4.10.4 MSR reheater MSR 再热器
1. Reheater tube material shall be ferritic stainless steel. 再热管道材料应采用铁素体不锈钢。
2. Reheater tube bundle design and accuracy of manufacture shall be such as to ensure free thermal expansion of the reheater tubes under all conditions of operation without over-stressing or otherwise damaging the tube bundle frame. 再热器管束设计和制造精度应确保在所有运行条件下的自如热伸缩而不会出现过应力或其他方面的管束构架损伤。
Beijing Chinese Subtitling Translation Service Agency has translated many technical documents about MSR reheater. 华译网上海翻译公司曾经翻译过大量有关MSR 再热器资料文件。
3. Reheater tube supports shall be designed and spaced to prevent wear or damage due to aerodynamic, fluid elastic or any other type of vibration of the reheater tubing. 再热器管座的设计和位置间距,应能防止由于空气动力学、液体弹性、或任何其他类型的再热器管道振动所造成磨损和伤害。
4. The quantity of the reheater tubes shall have reasonable redundancy in case of individual tube plug requirement during MSR long-term operation. 鉴于在MSR长期运行中对个别管有堵管的需求,再热器管道的数量应有合理的裕度。
5. The performance of the reheat system shall be optimized recognizing the trade off of the reheated steam parameter between pressure drop and terminal temperature. 应考虑对压降和终端温度间的再热蒸汽参数进行权衡,使再热系统的性能达到最优化。
6. Supplier shall specify methods adopted to detect and deal with leaks of the reheater tubes, and to monitor the thermal condition of the tube bundle. 供方应规定探测和处理再热器管束泄漏、监测管束的热力状况所采用的方法。
7. Supplier shall provide outline of reheater tube plugging and tube bundle replacement procedures, complete with sketches showing method of plugging and replacing tube bundles, as well as checking to be carried out after plugging or replacing. 供方应提供再热器管束堵管和管束更换的程序概要,包括说明管束堵管和管束更换方法的草图,以及在实施堵管和更换后应进行的检查。
8. For bled reheating steam, methods shall be made to remove the moisture before the steam entering the bled reheater. 对于抽取的再热蒸汽,应提供在蒸汽进入抽汽再热器前去除湿气的办法。
