一、前言由于石油危机的日益加剧以及原子能发电的停滞不前,给能源供应造成了一定的困难,面临着这种情况,埋藏虽比较丰富的煤重新引起人们的重视。在日本包括电源开发公司在内的各个电力公司也开始进行专烧煤的火力发电站的建设和研究工作。而且有些公司已经开始从专烧重油转向烧煤,并开始从澳大利亚进口煤。与此同时有许多水泥公司也转向使用煤作燃料。 I. INTRODUCTION Due to the worsening oil crisis and the stagnating nuclear power generation, the supply of energy has caused some difficulties. In the face of this situation, the burial of rich coal re-attracted people’s attention. Various power companies in Japan, including power development companies, have also begun construction and research work on coal-fired thermal power plants. And some companies have started shifting from burning heavy oil to coal and starting to import coal from Australia. In the meantime, many cement companies are also turning to using coal for fuel.
