Abstract: Under the background of the national goal of carbon peak and carbon neutralization, the energy saving and economic analysis of the third generation integrated heat tracing station are carried out. The results show that compared with the traditional carbon steel tracing pipeline, the total length of the tracing pipeline is calculated as 20 kilometers, the third generation integrated heat tracing station is adopted, which reduces the radiation and convection heat loss by 62.57% and 11,988.8 tons of steam loss per year, equivalent to 3,245 tons of CO₂ emission; the modular purchase cost of the third generation integrated heat tracing station is 52.67% of the price of bulk material purchase plus installation cost, which has significant economic advantages; the modular procurement method of the third generation integrated heat tracing station has a delivery time of only 30 days, which greatly shortens the project construction period and has a significant time advantage. The promotion of the third generation integrated heat tracing station and modular procurement will help to save energy, reduce CO₂ emissions, reduce procurement costs and shorten the construction period.

摘要： 在国家提出了碳达峰、碳中和目标的背景下,对第三代集成伴热站进行了节能及经济分析,结果表明:①相比传统碳钢伴热管道,采用第三代集成伴热站,伴热管总长以20 km计算,散热损失减少了62.57%,每年减少11 988.8 t的蒸汽损耗,相当于减少3 245 t二氧化碳排放;②第三代集成伴热站模块化采购的价格是散材采购加安装费价格的52.67%,具有较显著的经济优势;③第三代集成伴热站模块化采购的方法,交货期仅30 d,可较大程度缩短项目施工周期,具有较显著的时间优势。推广第三代集成伴热站及模块化采购有助于节能、减少二氧化碳排放,并降低采购成本,缩短建设周期。
