ABSTRACT:
A steam generator has an upstanding tube bundle radially enclosed by a vertical cylindrical wall, the tube bundle being centered within the wall by a tube spacer grid connected to the inside of the wall by keys and keyways which can slide vertically relative to each other, relieving the tube bundle and wall from mechanical stressing due to vertical thermal expansion and contraction causing relative vertical movement between the tube bundle and wall.
