摘要
在集中供热系统二级网侧设置燃气锅炉作为调峰热源可改变供热管网系统的事故状态.针对二级网调峰供热系统的特点,得出了热网系统可靠性指标的计算方法.分析了调峰热源对热网可靠性指标的影响,并通过实例计算了在不同基础负荷系数下二级网调峰集中供热系统的可靠性指标.结果表明,选择适当的基础负荷系数,在热网元件出现故障时,调峰热源能实现限额供热状态,起到备用热源的作用.
The fault condition of the heating networks would be changed by the gas-fired boiler set in secondary networks of district heating（DH） system as peak load regulating boiler. Aiming at the characteristic of the DH system, a method to calculate the reliability index of heating networks was presented. The impact of peak load regulating boiler on the reliabihty index was discussed. Reliability indexes of a case with various base load ratios were calculated. The results show that with a proper base load ratio, peak load regulating boiler could work as a standby heat source to keep system in limited heating condition, when failure occurred in the components of the heating networks.
