US 2025/0128206 A1 · SEAL STRUCTURE, HEAT RECOVERY STEAM GENERATOR, AND FLUE GAS SEALING METHOD

Abstract

There are provided a thermal barrier coating material and a thermal barrier coating member that can suppress spalling when used at a high temperature and have a high thermal barrier effect, a method for producing the same, a turbine member coated with a thermal barrier coating, and a gas turbine. The thermal barrier coating member comprises a heat resistant substrate, a bond coat layer formed thereon, and a ceramic layer formed further thereon, wherein the ceramic layer comprises an oxide which consists of an oxide represented by the general formula A2Zr2O7 doped with a predetermined amount of CaO or MgO and has 10 volume % or more of a pyrochlore type crystal structure, where A represents any of La, Nd, Sm, Gd, and Dy.

Dependent claims

A seal structure configured to seal a gap formed between a duct in which a flue gas flows through and a flue gas denitrizer arranged in the duct, the seal structure comprising:

at least one duct-side seal part fixed to the duct and arranged in the gap;
a flue gas denitrizer-side seal part fixed to the flue gas denitrizer, arranged in the gap, and abutting against or being close to the duct-side seal part;
and
a first catalyst seal part fixed to the flue gas denitrizer, arranged in the gap, and configured to push the duct-side seal part against the flue gas denitrizer-side seal part,
wherein the first catalyst seal part is formed of a denitration catalyst.
