Air pollutant control and strategy in coal-fired power industry for promotion of China’s emission reduction

Weiliang WANG, Bo LI, Xuan YAO, Junfu LYU, Weidou NI

《能源前沿（英文）》 2019年 第13卷 第2期   页码 307-316 doi: 10.1007/s11708-019-0620-4

摘要： Coal-fired power industry has always been the major power source in China. As coal-fired power industry consumes around a half of China’s coal production, it is always thought to be a big air pollutant emission source. As more and more strict legislations in coal-fired power industry have been issued by the government, the emission performance in coal-fired power industry has been drastically reduced recently. Based on a brief review of the development of emission control in China’s coal-fired power industry, the affecting mechanism among the development of installed capacities of emission control device, pollutant emission, and emission performances in coal-fired power industry is studied. According to a systematic study on the development of emissions of classified categories, the role of coal-fired power industry as a pollutant source is reevaluated. It is found that, coal-fired power industry has contributed the most to China’s emission reduction, and the barycenter of air pollutant emission has been transformed to other high energy consumption industries, like heat, iron/steel, and cement. Then some development strategies are suggested, such as maintaining the current emission standard in coal-fired power industry; expending the coal-fired power emission standards to categories of heat generation and supply, nonmetallic mineral production and ferrous metals smelting and processing; and controlling other heavy metal by consulting the method of Hg control.

Numerical simulation of biodiesel fuel combustion and emission characteristics in a direct injection

Yi REN, Ehab ABU-RAMADAN, Xianguo LI,

《能源前沿（英文）》 2010年 第4卷 第2期   页码 252-261 doi: 10.1007/s11708-010-0036-7

摘要： The effect of the physical and chemical properties of biodiesel fuels on the combustion process and pollutants formation in Direct Injection (DI) engine are investigated numerically by using multi-dimensional Computational Fluid Dynamics (CFD) simulation. In the current study, methyl butanoate (MB) and -heptane are used as the surrogates for the biodiesel fuel and the conventional diesel fuel. Detailed kinetic chemical mechanisms for MB and -heptane are implemented to simulate the combustion process. It is shown that the differences in the chemical properties between the biodiesel fuel and the diesel fuel affect the whole combustion process more significantly than the differences in the physical properties. While the variations of both the chemical and the physical properties between the biodiesel and diesel fuel influence the soot formation at the equivalent level, the variations in the chemical properties play a crucial role in the NO emissions formation.

Temporal dimension and water quality control in an emission trading scheme based on water environmental

Zhaoxing HAN, Zhenyao SHEN, Yongwei GONG, Qian HONG

《环境科学与工程前沿（英文）》 2011年 第5卷 第1期   页码 119-129 doi: 10.1007/s11783-011-0272-z

摘要： Emission trading is one of the most effective alternatives to controlling water pollution. Water environmental functional zone (WEFZ) is used to determine the water quality standard and identify the zone boundary for each river or reach. In this study, a new emission trading scheme was addressed based on WEFZ, accounting for both the temporal dimension and water quality control. A temporal factor of emission trading was proposed based on variations in the environmental capacity within a year by dividing the year into three periods, including high, normal, and low periods of environmental capacity. During each period, emission trading was implemented exclusively. A water quality-control scheme was suggested based on the water quality requirement in the water functional zone, in which the water quality at the downstream boundary of the zone was required to meet the water standard following auto-purification in the stream. Two methods of calculating water quality control are addressed for point-source pollution and non-point-source pollution. The calculated temporal dimension and water quality control were located in Dongxi River of the Daning Watershed in the Three Gorges Watershed. The high period was during June, July, and August, the normal period was during April, May, September, and October, and the low period was during January, February, March, November, and December. The results from the water quality calculation demonstrated that the discharge of point-source and non-point-source pollutions led to an excess of common contaminants at the downstream boundary of WEFZ. The temporal and spatial factors above should be incorporated into the emission trading scheme based on WEFZ.

《工程（英文）》 2020年 第6卷 第12期   页码 1408-1422 doi: 10.1016/j.eng.2019.10.018

摘要：

我国能源以煤为主，发电是煤炭消费第一大户。针对煤电大气污染物排放带来的严峻生态环境问题，本文开展了清洁煤电近零排放技术研究与工程实践，评估了近零排放机组长周期运行状态，并探究了重金属汞协同和专门控制技术。结果表明，提出的近零排放技术路线煤质适应性强，应用到全国101台燃煤机组，大气污染物烟尘、SO2、NOx排放浓度低于燃气发电排放限值，长周期运行时排放浓度小时均值达标率超过99%，发电成本增加约0.01 元·(kW·h)–1。污染物总排放量降低约90%，有效改善了环境空气质量。近零排放机组汞排放浓度为0.51~2.89 μg·m–3，投运改性飞灰（MFA）专门脱汞系统，汞排放浓度可低至0.29 μg·m–3， 相同脱除效果下运行成本仅为国际主流活性炭脱汞的10%~15%。通过50 000 m3·h–1燃煤烟气中试平台研究，掌握了多污染物脱除过程中相互影响规律，形成了排放达到不同浓度限值的解决方案；结合示范应用，提出并实现了新的近零排放煤电“1123”生态环保排放限值，即烟尘、SO2、NOx和汞及其化合物排放浓度分别不高于1 mg·m–3、10 mg·m–3、20 mg·m–3和3 μg∙m–3，为“提高污染排放标准”提供了工程技术支撑。

Transient emission simulation and optimization of turbocharged diesel engine

Lingge SUI, Zhongchang LIU, Yongqiang HAN, Jing TIAN

《能源前沿（英文）》 2013年 第7卷 第2期   页码 237-244 doi: 10.1007/s11708-013-0251-0

摘要： In order to alleviate the pressure of experimental research of turbocharged diesel engine under transient operations, a whole process simulation platform for turbocharged diesel engine under transient operations was established based on the multi-software coupling technologies of Matlab/Simulink, GT-Power, STAR-CD and artificial neural network. Aimed at the contradiction of NO and soot emission control with exhaust gas recirculation (EGR) of turbocharged diesel engine under transient operations, on this simulation platform, a transient EGR valve control strategy was proposed, which adjusted the EGR valve in adjacent level based on the feedback of its opening according soot control limit under transient operations. Simulation and experimental results prove that the transient emission optimization effect of this control strategy is obvious. On the one hand, compared with the previous control strategy, which closed the EGR valve during the whole transient operations, soot emission is slightly increased by 9.5%, but it is still 9% lower than the control limit. On the other hand, compared with the previous control strategy, NO transient emission is reduced by 44%.

WATER POLLUTION AND AGRICULTURE: MULTI-POLLUTANT PERSPECTIVES

《农业科学与工程前沿（英文）》 2023年 第10卷 第4期   页码 639-647 doi: 10.15302/J-FASE-2023527

摘要：

Agriculture is an important cause of multiple pollutants in water. With population growth and increasing food demand, more nutrients, plastics, pesticides, pathogens and antibiotics are expected to enter water systems in the 21st century. As a result, water science has been shifting from single-pollutant to multi-pollutant perspectives for large-scale water quality assessments. This perspective paper summarizes and discusses four main highlights related to water pollution and agriculture from the multi-pollutant perspective. These highlights reveal the spatial and temporal distribution and main sources of multiple pollutants in waters. Based on the highlights, a scientific agenda is proposed to prioritize solutions for sustainable agriculture (UN Sustainable Development Goal 2) and clean water (UN Sustainable Development Goals 6 and 14). This agenda points out that when formulating solutions for water pollution, it is essential to take into account multiple pollutants and their interactions beyond biogeochemistry.
