How to determine whether there is still room for energy saving in oil-fired boilers?

Strictly speaking, it is the most accurate to determine whether the boiler regulation is appropriate by detecting the boiler discharge, and to determine the burn-out rate of fuel. In practice, regular boiler manufacturers also use this method to debug newly installed boilers.

However, as a user, due to the limitation of equipment (the debugging equipment is special), it is generally calculated according to the size and fuel quantity of the boiler, and at the same time, the intake air volume and fuel quantity are adjusted by observing the chimney with naked eyes. You can also judge whether it is appropriate by observing the flame.

Judging from the phenomenon you mentioned, the coking, blockage and dripping of the boiler oil gun indicate that the oil intake is too large or too small. This needs to be calculated according to the size of your boiler. Of course, the nozzle of the oil gun is coking, and there are other possibilities of blockage, such as the poor oil quality you use, the mismatch between the burner and the boiler (the burner is too large), and the back pressure of the furnace is high.

In your case, I suggest you find someone who knows what happened. Few people here can answer this question for you. I see it once in a while. Let me give you a brief introduction.
