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.
