Mineral conversion and thermodynamic simulation of ash deposition during Zhundong coal combustion in boiler of thermal power plant

Funds: The project was supported by the National Basic Research Program of China (973 Program, 2012CB214906).
  • 摘要: 选取某350 MW电站锅炉燃烧准东混煤,得到锅炉换热面灰沉积样品,主要借助XRD等手段分析了各处灰沉积物矿物形成过程,并通过Factsage 5.2从热力学平衡角度给出理论支持。结果表明,高温区域换热面灰沉积形成主要由于钠长石、钙长石等矿物在高温下经复杂变化形成低温共熔物,黏附烟气中固体颗粒而形成坚硬块状沉积物;低温区域换热面主要由于烟气中硫的沉积而发生酸性腐蚀,沉积物主要晶相为硫酸钙;省煤器换热面主要由于烟气携带的非晶态物形成松散型积灰。Factsage计算结果与实际灰样组成大致吻合,能够帮助分析灰沉积物中矿物质的转化规律。
