【摘要】 与传统的一次再热机组相比,采用二次再热能够进一步提高机组的热效率,并满足机组低压缸最终排汽湿度的要求。开发更为高效环保和具有自主知识产权的二次再热超超临界锅炉是我国电力工业的重要发展方向。介绍了开发大容量超超临界二次再热发电机组的必要性,提出了锅炉设计的初步设想和方案,为填补我国在超超临界二次再热机组上的空白作出努力。更多还原

【Abstract】 Compared with traditional single-reheat unit, the thermal efficiency of double-reheat unit is further improved and the wetness requirement of exhaust steam in its low-pressure cylinder can be satisfied. To develop high-efficient and environment-friendly double-reheat ultra-supercritical boiler with proprietary intellectual property rights is an important development direction in our power industry.The necessity of developing large-capacity ultra-supercritical double-reheat unit is proposed, while corresponding preliminary ideas and solutions for boiler design put forward, which makes an effort for filling the gap of our country in the ultra-supercritical double-reheat power generation unit.更多还原
