| Abstract: |
| Based on the results of a field survey on scattered coal consumption for rural heating and the proportion of straw burned in open fields, this study assesses the feasibility of using densified solid fuels (DSFs) produced from field straw as an alternative for space heating purposes in rural areas of northern China. A quantitative analysis from the perspective of resource use was performed to evaluate the energy and environmental impacts of this alternative on reducing coal consumption as well as the emission of air pollutants. The results show that a majority of provinces in northern China may be able to realize a reduction in coal consumption and emissions by replacing coal with DSF produced from field straw for rural heating. Overall, this could yield a total reduction in coal consumption of 8.60×107 t. In addition, a total emissions reduction of 3.23×105, 2.75×105, 6.14×106, 6.33×105, 2.52×108 t may be accomplished for SO2, NOx, CO, PM2.5, and CO2, respectively. In particular, provinces such as Heilongjiang, Henan, Xinjiang, Shandong, Hebei, and Liaoning could achieve the most significant energy savings and emissions reductions. The potential energy and environmental impacts of coal-to-DSF substitution are demonstrated to be substantial. The application of DSF will help to address energy shortages, rural waste disposal, and air pollution. It is recommended that further research into the application of DSF in rural areas of northern China is needed. |
