Taking the practice of Chifeng's large temperature difference heating project as an example,this paper presents the design concept and implementation steps of low carbon heating scheme in Chifeng.From the shortage of heat sources,the estimation of the potential of steam waste heat,industrial waste heat and wind power conversion,the necessity of reducing the temperature of primary network return water,the promotion of large temperature difference heating and the implementation process in stages,and the heat balance at each stage in Chifeng are described in detail.According to the plan,by 2035,the heating heat in the central urban area of Chifeng comes from the conversion heat of wind curtailment power stored in non-heating season and industrial waste heat,as well as the heat of industrial waste heat and coal-fired peaking power plant in heating season.The carbon dioxide emission intensity per unit heating area is 1/30 of the current situation.
