Thus if, for example, an energy manager wishes to check the current performance of a furnace, improve its maintenance, and explore options to upgrade its physical design, most likely the expertise to drive all of these improvements resides in the same individual or group.
An evaluation by a fired heater SME may find, for example, that the fired heater may only be able to safely achieve 3.5% excess O2 due to a sticking stack damper.
As a result of this finding, the interim operating target for excess O2 may be set at 3.5%.
However, if the sticking damper can be rectified, the SME may determine that the excess O2 could be reduced to 2%. This triggers maintenance activities. Finally, the SME may determine that an additional convection bank can be added to the furnace.
This would lower the stack temperature, and has significant energy-saving benefits.
This leads to a capital project to upgrade to furnace.
