基于低碳排放的发电模型研究 -

整体煤气化联合循环(IGCC)发电技术具有发电效率高、污染物排放低、节水性能先进、有利于实现CO2减排等特点,是国际上公认的洁净、高效的发电技术之一。建立了基于低碳排放的IGCC发电模型,并分别对IGCC发电系统的两部分(煤气化系统和燃气-蒸汽轮机联合循环发电系统)建立了评价子模型。通过模型,计算不同煤质的IGCC系统能效、供电标煤耗及单位电量CO2排放量,并将模型计算结果与国内电厂的煤气化粗煤气组成、国际上大型联合循环机组的热效率进行了对比,验证了模型的合理性和准确性。 IGCC has many great advantages such as high power generation efficiency,low pollutant and CO2 emissions,perfect water-saving performance and the like.It's one of the cleanest and highest efficiency power generation system.Estabilish IGCC model based on low-carbon emissions,also develop the evaluation sub-model of IGCC-coal gasification system and gas-steam turbine combined cycle power generation system.Calculate the IGCC system efficiency,power supply standard coal consumption and unit power CO2 emissions of different coal qualities with these models.Compare the raw gas composition and thermal efficiency calculated by the model with those of practical power plants at home and international large-scale combined cycle units.The results show that the calculation results of model is accurate and reliable
