Flow rate issues in long-distance steam pipeline transportation
Thread Content
Dear experts, I have a question. We purchase steam from an external power plant; the steam outlet pipes at that plant have a diameter of DN800, and orifice flow meters are used. The distance between those pipes and our factory is 12 kilometers. At our factory, there are four flow meters, with diameters of DN500/DN600/DN600/DN700 respectively. The total flow rate measured by these four flow meters does not match the total flow rate measured by the two flow meters at the plant’s outlet There’s a difference of about 3%. Why is that? Heroes, please help me
There is a steam pressure loss and temperature loss of 12 kilometers; in addition, the flow meter itself has an accuracy error of 5%. This tells us that the insulation around the pipeline is quite good, which is why the losses are so low.
