区域型锅炉房作为调峰热源的可行性分析

Feasibility Analysis of Small and Medium Sized Boiler Room as Peak Load Regulating Heat Source

当前城市热网和热源存在诸多问题,例如热网输送能力不足,热源运行达不到设计值,大型调峰热源不能对负荷变化进行频繁及时调整等。针对这些问题可以考虑利用区域型锅炉房作为调峰热源,热电联产作为主要热源并联合供热的方式进行供热。确定了区域型锅炉的调峰负荷,对比了不同调峰系数下的寿命周期费用,计算得出区域型锅炉开启的室外温度。结果表明:利用区域型锅炉房作为调峰热源具有良好的经济优势。

Many problems exist in city heating source and network such as low transmission capacity, inability to reach the expected value for the operation of heat source, impossibility to adjust the load of large peak heat source timely and frequently, etc.. In view of this, medium and small boilers could be considered the peak load regulating heat source and CHP the main heat source to have the combined heating supplies. The peak load of medium and small boilers has been determined, the life cycle costs of different peak shaving coefficients have been compared and the outdoor operation temperature for the medium and small boilers has been worked out. Results show that the new scheme is more economic.
