  ABSTRACT: Steel industry is high energy-consuming industry, and its wasteheat recovery is criticallyimportant for energy utilization. In this study, pipeline bundle is used to enhance heat transfer inwasteheat recovery device,andassociated gas-solid heat transfer and energy utilization performance with different pipeline arrangement, pipe diameter and shape of internal component are further analyzed. The temperatures of gas and particle in device with pipeline bundle periodically fluctuate in horizontal direction, and those in staggered system distribute more uniformly than those in paralleled system. Compared with paralleled device, exergy and waste heat utilization efficiency of staggered device have been improved, and they are both higher thanthose without pipeline. As pipe diameter increases, exergy and waste heat utilization efficiency first increases and then decreases, and they reach the maxima with optimal pipe diameter.As the width of internal component keeps constant, influence of its shape on heat transfer is very little.
