Gas-Solid Heat Transfer in Waste Heat Recovery Device with Different Pipeline Arrangements EM Tang, J Ding, JF Lu

Abstract

In this paper, gas-solid heat transfer in waste heat recovery device with different pipeline arrangements is studied. The pipeline can enhance heat transfer in waste heat recovery device, and the system with pipeline has higher outlet gas temperature. Compared with paralleled arrangement, temperature distribution of staggered arrangement is more uniform and heat transfer is better. It addition, the decrease of inlet velocity and particle diameter can improve the outlet gas temperature.
