330MW亚临界锅炉深度调峰背景下提高准东煤掺烧比例的方案研究

Research on Scheme of Increasing the Blending Proportion of Zhundong Coal on 330 MW Subcritical Boiler with Depth Peak Loading

以某电厂330 MW亚临界机组为研究对象,通过设备改造及燃烧调整,在掺烧准东煤的条件下锅炉实现低负荷稳燃及深度调峰,探究大比例掺烧准东煤工况下锅炉的抗结焦性、稳燃特性、经济性及环保特性。以期锅炉在深度调峰环境下达到最为理想的燃烧状态。

Taking a 330 MW subcritical unit of a power plant as the research object,with equipment retrofit and combustion adjustment,the boiler achieves low load stable combustion and deep low load under the condition of mixing Zhundong coal.The anti-slagging,stable combustion,economy and environmental protection characteristics of the boiler with large proportion of mixing Zhundong coal are studied in order to achieve the most ideal combustion state of the boiler in the deep peak loading environment.
