一研究背景 对于大型供暖系统,其运行调节的方法有质调节和量调节。质调节因其良好的水力稳定性为众多供暖单位所采用,但质调节不能降低电耗;量调节虽然节电效果显著,但因需要经常调整循环流量,容易造成水平失调,对管网的调节能力要求相当苛刻,因此国内尚未采用此项技术。 西湖村锅炉房现有29MW锅炉一台,14MW锅炉两台,其供暖方式为间接供暖,下设四个换热站。由于
A research background For large heating systems, the method of operation adjustment is qualitative and quantitative. The quality control is used by many heating units because of its good hydraulic stability, but the quality adjustment can not reduce the power consumption. Although the energy saving effect of the volume adjustment is significant, but it is often required to adjust the circulation flow, it is easy to cause the level of imbalance, the adjustment of the pipe network The capacity requirements are quite demanding, so domestic technology has not yet been adopted. Xihu Village boiler house has one 29MW boiler and two 14MW boilers. The heating method is indirect heating and there are four heat exchange stations. due to
