摘　　要：在保证燃煤锅炉机组正常运行,满足所需机组负荷的情况下,为提高配煤的成本、热值、硫分、灰分和挥发分等综合指标,采用混料试验设计方法以高热低硫煤、中热中硫煤以及低热高硫煤为三因素进行极端顶点法配煤设计。通过对试验数据进行分析处理,建立了多指标响应优化模型并结合企业配煤现状和环保要求,求得三因素最佳比例。研究结果表明,当高热低硫煤、中热中硫煤和低热高硫煤的加入比例为4:3:3时,综合指标达到最优。Under the preconditions of ensuring the normal operation of coal-fired boiler unit and meeting the needs of the unit load,in order to improve the composite indicators such as coal distribution cost,calorific value,sulfur content,ash content,volatiles and so on,on the principle of mixture test design,with consideration of three factors including high-calorie & low-sulfur coal,medium-calorie & medium-sulfur coal and low-calorie & high-sulfur coal,the extreme vertex method was adopted for coal distribution design. In combination with the enterprise coal distribution status and environmental protection requirements,the optimal proportion of three factors was obtained by using the multi-index response optimization model which established by analyzing and processing the test data. The results in-dicate that the optimal composite indicators can be achieved when the proportion of high-calorie & low-sulfur coal,medium-calorie & medium-sulfur coal and low-calorie & high-sulfur coal is 4 ∶ 3 ∶ 3.
