This article describes the thermal media waste heat recovery technology for the recovery of industrial waste gas from 250 ~ 450 ℃ and the use of waste heat. This article focuses on the basic composition of the technology and its application in hot stove abroad. 1. Heat Medium Waste Heat Recovery Device and Its Development 1.1 Schematic The basic components of heat medium heat recovery device are shown in Figure 1. Heat exchangers 1 and 2 are connected by suitable pipes, and a pump is connected in series in the pipeline. The heat medium forcedly circulated by the pump in the closed circuit is sucked from the heat source through the heat exchanger 1
