摘要
针对某电厂实际的煤炭供应情况,挑选了常用的6种典型煤质,对该电厂7号和8号机组进行了330 MW负荷试验,得到了煤质对于锅炉效率影响的数据,并对煤炭基准价对发电成本的影响进行了计算分析,得出了合理的燃煤采购指导价格,以使机组的运行成本得到了保证。
Based on actual conditions of coal supply in a certain power plant, 6 typical kinds of coal were used to carry out loading experiments for its unit No. 7 and 8, hence the influencing data of coal quality on boiler efficiency obtained. By analyzing the influence of basic coal price on power generating cost, a guiding price is proposed for coal procurement so as to keep an acceptable operational cost of the unit.
