一、研制陶瓷换热器的必要性需要经过高温过程的钢铁、玻璃、陶瓷等工业一直是耗能大户。在任何直接加热的工业过程中,能量损失均在30至90%之间,且这些过程的操作温度愈高,烟气所损失的能量就愈多。例如,当操作温度为871℃(1600°F)时,捆气损失的能量约为输入的45%;当温度提高到1319℃(2400°F)时,烟气损失便提高到约65%(如图1所示)。而事实上,上述耗能大户的焙烧过程有相当一部分是在较高温度下进行(如在美国工业中,燃气温度在871℃(1600°F)以上的工业过程约占40%)。
First, the necessity of developing ceramic heat exchangers Steel, glass, ceramics and other industries that require high temperature processes have been energy-hungry. In any directly heated industrial process, energy losses are between 30 and 90%, and the higher the operating temperature of these processes, the more energy is lost to the flue gas. For example, when the operating temperature is 871 ° C (1600 ° F), the energy loss of the bundling is about 45% of the input; when the temperature is increased to 1319 ° C (2400 ° F), the flue gas losses increase to about 65% As shown in Figure 1). In fact, a significant portion of the above-described roasting processes by energy-hungry customers are performed at higher temperatures (as in the U.S. industry, industrial processes with gas temperatures above 871 ° C (1600 ° F) account for about 40%).
