摘要

针对现有燃煤电厂中各单元碳排放责任分摊不明确、系统评价方法不完善的问题，提出了一种新的能量系统分析方法，以定量揭示机组内部的碳排放责任，分析不同工况下机组的碳排放水平。以典型1000 MW燃煤发电机组为研究对象，建立了能量系统单元碳效与关键参数的相互作用模型。将碳效作为指标，分析了碳效与关键参数之间的关系，进而评价了各工况下机组的碳排放水平及相关因素的影响。结果表明，将碳效处于0.95~1.00作为高碳效区间，关注整体碳效则需要将机组工况维持在85.2%以上；关注锅炉和汽轮机单元各自的碳效，则需要将锅炉给水量和汽轮机主蒸汽流量分别控制在2769.02~3005.16 t/h和1484.45~2975.11 t/h。

Abstract

To address the issues of ambiguous carbon emission responsibility allocation among units and incomplete system evaluation methods in existing coal-fired power plants

a novel energy system analysis method was proposed to quantitatively reveal the internal carbon emission responsibilities and analyze the carbon emission levels of the units under various operating conditions. Taking a typical 1000 MW coal-fired power plant as the research object

an interaction model between the carbon efficiency of energy system units and key parameters was established. Using carbon efficiency as the objective function

the relationship between carbon efficiency and key parameters was analyzed

and the unit’s carbon emission levels and the influence of related factors under different operating conditions were evaluated. The results show that when taking the carbon efficiency of 0.95 to 1.00 as the high carbon efficiency range

to focus on the overall carbon efficiency

the unit operation condition needs to be maintained above 85.2%

and to focus on the carbon efficiency of the boiler and the steam turbine unit

the boiler feed water volume and the main steam flow of the steam turbine need to be controlled within the ranges of 2769.02 t/h to 3005.16 t/h and 1484.45 t/h to 2975.11 t/h

respectively.
