一九七五年日本曾对全国耗能量及其结构作过分析。结果发现在能源消耗中约有50%作为废热被排放到大气、河流和海洋中去。因此,若对钢铁、电力、化工等主要耗能部门从所排放废热中回收并利用余热,其节能及经济效果必将显著而且有益。本文主要是概述利用化学法进行余热输送、热贮存的技术和装置,及其应用。一、热输送和热贮技术基本特点要对余热有效地加以回收利用,必须考虑热的输送和贮存。热的长距离输送一般都不稳定,要使成
In 1975, Japan made an analysis of the national energy consumption and its structure. As a result, about 50% of energy consumption is discharged into the atmosphere, rivers and oceans as waste heat. Therefore, if the major energy-consuming sectors such as steel, electricity and chemical industry recover and utilize waste heat from the waste heat discharged, the energy-saving and economic effects will certainly be significant and beneficial. This article is an overview of the use of chemical waste heat transport, heat storage technology and equipment, and its application. First, the basic characteristics of heat transfer and heat storage technology To effectively waste heat to be recycled, you must consider the heat transport and storage. Hot long distance transport are generally unstable, to make into
