【摘要】 开发更大容量、更高压力和温度参数的机组,以进一步提高机组的经济性,降低机组单位造价,获得良好的性价比是超超临界机组发展的方向。探讨了1 200 MW超超临界参数锅炉的炉型选择、容量及参数确定,并针对其设计过程中的大容量断面的选取、高参数引起材料变化问题进行了研究分析。结果表明:对于1 200 MW的塔式锅炉,设计和制造技术均是成熟、可靠的。更多还原

【Abstract】 The USC unit development is trended to develop bigger capacity,higher pressure and temperature parameter units to further improve the unit economy,reduce the unit cost and obtain better performance to price ratio.The paper investigates 1 200 MW USC boiler model selection,capacity and parameter determination,and studies the following issues,like large section selection and material variation caused by high parameters during design process.The studied results indicate that design and manufacture technologies for 1 200 MW tower type boiler are mature and reliable.更多还原
