近年来,能源的合理和充分利用已成为世界上最迫切的一个问题。党的十二大提出的宏伟载斗目标中也提出了要大力节约能源,其中包括充分利用低位能。余热资源常分为三类:高位能、普通能和低位能,属于前一、二类的就是各种锅炉、工业炉和其他各种炉窑的排烟余热。这些余热已经用余热锅炉、省煤器,换热器得到了较好的利用,但这两类余热的利用率还不充分。现在的余热锅炉和省煤器还不可能
In recent years, the rational and full use of energy has become one of the most pressing issues in the world. The ambitious goal put forward by the party’s 12th National Congress also put forward the need to vigorously save energy, including making full use of low-level energy. Waste heat resources are often divided into three categories: high energy, general energy, and low energy. The first and second categories are the exhaust heat from various boilers, industrial furnaces, and other furnaces. The waste heat has been used in waste heat boilers, economizers and heat exchangers. However, the utilization of these two types of waste heat is still insufficient. Now it is impossible for waste heat boilers and economizers
