Response Measures for Over-temperature Return Water of Long-distance Heating Network under Accident Conditions
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.
