Research on the potential of low temperature waste-heat heating resources based on multi-factor constraints

Low temperature waste-heat heating is an important technology for clean heating.But the resource potential of low temperature waste-heat used for heating will be affected by time, space, temperature, industrial development and other factors.Therefore, the resource potential of low temperature waste-heat for long-term, effective & stable heating should be studied.In this study, the resource potential of low temperature waste-heat for heating was studied by the scenario analysis method and the results show that, the low temperature waste-heat resources available for heating in the northern region are about 62.262 million tce, and the heating area is about 8.12 billion square meters in 2017.Among them, the low temperature waste-heat resources above 80℃ account for 25.2%.In the future, the low temperature waste-heat resources available for heating will be 68.98 million tce, and the heating area is about 12.14 billion square meters in 2020.The low temperature waste-heat resources available for heating will be 66.487 million tce, and the heating area is about 11.7 billion square meters in 2030.
