煤,作为产生能源的一种燃料,预计在21世纪中仍扮演日趋重要的角色。然而,考虑到对世界环境的影响,极有可能在21世纪末将限制煤的使用。因此,本文的论点是:不管这种可能性是否成立,笔者认为目前正积极进行的改进煤的燃烧及其能量转换过程和改善燃烧煤对环境影响的研究一定会继续下去,且这些研究的结果将有益于全世界。作为一种能源,图1为煤与其它化石燃料的储量比较,表示了世界现有储量和新增加的预测储量。以上述数据为基础,预测世界燃 Coal, a fuel that generates energy, is expected to play an increasingly important role in the 21st century. However, given the impact on the world environment, it is highly probable that the use of coal will be limited by the end of the 21st century. Therefore, the argument of this article is: Regardless of whether this possibility holds or not, the author believes that the ongoing research to improve coal combustion and its energy conversion process and to improve the environmental impact of coal combustion will continue, and the results of these studies It will be good for the world. As an energy source, Figure 1 shows a comparison of reserves of coal with other fossil fuels, showing the world’s existing stocks and the newly added projected reserves. Based on the above data, predict the world burning
