有关部门初步计算的几项节能指标: 一、我国现有二十万台工业锅炉(不包括电厂的),每年耗煤二亿吨左右,平均运行效率百分之五十五。如提高效率百分之十,一年就可节煤二千万吨。 二、全国大中城市八千万居民,若采用气化法取暖作饭,比直接用煤作燃料,一年可节煤一千三百万吨。 Several energy-saving indicators have been initially calculated by the relevant departments: 1. China currently has 200,000 industrial boilers (excluding power plants), which consumes about 200 million tons of coal annually and has an average operating efficiency of 55%. If the efficiency is improved by 10%, 20 million tons of coal can be saved in one year. Second, 80 million inhabitants of large and medium-sized cities throughout the country can save 13 million tons of coal a year if they use the gasification method for heating and cooking instead of directly using coal as fuel.
