目前工业废气热量回收的设备有两大类:可流式换热器和再生式换热器。随着工业余热回收技术的发展,再生式换热器不断改进。热轮就是近来研制的一种受热而运动的再生式换热器。美国工业余热回收学会将热轮与其他气体余热回收设备进行了比较,见表1。 At present, there are two types of equipment for heat recovery of industrial exhaust gas: flowable heat exchangers and regenerative heat exchangers. With the development of industrial waste heat recovery technology, regenerative heat exchangers continue to improve. The heat wheel is a recently developed regenerative heat exchanger that is heated and moved. The American Society for Industrial Waste Heat Recovery compares the hot wheels with other gas waste heat recovery equipment, as shown in Table 1.
