Regarding the issue of high exhaust temperature in liquid-injected screw compressors
Thread Content
We are using a spray-type screw compressor of the Dalong LG-593/7 model, with coke oven gas as the medium being transported. The alarm threshold for exhaust temperature is 95 degrees Celsius, while the interlock value is 100 degrees Celsius. During operation, the temperature often stays around 96 degrees Celsius, remaining high without dropping. Additionally, there is significant water in the exhaust gas. We would appreciate it if experts could analyze this situation
Are there any specific operating parameters, such as suction pressure, suction temperature, exhaust pressure, etc.? Could it be that the suction temperature is too high or that there isn’t enough cooling water? If none of these are the issues, then internal abrasion might be the cause. Also, when it is said that water is present in the exhaust, does this refer to water in the compressor’s exhaust or in the entire unit’s exhaust?
