石灰石固硫特性指标体系的建立与综合评价

Contruction and Evaluation of Desulfuration characteristics of Limestone

采集18个产地的石灰石样品，对其进行了固硫特性三项指标A、K、C的测定，分别按着各项活动指标的大小，把石灰石固硫特性的优劣分为四级，建立了石灰石主要化学成分与各项活动指标的预测模型；利用主要成分分析对各项活动指标赋权，通过与理想点的贴近度给出各样品关于三项活动指标的综合得分，从而对石灰石固硫特性的优劣进行综合评价，以便应用于锅炉烟气脱硫系统。

Three indexes A, K and C of desulfurationcharacteristics were determined for limestone samples from18 sources, and according to the magnitudes of differentactivities, the desulfuration characteriestics of limestoneswere classified into 4 grades and models were built forprediction of major compositions of limestone and indexesof different activities. Through major composition analysisand assignment of activity indexes, overall marks weregiven to A, K and G of different samples in accordancewith their closeness to the idea point, and an overall eval-uation was thus made of the desulfuration characteristies oflimestones so that they can be used in the gas desuifura-tion systems of boilers as appropriate.
