摘要
为研究燃煤机组碳排放特性,在深入分析GB/T 32151.1—2015中计算碳排放量方法学的基础上,建立了供电碳排放强度简化计算模型和详细计算模型,并通过实测单位热值含碳量和碳氧化率数据对所建模型进行了可靠性验证,证明了所建模型能相对准确快速地获得机组碳排放强度。以某电厂超高压循环流化床机组为例,基于所建模型深入分析了供电煤耗和煤种对碳排放相关指标影响,结果表明供电煤耗和煤种标煤的碳排放系数的减小可显著降低机组碳排放强度,并给出了发电企业控制碳排放的相关建议,为发电企业碳排放管理工作提供了参考。
To analyze the carbon emissions characteristics of coal-fired power plant accurately,a simplified calculation model and a detailed calculation model of power supply carbon emission intensity are established based on the China national standard GB/T32151.1,and the reliability of the established models is verified using the measured carbon content of unit calorific value and carbon oxidation rate data,which shows that the proposed model can accurately and quickly obtain the carbon emission intensity of the power plant.Taking an ultra-high pressure CFB(circulating fluidized bed)unit as an example,the influences of net coal consumption and coal type characteristics on carbon emissions are analyzed according to the detailed calculation model,which shows that the decrease of net coal consumption and carbon emission coefficient of standard coal can reduce the carbon emission intensity,then some suggestions on carbon emission management are given,which provides a reference for the management of carbon emissions in the other power plants.
