Boiler efficiency questions

We currently use a natural gas fired Fulton steam boiler, whose input is about 900,000 BTU/HR and uses a 12" stack. It's supposed to be a 20 HP unit. We have been considering a 30 HP unit, since 20 HP does not drive the additional presses we recently installed. Our equipment operates at at max of 100 PSI.

However, over the past year, our fuel costs have spiralled out of control.

We are looking at a new high efficiency boiler, hoping that the cost of the unit will be offset by lower fuel costs.

Since I have no idea what the real efficiency of the existing unit is, I can not compare costs with the published efficiency of new boilers.

Does anyone have any idea what the real world efficiency of the exiting Fulton really is?

Any suggestions would be appreciated.

Thank you.
