摘　　要：在IGCC基础上发展起来的煤基甲醇动力多联产系统作为一种高效清洁的能源系统在中国具有广泛的应用前景。该文基于相对节能率,单位能量生产成本研究了联产系统热力性能和经济性能间的关联关系。研究表明,对甲醇动力多联产系统而言,不仅存在使相对节能率最高的最佳循环倍率,而且还存在使单位成本最低的最佳循环倍率。当化工岛的未反应气循环倍率位于2.17~4.44时,可以使相对节能率和单位成本二者都达到比较优化的状态。Coal-based methanol/power poly-generation system,which is based on IGCC,has been regarded as one of the promising technologies to use fossil fuel more efficiently and cleanly.The relevance of the thermodynamic and economic performances of this system was investigated.Relative energy saving rate(E_R) and unit energy production cost are respectively presented as a criterion to evaluate thermodynamic and economic performances.The study shows,for methanol/power poly-generation system,there is not only the best circulation ratio to make relative energy saving rate highest,but also there is the best circulation ratio making unit energy production cost lowest.The system was revealed that when the circulation ratio is between 2.17~4.44,both relative energy saving rate(E_R) and unit energy production cost could reach an optimal state.
