Energy Transfer Diagrams and Efficiency Analysis of Coal Industry Chain in Jing-Jin-Ji Region

摘要

Nowadays, the air pollution of China is more and more serious, especially in Jing-Jin-Ji region. The improper energy consumption structure and the pollutants emission of coal industry chain are the main cause of the air pollution. In this study, based on the Energy Balance Tables of Beijing, Tianjin and Hebei in 2012, we used the model of inter-regional transportation, proposed a Regional Coal Industry Chain Balance Table, clarified the material/energy flows, and accounted the energy utilization efficiency in Jing-Jin-Ji region. It can help to realize the optimal balance of pollutant emissions control and energy supply, which is scientifically innovative.
