Abstract:
1. A method for adjusting carbon monoxide (CO) emission levels in a boiler system comprising: receiving a first CO level of a first location and a second CO level of a second location; receiving a mass-flow based influence factor map having a first mass flow value indicating a mass flow value of gas emitted from a first burner flowing in the first location, a second mass flow value indicating a mass flow value of gas emitted from a second burner flowing in the first location, a third mass flow value indicating a mass flow value of gas emitted from the first burner flowing in the second location, and a fourth mass flow value indicating a mass flow value of gas emitted from a second burner flowing in the second location; determining whether the first CO level is greater than a threshold CO level; comparing the first mass flow value and the second mass flow value to determine which burner primarily influences mass flow in the first location responsive to determining that the first CO level is greater than the threshold CO level; and adjusting an air fuel ratio of the burner that primarily influences mass flow in the first location responsive to determining which burner primarily influences mass flow in the first location.
