摘要
为了提高生活垃圾焚烧碳排放计算的准确性,提出中国核证自愿减排量(CCER)方法学和平衡法结合的可能性.采用2种方法学分别计算5个不同地区的垃圾焚烧发电项目计入期内的碳排放,分析排放影响因素.结果表明,CCER方法学中的每吨垃圾基准线排放质量为0.26~0.40 t,项目排放质量为0.34~0.79 t,项目减排质量为-0.44~-0.05 t.平衡法仅对每吨垃圾项目排放质量进行计算,为0.24~0.50 t(不含生物源碳排放).对2种方法学项目排放量中的每吨垃圾焚烧产生的CO_(2)(化石源碳)排放量进行比较,利用CCER方法学计算得到的每吨垃圾排放质量为0.32~0.76 t;平衡法计算的范围为0.22~0.49 t,较接近文献值.垃圾样品的时空波动特性使得CCER方法学的计算结果具有较大误差;平衡法无须进行垃圾采样,是简便快捷、准确性高的碳排放实时在线计算方法学.平衡法可以替代CCER方法学中焚烧产生的CO_(2)(化石源碳)排放计算.
The possibility of combining Chinese certified emission reduction(CCER)method and balance method was proposed in order to improve the accuracy of carbon emission calculation for municipal solid waste(MSW)incineration.The two methods were used to calculate carbon emissions of five MSW incineration power generation projects in different regions during the crediting period,and the factors affecting carbon emissions were analyzed.Results showed that baseline emissions,project emissions and project emission reductions per ton waste were 0.26~0.40 t,0.34~0.79 t and-0.44~-0.05 t respectively in CCER method calculation.Only project emissions were calculated in balance method,ranging from 0.24 t to 0.50 t per ton waste(excluding biogenic source carbon emissions).The emission range of CCER method and balance method were 0.32~0.76 t and 0.22~0.49 t per ton waste respectively by comparing project emissions of CO_(2)(fossil source carbon emissions)from combustion of the two methods.The result of balance method was relatively close to the literature values.Results showed that a quite great error would happen in CCER method calculation due to the spatial and temporal fluctuations of MSW samples.Balance method was a convenient,fast and accurate method for real-time carbon emissions calculation,while MSW sampling was unnecessary during calculation.Balance method could replace the calculation of project emissions of CO_(2)(fossil source carbon emissions)from combustion in CCER method.
