本文对一种新型余热回收换热器进行了理论及实验研究.提出其蒸发室结构设计的基本数据,并且对其冷凝器中采用流化床技术米提高传热系数的方法进行了探讨,对换热器的传热规律进行了研究.结果表明:这种换热器与壳管式水-水换热器相比,传热系数提高一倍左右,能有效地减少传热面积. In this paper, a new type of waste heat recovery heat exchanger was studied theoretically and experimentally, the basic data of the design of the evaporation chamber was proposed, and the method of increasing the heat transfer coefficient by using the fluidized bed technology in the condenser was discussed. The heat transfer law of the heat exchanger was studied.The results show that the heat transfer coefficient is doubled compared with the shell-and-tube water-water heat exchanger, which can effectively reduce the heat transfer area.
