What are the main hazards of high exhaust temperature in reciprocating compressors?
Thread Content
The exhaust temperature of the first stage compressor in our unit is 110°C, and that of the second stage is 125°C – isn’t that a bit high?
It is necessary to check the design temperature to see if it has been exceeded
It is a bit too high; we are only in the 80s
Let’s see what temperature the valve disc can withstand; the interlock temperature for our hydrogen press was initially set at 135, but it has now been changed to 154
Actually, it depends on the design temperature; compressors for different media have significantly different exhaust temperatures. For example, the exhaust temperature threshold for the CO2 compressors in our factory is around 120°C, while that for the nitrogen and hydrogen compressors is around 160°C; as long as it remains within these limits, there should be no problem
Slightly high; let’s see if the temperature continues to rise. If not, it’s fine.
For hydrogen-rich compressors with a molecular weight of 12 or less, the exhaust temperature should be 135°C or less; for compressors handling ordinary gases, the exhaust temperature should be 150°C or less. A compressor exhaust temperature of 125°C is not a problem.
Overall, I think it’s okay; I’ll observe its operation
Our CNG compressor exhaust temperature alarm range is 145–150℃

First, you need to determine what substance is being compressed by your compressor; for example, if nitrogen is being compressed, the temperature will generally be quite high, while the temperature for substances like BOG is relatively lower. It still depends on the molecular weight of the medium
Harm: High exhaust temperatures can raise the temperature of the cylinder walls and cylinder head, disrupting the proper lubrication of the piston components. This can lead to carbon buildup on the valve seats, as well as damage and jamming of the piston rings in their grooves; in severe cases, this may result in accidents
