【摘要】 以赤峰市大温差供热工程实践为例，介绍了赤峰市低碳供热方案的设计理念和实施步骤。从赤峰市供热热源紧缺，城区周边电厂乏汽余热、工业余热和弃风电力转化热量潜力估算，降低一次网回水温度必要性，大温差供热推进和分阶段实施过程，各阶段热平衡等5个方面进行了详细说明。根据规划，至2035年赤峰市中心城区供热热量来源于非供暖季储存弃风电力转化热量和工业余热，以及供暖季工业余热和燃煤调峰电厂热量，单位供热面积的二氧化碳排放强度是现状的1/30。更多还原

【Abstract】 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.更多还原
