What are the reasons for the high exhaust temperature in reciprocating compressors?
Thread Content
Dear sea friends, I would like to ask what the possible reasons are for high exhaust temperature in reciprocating engines? Can air valve leakage and coking of the air valve cause high exhaust temperatures?
What you mentioned can cause the valve temperature to rise. Excessive pressure, clogged air valves, broken valve plates, etc., can also cause high temperatures in the air valves.
Insufficient lubrication, excessive pressure, stuck air valves, and broken valve plates can cause high temperatures in the air valves.
Reasons for high exhaust temperature in reciprocating engines: Excessively high compression ratio, high intake temperature, poor cylinder cooling, clogged air intake filter, damaged valves, or leakage in the valve seat gaskets.
One more thing: the inter-stage cooling is not effective
If the displacement remains unchanged, a higher exhaust temperature indicates poor cooling performance
