摘　　要：基于钢渣辊压破碎—有压热闷处理工艺,采用汽水相变储热和防腐换热技术,开发一套钢渣热闷区余热回收装备,形成“热闷蒸汽—相变储热—热网采暖(余热发电)”的技术路线。该技术实现了非连续含尘蒸汽的回收和热源稳定输出,并在济源钢铁公司建成钢渣热闷余热供暖示范工程。经过一个供暖季的试运行,采暖供回水温度完全可以满足冬季采暖和厂区洗浴的需求,为钢铁低碳发展提供了技术支撑。Based on the process of steel slag roll crushing and pressure heat tightness treatment, a set of waste heat recovery equipment for steel slag heat tightness area is developed by using phase change heat storage and anticorrosive heat exchange technology, forming the technical route of “heat tightness steam-phase change heat storage-heat network heating(waste heat power generation)”.The technology has realized the recovery of discontinuous dust-bearing steam and the stable output of heat source, and built a demonstration project of steel slag heat dissipation and waste heat heating in Jisteel.After a trial operation in the heating season, the temperature of heating supply and return water fully meets the needs of winter heating and bath in the factory area, and provides technical support for the low-carbon development of steel.
