In Reply to: Need combustion efficiency charts. posted by Mike Hinz on April 13, 2000 at 13:11:33:
: The combustion efficiency charts we have been using were fine for our plant, but several years ago we began remote monitoring of another, smaller plant. Our old charts only go to 250 degrees F, and on light loads the flue gas of the remote plant often drops below this. Nobody around here has the slightest idea where to obtain charts with readings lower than 250 degrees. Any suggestions would be useful.
Why wouldn't you assume that the temperatures you are measuring (250) indicates that the burner is not firing and that the temperatures are ambiant + stack temperature of the natural drafted heat from the boiler?
