Analysis and Study on Influence of Separator Separation Efficiency to Boiler Operating Parameters

介绍了300 MW循环流化床锅炉分离器提效改造技术及分离器分离效率提高后对锅炉运行参数的影响分析研究,研究发现分离器改造后各负荷工况下一次风量、稀相区压力、床下部温度、排烟温度、污染物原始排放值等参数均发生了趋势性的变化,从多参数、多工况角度进行了全方面的阐述和分析研究,结论认为分离器效率提高后对锅炉安全、经济运行的影响是正向的,为其它同类型机组技术改造提供了借鉴。

The analysis and study of the effect to 300MW circulating fluidized bed boiler operating parameters after the efficiency of separator is improved through technological transformation, and it is found that the primary air volume,dilute phase pressure, bed temperature, exhaust temperature, pollutant original emission value and other parameters of each load after the transformation of the separator have undergone trend changes. The impact of economic operation is positive, providing a reference for the technological transformation of other units of the same type.
