| 摘 要： | 换热网络是能量回收利用系统中的一个重要系统。对换热网络结构已定或已在运行的换热网络,如何优化改进使其达到最优,或在换热网络中的物流的流量、进出口温度发生变化时,要求换热网络的换热仍能满足工艺上的要求,要解决这一问题,通过采用夹点技术对某厂1.0Mt/a常压换热网络进行的分析,确定了最优夹点温差,为节能优化提供依据。

| Abstract: | Heat Exchanger Network （HEN） is an important subsystem of energy recovery process. The retrofit of heat exchanger network is how to improve a heat exchanger network with a certain structure or operated and make it to be optimal while the flows and the inlet and outlet temperatures of the streams are changed and the heat exchanger network can also meet the technological demand and operation under the optimum condition or close to optimum. In the paper, we analyze the heat recovery system to find the optimal temperature difference of pinch, and to provide the basis for Energy Conservation. |
