摘要: 隨著超臨界/超超臨界火力發(fā)電機(jī)組蒸汽溫度和壓力的提高,對鍋爐所用關(guān)鍵材料鍋爐鋼管的性能提出了更高的要求,而材料標(biāo)準(zhǔn)和技術(shù)條件是材料應(yīng)用的載體,對照ASME標(biāo)準(zhǔn)可以看出,我國鍋爐鋼管標(biāo)準(zhǔn)在標(biāo)準(zhǔn)體系、標(biāo)準(zhǔn)水平和新材料納標(biāo)上存在很大差距;建立完善的、適合我國國情的鍋爐鋼管標(biāo)準(zhǔn)體系,提高標(biāo)準(zhǔn)水平,促進(jìn)新型鍋爐用鋼管的國產(chǎn)化,是鍋爐鋼管標(biāo)準(zhǔn)今后發(fā)展的主要方向之一,也是我國超臨界火力發(fā)電機(jī)組發(fā)展的關(guān)鍵所在。Abstract: Following higher steam temperature and pressure as required for the supercritical and ultra-supercritical generation sets of thermal power plants,the requirements for properties of steel boiler pipes acting as key materials for the boiler are more stringent.And the standard and technical conditions of the materials are the carrier of application thereof.Compared with relevant ASME standard,there exists a huge gap between the ASME standard and the domestic boiler pipe standard in terms of standard system,standard level and standardization of new materials.Therefore,it is concluded that one of the major possible development orientations of domestic steel boiler pipe standard is to establish complete domestically-applicable standard system for boiler service steel pipes,to enhance standard level and to promote the localization of new type boiler-purpose steel,which is also very important to the development of home-made supercritical thermal power generation sets.
