燃煤电厂碳排放的核算方法对比分析

Comparative Analysis of Accounting Methods for Carbon Emissions from Coal-fired Power Plants

燃煤电厂固定排放源是我国CO_(2)的主要排放源,准确量化CO_(2)排放量是燃煤电厂实施碳资产管理、参与全国碳交易的基础。本文采用排放因子法和实测法,对江苏省某燃煤电厂固定排放源CO_(2)排放量进行对比分析。研究发现,实测法结果高于排放因子法,诸多因子均会影响核算结果。目前,火电企业已经普遍安装烟气排放连续监测系统(CEMS),具备增加CO_(2)监测功能的技术基础。CEMS通过改造可实现CO_(2)在线监测,因此开展CO_(2)在线监测具有较高可行性。

The fixed emission source of coal-fired power plants is the main source of C02 emissions in China,accurately quantifying C02 emissions is the foundation for coal-fired power plants to implement carbon asset management and participate in national carbon trading.This paper uses the emission factor method and the actual measurement method to compare and analyze the CO_(2) emissions from the fixed emission source o£a coal-fired power plant in Jiangsu Province.Research has found that the results of actual measurement method are higher than the emission factor method,and many factors can affect the accounting results.At present,thermal power enterprises have generally installed continuous emission monitoring system(CEMS),which have the technical foundation to add CO_(2) monitoring functions.CEMS can achieve online monitoring of CO_(2) through transformation,so it is highly feasible to carry out online monitoring of CO_(2).
