目前,许多工厂余热的利用率,特别是低温余热的利用率还很低。其中一个原因是囿于本厂范围内,往往难以给某些余热找到合适的用途,或者回收利用很不经济。针对上述情况,在本厂充分回收利用余热的基础上,打破厂界,相邻工厂之间采用回收余热联合系统,扩大余热的可用范围,可进一步提高余热利用率。因为工厂的性质不同,产品及数量不同,热源和温位也往往不同,这
At present, the utilization of waste heat in many factories, especially the utilization of low temperature waste heat is still very low. One of the reasons is that it is within the scope of the factory and it is often difficult to find a suitable use for some waste heat, or it is not economical to recycle. In view of the above situation, on the basis of full recovery and utilization of waste heat in the factory, we will break the boundary of the plant and use a system for recovering waste heat between neighboring plants to expand the available range of waste heat and further increase the utilization rate of waste heat. Because of the different nature of factories, products and quantities, heat sources and temperature levels are often different.
