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

Frontiers in Energy 2019, Volume 13, Issue 2, Pages 307-316 doi: 10.1007/s11708-019-0620-4

Abstract: 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.

Emergy evaluation of polygeneration systems

WANG Lingmei, LI Zheng, NI Weidou

Frontiers in Energy 2007, Volume 1, Issue 2, Pages 223-227 doi: 10.1007/s00000-007-0030-x

Abstract: To expand the application range of the emergy evaluation method, an emergy evaluation index, which can reflect the particular feature of polygeneration systems, has been elaborated on the basis of energy and emergy conservation, guided by the fundamental principle of emergy analysis. With this index, the cost structure, emission effect and energy saved were all considered on the same level of importance. To exemplify, some power polygeneration systems (methanol-power generation, hydrogen-power generation) are considered using coal as the basic fuel. The results showed that emergy evaluation indices are practical for comprehensively evaluating polygeneration systems and their sustainability, which is influenced by such factors as the joining mode of polygeneration and the technologies used. The sustainability of polygeneration systems, which work on an appropriate ratio of fuel-to-electric power basis, is higher than that of singular production systems.
