NOx emission characteristics of four basic types of experimental burners firing kerosene-type fuel at rates up to 110 lb/hr were investigated experimentally. Emission levels were found to be highly dependent upon primary-zone temperature and air-fuel ratio, but independent of firing rate and residence time over a 10:1 ratio. This independence of residence time is in marked contrast with results from simple burners used in fundamental research. The burner with the lowest NOx emission level used a cooled, rich primary zone and a lean secondary zone. Although the work was aimed at automotive Rankine-cycle systems it appears applicable to other compact combustors.
