Issues regarding the transfer of steam condensate
Thread Content
The workshop has carried out modifications to the steam condensate system; the results of these modifications are shown in the diagram. At this stage, it is necessary to determine the pressure within this pipeline. Although local pressure gauges have been installed on site, we believe that the values displayed do not accurately reflect the issues present. We are looking for a calculation method to determine the pressure.
Will the calculations be more accurate than the measurements? It’s interesting to analyze whether the design is reasonable; also, how can pressure surges be avoided in the event of a failure in the water-repellent valve?
Can the steam pressure reach the rated value?
The pressure here is related to the back route; where does the condensed water go?
I don’t understand what DN25 refers to in this diagram. As a side note, there’s actually a question regarding this topic; it would be best to ask the designer.
It’s better to install a gauge. If the steam trap doesn’t work properly, pressure build-up can occur very easily; it’s not recommended to combine so many systems with high pressures together
It is recommended to provide separate collection tanks for steam condensates at 3.7 MPa and 2.5 MPa; these condensates should then be depressurized and flashed to 0.6 MPa in order to recover some of the flash vapor, after which the resulting condensed liquid can be integrated into the pipeline network.
