摘要
通过管网模拟技术建立管网数学模型,提出了基于模拟技术的蒸汽管线散热损失分析评价方法,这种方法有效地对蒸汽管线散热损失进行了量化,克服了通用方法的不足。用该方法分别对压力等级为12.0 MPa(SS)、4.0 MPa(HS)的蒸汽管网进行了散热损失评价,并进行了管网保温改造,同时把该方法推广到中原石化全厂的蒸汽管线,取得了蒸汽系统节能的预期效果。
Based on pipeline network simulation technology, this paper puts forward a evaluation method of steam pipeline heat loss, which has established mathematical model of comprehensive quantitative pipeline heat loss and overcome the disadvantages of common methods. The evaluation method has been applied to heat loss analysis of the whole steam networks in Zhongyuan Petrochemical, and effectively improved the level of energy saving of the steam system.
