Research and challenges of clean and low-carbon heating system under the'dual carbon'goal
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.
