摘要
梳理了当前全国和上海的碳排放配额方案中关于燃气分布式供能项目的核算方法,通过一个能源中心的算例来展现核算过程,分析了全国和上海方案的特点和适用性.提出了基准效率的概念,即足额获得碳排放配额时机组的热效率基准,并基于上海配额方案推算了供热机组配额指标蕴含的基准效率,得出燃气锅炉供热的基准效率为90%,燃气分布式供能机组基准效率为82%,并基于基准效率的机组,按供应1万t蒸汽进行测算,燃气分布式供能项目较燃气锅炉具有60%的减排效果.提出了进一步完善配额分配机制的建议,通过设置统一的供热排放系数、调整供电折算方法,建立配额引导激励机制,倡导使用碳排放核算工具指导能源项目建设和运行实践,推进高排放机组逐步转向使用低排放设备.
Abstract
This paper summarizes the accounting methods for gas distributed energy supply projects in the current carbon emission quota schemes in China and Shanghai.The accounting process is demon-strated through an example of an energy center,and the characteristics and applicability of the national and Shanghai schemes are analyzed.The concept of benchmark efficiency was proposed,which refers to the thermal efficiency benchmark of units when obtaining carbon emission quotas in full.Based on the Shanghai quota scheme,the benchmark efficiency contained in the quota indicators of heating units was calculated.The benchmark efficiency of gas boiler heating was 90%,and the benchmark effi-ciency of gas distributed energy supply units was 82%.Based on the benchmark efficiency of units,cal-culated by supplying 10000 tons of steam,gas distributed energy supply projects have a 60%emission reduction effect compared to gas boilers.Suggestions have been put forward to further improve the quota allocation mechanism,by setting a unified heating emission coefficient,adjusting the power sup-ply conversion method,establishing a quota guidance incentive mechanism,advocating the use of car-bon emission accounting tools to guide energy project construction and operation practice,and promot-ing the gradual shift of high emission units to use low emission equipment.
