CAUTIOUS OPTIMIZATION STRATEGY FOR EMISSION REDUCTION

摘要

A system of controlling combustion of fuel in a boikr having an adjustable air-to-fucl ratio. A first senior is used to measure the CO production to provide a CO distribution range during a period of time for the combustion. A second sensor measures the NO, production to provide a NO, distribution range during this period of lime for the combustion. A controller adjusts the air-to-fuel ratio to cause combustion of the fuel within the CO distribution range and the NO* distribution range to thereby cause the actual emission for the CO and NO, distribution* to average less than the maximum permitted Preferred time ranges are from
