Abstract

Northern cities in China have frequently suffered from ice and snow disasters. On the other hand, Harbin mainly relies on coal-fired plants for heating during the winter time. However, coal-fired plants produce a significant amount of air pollution through the production of numerous hazardous gases. This thesis proposed an urban energy recycling system that uses waste gas from heating facilities to recycle waste heat and reduce air pollution in northern cities during the winter. This research made a hypothesis that wintertime ice and snow on city streets could be melted by using waste heat of waste gases from heating industries. The methodology of this research can be divided into three parts: Firstly, the principle of theenergy recycling system is designed based on investigation. Secondly, a simulation experiment is used to analyze the system's difficulties. According to the experiment, when anicy road is far away from the heating industry, ice melting efficiency is low. Finally, this research proposed a method for system improvement based on the findings of the experiment. The system's environmental and social benefits will likely lead to its future application in northern Chinese cities even if there are many application-related difficulties, such as the high cost of construction.
