分别论述了太阳能预热与余热回收技术在我国印染行业中的应用现状，指出太阳能虽可无偿使用，但其投资大、回收期长，且由于供热温度较低，在印染行业中的使用受限；余热回收虽投资小、回收期短，但属于被动加热。故可将两种工艺结合起来，取各自优点联合使用。案例分析显示，太阳能预热与余热回收集热系统可以降低投资额，缩短回收周期。最后分析了该技术推广中存在的问题，提出了发展方向。

In this article, the application statuses of the solar energy preheating technology and waste heat re-covery technology in textile dyeing and finishing industry of our country are introduced. It points out that although solar energy can be used freely, solar energy preheating technology needs big investment and has long payback period, meanwhile, its usage is limited in dyeing and finishing industry due to its low heating temperature. The waste heat recovery technology has small investment and short payback period, however, it belongs to passive heat-ing system. Thus, these two kinds of technologies can be united applied in unison in order to take full use of their advantages. The results from case analysis show that for the new united technology, the investment cost decreases, the payback period is shortened. At last, the problems existing in the promotion of the new united technology are analyzed, with the develop direction given.
