Valve temperature calculation
Thread Content
The temperatures at the two ends are different: one end of the DN500 pipe is at 1200°C while the other is at 170°C. How should the temperature after mixing be calculated?
1200 degrees and 170 degrees? It’s a huge difference, right? Are the two runs done on the same medium with the same flow rate? Are you asking about the temperature for valve selection, or the theoretical operating temperature?
There is no material for valves that can withstand 1200°C; some form of local cooling measure will be necessary at the inlet
