火力发电厂碳排放测量及分析

Measurement and Analysis of Carbon Emission in Thermal Power Plant

火力发电厂是中国二氧化碳主要排放源之一,实现火电厂碳减排对降低中国碳排放总量,减少温室气体排放具有重要意义。目前各火力发电厂碳排放量主要通过燃料量、煤炭含碳量、灰分等参数计算得到,影响因素较多,对某一区域碳排量具有指导意义,但无法准确得到单一火电厂碳排放量。本研究提出了一种火力发电厂二氧化碳烟气成分测量方法,并应用于某台660 MW超超临界机组。结果表明,采用带二氧化碳测量组分的烟气连续监测系统对火力发电厂进行碳排放监测,可精确的计算单台机组碳排放速率、碳排放总量,具有准确性、实时性的优点,可为碳排放权交易、低碳火电厂经济补偿等方面提供依据。

The thermal power plant is one of the main sources of carbon emissions in China. Carbon emission reduction of thermal power plants is of great significance to reduce China’s total carbon emissions and greenhouse gas emissions.At present, the carbon emission of the thermal power plant is mainly calculated by fuel quantity, carbon content, ash content and other parameters, this is affected by many factors. In this way, it has guiding significance for a certain area of carbon emissions, but can not accurately get the carbon emissions of a single thermal power plant. In this study, a measurement method of carbon dioxide flue gas composition was proposed and applied to a 660 MW ultra supercritical unit. The results show that this method can accurately calculate the carbon emission rate and total carbon emission of a single thermal power unit, and provide basic data for carbon emission trading and low carbon emission compensation.
