北部盆地和巴-德-加莱的经验法国北部盆地和巴-德-加莱煤矿诸电厂(H.B.N.P.C)的锅炉,设计燃料是洗过的下脚煤(混煤,粉状煤,煤屑和泥煤)。这些下脚煤的灰分变化范围为25～50％。若干年来,甚至老废矿采得灰分达70％的下脚煤也供电厂使用。本文是对各电厂燃烧多灰分煤的经验作一简要介绍。 Experience in the Northern Basin and Barde-Calais Boilers in Northern France and the Barn de Gale coal-fired power plants (HBNPC) are designed to be washed with lower coal (mixed coal, pulverized coal, coal chips and mud coal). The ash content of these lower coal varies from 25% to 50%. For several years, even the old waste ore 70% of the ash obtained by ash extraction is also used by power plants. This article is a brief introduction of the experience of burning multiple ash coal in power plants.
