1.前言 日本1975年的能源消耗总量折算石油达到3900亿升。然而占消耗总量48％的能以废热形式被排放到大气、河川、海洋。 1976～1981年10月的六年间,废热利技术的研究、开发取得了显著进展。 2.开发研究的内容、技术重点及成果 2.1 热回收——热交换技术 1. Introduction Japan’s total energy consumption in 1975 converted the oil to 390 billion liters. However, 48% of the total consumption can be discharged to the atmosphere, rivers and oceans in the form of waste heat. During the six years from 1976 to October 1981, remarkable progress was made in the research and development of waste heat technology. 2. Development of research content, technology priorities and results 2.1 Heat recovery - heat exchange technology
