[摘 要]燃煤发电作为我国当前主导能源,其 CO2排放在全社会占比举足轻重。为实现碳达峰、碳
中和目标,迫切需要掌握现有燃煤发电机组碳排放强度影响因素,以不断降低碳排放强度。

量机组 CO2排放强度相对较低,直接空冷机组 CO2排放强度相对较高;随着机组负荷下降,
CO2排放强度呈现增大趋势;燃煤单位热值含碳量、碳氧化率、硫分、挥发分等均会影响
CO2排放强度,排烟方式、环境温度等的影响可以忽略不计。本文研究结果可以为工程设

Abstract: As the chief energy in China, the carbon dioxide(CO2)emission of coal-fired power generation has
accounted for an important proportion in the whole society. In order to achieve the carbon peak and carbon
neutralization goals, reduce the CO2 emission of coal-fired power generation. It has become urgent to master the
influencing factors of carbon emission intensity of existing coal-fired generating units. In this paper, typical
coal-fired generating units were selected in large coal-fired power bases such as Northern Shaanxi, Ningdong,
Zhundong and Hami.The relationship was studied between CO2 emission intensity and unit type, operating load,
coal quality, air cooling mode and other factors. The results show that, the CO2 emission intensity of high
parameter and large capacity units is relatively low, and the CO2 emission intensity of direct air cooling units is
relatively high. As the unit load decreases, the CO2 emission intensity increases. The carbon content per unit
calorific value, carbon oxidation rate, sulfur content and volatile matter of coal will affect the CO2 emission
intensity. The effects of smoke exhausting mode and ambient temperature can be ignored. The research results can
provide a guidance for engineers to design or reconstruct the green and low-carbon power plants, a path for power
generation groups to strengthen carbon emission management and reduce carbon emission intensity, and a
reference for power dispatching departments to optimize the load arrangement.
