摘要
A steam duct (5) enclosing the preheater tube-bundle (6) leads, upwards, from the desuperheater box (2) and via a deflecting quarter-bend (9), opens into a flat steam-distribution duct (8). The heating steam flows from this distribution duct (8), through steam outlet openings (12) on the vertical narrow sides (11), and thereafter flows radially through the preheater tube-bundles (6), from the outside to the inside.
