Abstract: Lowtemperaturewaste-heatheatingisanimportanttechnologyforcleanheating.Buttheresourcepotentialoflowtemperaturewaste-heatusedforheatingwillbeaffectedbytime,space,temperature,industrial development and other factors.Therefore,the resource potential of low temperature waste-heatforlong-term,effective&stableheatingshouldbestudied.Inthisstudy,theresourcepotentialoflowtemperaturewaste-heatforheatingwasstudiedbythescenarioanalysismethodandtheresultsshowthat,thelowtemperaturewaste-heatresourcesavailableforheatinginthenorthernregionare about62.262milliontce,andtheheatingareaisabout8.12 billionsquare metersin2017.Among them,thelowtemperaturewaste-heatresourcesabove80℃ accountfor25.2%.Inthefuture,thelow temperaturewaste-heatresourcesavailableforheatingwillbe68.98milliontce,andtheheatingareais about12.14billionsquaremetersin2020.Thelowtemperaturewaste-heatresourcesavailableforheat
