Experiments were conducted in a thermogravimetric analyzer to assess the enhancement of combustion characteristics of different solid fuels blended with organic calcium compounds (OCCs). Rice husk, sewage sludge, and bituminous coal, and two OCC were used in this study. Effect of different mole ratios of calcium to sulfur (Ca/S ratio) on the combustion characteristics were also investigated. Results indicated that combustion performance indexes for bituminous coal impregnated by OCC were improved, however, an inverse trend was found for sewage sludge because sewage sludge has lower ignition temperature and higher volatile matter content compared to those of OCC. For rice husk, effect of added OCC on the combustion characteristics is not obvious. Different solid fuels show different combustion characteristics with increases of Ca/S ratio. The maximum combustion performance indexes appear at Ca/S ratios of 1:1, 2:1, and 3:1 for OCC blended with Shenhua coal, rice husk, and sewage sludge, respectively.
实验在热重分析仪中进行，以评估不同固体燃料与有机钙化合物（OCC）混合后的燃烧特性增强情况。本研究使用了稻壳、污水污泥和烟煤，以及两种 OCC。还研究了不同钙硫摩尔比（Ca/S 比）对燃烧特性的影响。结果表明，用 OCC 浸渍的烟煤的燃烧性能指标得到了提高，而对于污水污泥则出现了相反的趋势，因为与 OCC 相比，污水污泥的点火温度更低，挥发分含量更高。对于稻壳，添加 OCC 对燃烧特性的影响并不明显。不同的固体燃料随着 Ca/S 比的增加呈现出不同的燃烧特性。对于与神华煤、稻壳和污水污泥混合的 OCC，最大燃烧性能指标分别出现在 Ca/S 比为 1:1、2:1 和 3:1 时。
