前言近几年来,日本石川岛播磨重工业公司为了达到提高火电设备效率的目标,力求建造更高参数的超高温高压设备,故制定了如表1所示的开发步骤。要使这些蒸汽参数达到超高温高压就必须采用新材料。处于锅炉最苛刻条件下工作的过热器管和再热器管材料的选择,可以说是实现超高温高压锅炉的最重要课题。选择这些材料时要考虑其高温强 Preface In recent years, Japan Ishikawajima Broadcasting Heavy Industries Co., Ltd. in order to achieve the goal of improving thermal power equipment efficiency, and strive to build a higher parameters of ultra-high temperature and high pressure equipment, so developed as shown in Table 1 development steps. New materials must be used for these ultra-high temperature and high pressure steam parameters. The choice of superheater tubes and reheater tubes that work in the most demanding conditions of the boiler can be arguably the most important topic for achieving ultrahigh temperature and pressure boilers. When choosing these materials, consider their high temperature
