某集中供热系统运行调节方式分析

The analysis of the operational regulation mode in the system of district heating

简单介绍了各种集中供热运行调节方式的特点,针对3种典型的运行调节方式,推导出相应的参数调节模型;以某集中供热系统为例,结合当地气象条件,计算出3种调节模型在该区采暖期运行调节中的具体数值;最后对各调节方式在经济性,包括运行费和初投资方面作了比较。通过分析,指出质调与流量改变的调节方法在电耗、经济性方面存在着明显的差异,推荐采用流量改变的调节方式,尤其是质-量并行的量调节方式更应积极推广。

Various modes of operational regulation in district heating simply were introduced. Relevant parameter models were educed aiming at 3 typical regulation modes. The concrete values of parameter models in operational regulation mode were calculated by taking a district heating project as example. Finally, some simple economic analyses for various regulation modes were carried out. According to these discussions, it was pointed out the difference between the regulation by changing temperature and by changing flux in district heating. The energy is supplied indirectly by district boiler; the regulation by change flux was proposed for the regulation by changing temperature and flux contemporary.
