燃烧褐煤电厂中的沾污和结渣问题由于粘土的混入而进一步恶化,萨斯喀彻温动力公司已开始了一个旨在研究粘土和灰份的相互作用与电站锅炉中所观测到的结果相关关系的研究项目.除它们的化学特性之外,还测定了灰——粘土混合物的性能.包括熔融特性、粘度、同时导电性和膨胀性及抗压强度.结果表明获得的抗压强度数据与电厂的情况很吻合.高钙含量的褐煤灰允许有粘土夹杂物,但是,一旦钙混入到灰矿物质中,就将降低它们的防结渣和沾污性能。
The problem of fouling and slagging in burning lignite power plants is further exacerbated by the incorporation of clay and Saskatchewan has started a study to investigate the interaction of clay and ash with the results observed in utility boilers In addition to their chemical properties, the ash-clay mixtures were also tested for their properties including melt properties, viscosity, electrical conductivity and expansibility and compressive strength.The results show that the compressive strength obtained with Power plants are well matched: High calcium content of brown ash allows clay inclusions, but once calcium is incorporated into the ash minerals, it will reduce their anti-slagging and staining properties.
