: I am encountering a low steam to fuel ratio at my boilers averaging at only 11.0 . ( total steam/total fuel.) For info i am using Medium fuel oil.
: Efficiency was also low at only 70 %.
: What are the possible reasons ?? My fuel to air ratio was OK.
: If there is not condensate return back , will it affects this ratio ??
: Thanks inadvance
Have you checked your fuel and steam meters? Are you sure they are correct?
What is your fluegas outlet temperature? As it increased? Maybe your boiler is fouled and needs a cleaning.
success!
