摘要
文章以汉中市勉县作为南方非集中供暖区域典型县市,利用陕钢高炉冲渣水的余热作为集中供暖热源,通过对比分析两种不同的余热回收方式,论证了冲渣水余热作为南方城市集中供暖基础热源的技术可行性与经济性。结果表明,直热机余热回收方式虽然能保证供热的稳定性与持续性,但显著增加了换热首站的建设成本和供暖期间的运营成本;宽流道板换便于安装,设备占地面积小,通过进行定期清理与设备保养,能够做到供暖期间稳定运行。因此,针对技改项目、建设用地受限等情况,建议采用宽流道板换方案。
This paper takes Mianxian County of Hanzhong City as a typical county and city in the southern non-central heating area,and uses the waste heat of blast furnace slag water of Shaanxi Iron and Steel Co.,Ltd.as the central heating heat source.By comparing and analyzing two different waste heat recovery methods,it demonstrates the technical feasibility and economy of the waste heat of slag water as the basic heat source of central heating in southern cities.The results show that although the waste heat recovery method of the direct heat engine can ensure the stability and continuity of heating,it significantly increases the construction cost of the first heat exchange station and the operating cost during heating.The wide runner plate is easy to install,and the equipment covers a small area.Through regular cleaning and equipment maintenance,it can achieve stable operation during heating.Therefore,in view of the limited technical transformation projects and construction land,it is suggested to adopt the wide channel plate replacement scheme.
