirect Topics

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C ( Shen and Cheng 2004 ).

Locomotive Boiler: Definition Parts Working Principle ...

Flues or Tubes: A large part of the locomotive boiler is composed of flues or tubes. The flues give to the boiler the largest part of its heating surface.tubes are made up of carbon molybdenum steel 18-8 Cr Ni steel.. It is the flues that largely affect the life of the boiler and that why it is the life of the locomotive for this reason it is quite necessary to properly install and maintain ...
