Hello everyone. Could anyone help me with methods for increasing the run length of natural draft furnace?

 

[PingPong]

Runlength of a furnace is determined by what happens inside the tubes (coking, fouling, ....),

not whether the furnace is natural draft or forced draft or induced draft.

What exactly you want to know? What type of furnace are you operating? Is it a reboiler for Crude or Vacuum distillation column or a Naphtha/Ethane/Propane cracking furnace?

 

Then a good discussion can be started.

 

RIL has good documentation. You can find some info in-house too.

Run length not only depends on what happens in the tubes. Mixing efficiency at burners and draft at arch also count.
Now to respond to the OP question, I would say daily visual checking (flue gas temperature, excess O2, burners tips pressures, fuel flowrates, tubes color, possible air ingress in the convection zone), performance follow-up (thermal efficiency) and periodical in-line cleaning are key to extend run length.
