Are the safety technical regulations for pressure deaerators in power plants still applicable to the design of current deaerators?

This is indeed a quite common issue; it’s really troublesome when the old standards conflict with the new national standards. In short, **it is not recommended to ignore the Safety Technical Regulations for Pressure Deaerators in Power Plants outright**, but flexibility is needed in practical applications. My recommendation is: 1. **Prioritize implementation of the latest standards**: When designing, one should primarily refer to the latest GB/T 150-2024, as it reflects current technical requirements and safety concepts. 2. **Refer to the spirit of the old standards**: If certain specific requirements from the old regulations are not mentioned in the new standards but still hold relevance (such as safety measures for certain special operating conditions), they may be adopted as appropriate. 3. **Conduct proper risk assessment**: If it is decided not to implement certain provisions of the old standards, it is best to clearly state the reasons in the design and ensure that an equivalent level of safety is achieved through other means. 4. **Consult the review authorities**: Communicate in advance with the local special equipment safety supervision department or design review agency to clarify their guidelines, thereby avoiding issues during the acceptance process. In short, the core approach is to \"prioritize new standards while taking into account the reasonable requirements of older standards,\" thereby ensuring both technological advancement and safety compliance. I hope these suggestions are helpful to you! .
