How high is the exhaust temperature of a 1600KW diesel generator?

Your question is too comprehensive. The exhaust temperature of a diesel engine is affected by many aspects, including speed, load, ambient temperature, and if it is water-cooled, water temperature, the usage time of the injector, and what kind of oil is burned. etc. are affected. The exhaust temperature of a general land water-cooled diesel engine with a load of about 85% is generally 300--360 degrees, and that of a marine engine is generally 350--400 degrees. The specific details also depend on the model of the diesel engine. In fact, it is written in the manual.
