摘　　要：新疆地区某350 MW超临界自备机组拟对外进行供汽,以实现经济效益最大化。由于该机组燃用准东煤,锅炉运行参数与原有设计值存在偏差,较常规抽汽改造具有其特别之处。通过结合现有运行工况根据所需供汽参数提出不同抽汽方案并进行对比分析,以供电厂进行选择。Industrial steam supply is scheduled to be carried out for maximized benefits on a 350 MW ultra-supercritical unit in Xinjiang district. Deviations are found in the actual operational data from the original design as the unit fires Zhundong coal, which presents specialties from other conventional units. Different steam extraction schemes are put forward with their comparisons and analysis to provide choices for power plants.
