摘要
从低碳区域供热、低品位余热利用及低能耗建筑等3个方面,分析"双碳"目标下清洁低碳供热系统的研究与挑战,给出清洁低碳供热技术在实施前后取得的节能效果.结果表明,通过回收现有火电厂的余热和大型钢铁厂的工业废热可以有效扩大低碳区域供暖系统,但该方法仅适用大型余热源、高加热密度及存在大型供热网络的城市.低品位余热的利用可以使用热泵、梯级加热及蓄热等技术,促进供热系统的清洁低碳运行.低能耗建筑能有效耦合了各种节能技术,可以降低建筑能耗水平.
Abstract
This paper analyzes the research and challenges of clean and low-carbon heating systems under the'dual carbon'goal in three aspects:Low-carbon district heating,low-grade waste heat utilization and low-energy buildings,and reveals the effects of clean and low-carbon heating technologies before and after implementation.The results show that the low-carbon district heating system can be effectively expanded by recovering the waste heat of existing thermal power plants and the industrial waste heat of large steel plants,but this method is only suitable for cities with large waste heat sources,high heating density and large heating networks.The utilization of low-grade waste heat can use heat pumps,cascade heating and heat storage technologies to promote the clean and low-carbon operation of the heating system.Low-energy buildings can effectively couple various energy-saving technologies to reduce the level of building energy consumption.
