Summary:The utility model relates to a desuperheater for a boiler reheater, in particular to a secondary desuperheater protection system for an ultra-supercritical boiler reheater. A secondary desuperheater of an existing large boiler reheater is lack of failure protection. the problem of thermal fatigue failure is easy to occur; the utility model provides a secondary desuperheater protection system for an ultra-supercritical boiler reheater. The temperature reducing device comprises a temperature reducing water pipeline and a secondary temperature reducer, the desuperheating water pipeline is connected with an inlet pipeline of the secondary desuperheater; the secondary desuperheater is characterized in that the desuperheating water pipeline is connected with an inlet pipeline of the secondary desuperheater and the desuperheating steam pipeline through a tee joint; the far end of the temperature reducing steam pipeline is connected with a steam source and extracts steam, the temperature of the temperature reducing s
