Domestic three-stage compression turbines for chlorine production: the outlet temperature at the second stage of compression is higher than that at the first and third stages. Please provide guidance!
The second level being higher than the first should be normal, right? The gap is larger, I guess
Is it because the impeller’s performance is poor? It should be determined by taking into account factors such as temperature, pressure, and equipment vibration
It was like this before, and it’s still like this now. The temperature at which chlorine gas is compressed at the first compression stage is the temperature of the chlorine gas after drying; the temperature of the chlorine gas after drying is relatively low ； The compressed secondary outlet temperature is the temperature after primary cooling and further compression; it is normally higher than that at the primary outlet ； The compressed third-stage outlet temperature is the temperature after secondary cooling and then compression; whether it is higher than that of the second stage depends on the efficiency of the primary cooler.
