HORIZONTAL LOAD TRANSFER STRUCTURE OF HEATING TUBE IN HEAT RECOVERY STEAM GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide a horizontal load transfer structure of heating tube in a heat recovery steam generator, in which miniaturization and weight reducing are attained in a member, which receives a horizontal load acting on the heating tubes and transfers to the casing, surface-temperature increase of the casing is suppressed, effect of a heat strain can be suppressed, and insulation is improved to increase the efficiency.;SOLUTION: Load transfer metal fittings 24 are attached to necessary important positions in the lateral direction of tube-nest plates 20. The horizontal loads acting on heating tubes 3a, 4a and 5a are received from the plates 20 through the metal fittings by short-pass-preventing plates 22, and transferred to the casing 12.;COPYRIGHT: (C)2002,JPO
