摘要
结合实际运行情况,对事故工况长输热网超温回水应对措施进行探讨.提出通过并联隔压站一级侧流量调节,利用正常运行的隔压站回水与故障隔压站超温回水进行混合,控制总回水温度不超出安全范围.实际应用显示,该方法可有效消纳留存在回水管中的超温回水,确保长输热网与电厂安全运行.
Abstract
Combined with the actual operation situation,the response measures for over-temperature return water of long-distance heating network under ac-cident conditions are discussed.It is proposed that through the flow regulation of the first-level side of the parallel pressure isolation station,the return water of the normal pressure isolation station and the over-tem-perature return water of the faulty pressure isolation station are mixed to control the total return water tem-perature within the safe range.The actual application results show that the method can effectively absorb the over-temperature return water remaining in the return pipe,and ensure the safe operation of the long-distance heating network and the power plant.
