摘　　要：集中供热是保障我国人民生产生活的重要基础能源设施。我国城镇化进程的快速推进以及国家节能减排、环保等一系列政策的出台,北方城市的传统供热模式发生了很多变化。拆并小锅炉、多热源联网运行等措施的实施,使得城市供热系统的规模不断扩大,供热管网变得越来越复杂,系统运行调节花费的时间更长。相对于新建热网而言,原有老旧管网供热设备设施质量较差,加之从事专业技术人员的实践经验不足,导致在供热系统投运初期易出现水力不平衡、调节滞后、能耗大、用户室温冷热不均和投诉等问题。如何采取有效的措施保证老旧管网并网后整个供热系统的可靠性和经济性,降低供热风险,是当前热力企业重点研究和解决的问题。Central heating is an important energy infrastructure to ensure the production and life of our people.The rapid advancement of China’s urbanization process and the introduction of a series of national policies on energy conservation, emission reduction and environmental protection, many changes have taken place in the traditional heating mode in northern Cities of China.Splits and small boiler, heat source more networking operation, the implementation of the measures such as, urban ring network heating and multi heat source combined heating makes the scale of urban heating system continue to expand, the heating pipe network becomes more and more complex, and the system operation and regulation takes longer.Compared with the new heating network, The quality of heating equipment and facilities of the original old pipe network is poor, coupled with the lack of practical experience of professional and technical personnel, which leads to the problems In the initial stage of operation of heating system, there are many problems, such as hydraulic imbalance, regulation lag, large energy consumption, uneven cooling and heating at room temperature and complaints at the initial stage of operation of the heating system.How to take effective measures to ensure the reliability and economy of the whole heating system after the old pipe network is connected to the grid, and reduce the heating risk, is the focus of the current thermal enterprises.
