摘要
研究碳减排的前提之一即需要计算碳排放量,目前国际上普遍使用IPCC给出的碳排放计量方法进行计算。但对于燃煤火电行业,IPCC方法过于简化,导致碳氧化因子偏离实际值。本文以某300MW亚临界燃煤火电机组为例,研究燃煤火电机组碳氧化因子受机组负荷、煤质等因素的影响规律,通过将煤质的工业分析简化为煤质因子,揭示了碳氧化因子与煤质的关联关系。此外,本文利用工程数据计算了该机组年度CO_2排放量,指出了与IPCC默认计算结果的差异所在。
Carbon emission estimation is one of the preconditions to research carbon emission reduction.The carbon emission estimation method proposed by IPCC is the most commonly used in the world at present.However,the over simplification of carbon oxidation factor used in the IPCC method lead to a deviation from actual values.Based on a 300MW subcritical thermal power generating unit,the influences of unit load and coal quality on carbon oxidation factor were studied in this paper.A normalized factor（F_z） was used to qualify the coal quality.In addition,the CO_2 emission of this unit was calculated by using engineering data,and the discrepancy of IPCC default was presented.
