本文件提供了一套设计指南，旨在将大型煤粉锅炉的炉侧腐蚀、颗粒冲击侵蚀和蒸汽侧氧化对锅炉管道和其他部件的影响降至最低。特别强调先进超临界和超超临界锅炉中被认为风险最高的锅炉部件，即在金属表面温度高达约1350°F（730°C）的情况下运行的过热器和再热器管道。

This document provides a set of Design Guidelines aimed at the minimization of the effects of fireside corrosion, particle impact erosion and steam-side oxidation on boiler tubing and other components of large pulverized coal-fired boilers. Particular emphasis is placed on the boiler components considered to be at highest risk in advanced supercritical and ultra-supercritical boilers, i.e. the superheater and reheater tubing operating at metal surface temperatures up to approximately 1350°F (730°C).
