Composite ceramic heat exchange tube

摘要: The heat exchange tube has a porous thermal shock resistant outer shell composed of corrosion ceramic material that may have finned surface or plain cylindrical surface. contains an inner dense nonporous which is capable containing high pressure gases, but not be as thermally the shell. formed such highly silicon carbide nitride having at each end like density insert. inserts provide sealing surfaces to contact other components in exchanger identical assemblies form gas-type seal. can fabricated by deposition technique chemical physical vapor deposition, and alternatively, made separately press fitted into cast otherwise around tube. As alternative solution, seals integrated single component performing functions all three components, i.e., two
