双热源联网集中供热系统运行方案的选择及实际应用

双热源或各热源联网运行是当前或今后城市集中供热的发展方向，我国许多城市均设计了热电厂与锅炉房联合供热方案，但是绝大多数仍为独立运行，没有实现多热源运行方式。本文介绍了包头市昆区集中供热系统联网运行方案的优化过程，确立了理想运行工况。该方案在95－96采暖期应用后，我们对理想运行方案下的实际运行结果进行了分析比较，实践证明该方案是可行的，由此得出了双热源供热系统比单热源供热系统安全可靠、便于调节的结论。

The dual or multiple heat source network run-ning will the development orientation of urban con-centrated heating of today, even in the future. Al-though the design on heating made jointly by ther-mal power stati0ns and boiler r0oms has been ex-ecuted in many cities of China, 0nly independentrunning, 0ther tha11 multiple heat s0urce run11il1gmode, is realized in most 0f the said cities. The 0pti-mizing process 0 the running design on concentratedheating system by networking in Kundulu11 Dis-trict, Baotou is described herein, in which a1l idea1working condition in running is establishetI' Afterthe design was applied in f 95 to' 96 heating I>eri-ods, the ideal running design and the actual rLlnningresult were analysed and comparcd with each othcr'The fact pr0ves tl1at both the design and the idea1working c0ndition in running are right and feasible.The obtained conclusi9n te11s that the dual l1eatsource heati11g systeln is much safer nnt1 more reli-able and easier to adjust than the single heat sourceheatil1g system.
