I have a ABC 6 piston diesel turbo charged engine (950 KW) ,when we usually load the engine to around 750 KW (500C)the exhaust manifold and the turboinlets manifolds become red hot,we contacted the manufacturers they said the pipes can withstand the temperatures but I think this should not happen as red hot means it is getting too much hot why is this happening.The engine is a dual fuel pilot is diesel fuel.When we run it on diesel the temperatures fall down the red hot colour disappears but when we switch it to dual fuel where the secondary fuel is natural gas the exhaust becomes red hot.

The natural gas flow is controlled by an electronic actuator accorindingly to the load requirements no special equipments attached as for the air flow I dont know the exact flow.

Is it safe to operate when the exhaust manifolds are getting red hot.
