This chapter presents the development of emissions controlling technique for oil and gas burner especially to reduce oxides of nitrogen (NOx). Other emission of interest is carbon monoxide (CO). In this research liquid fuel burner is used. Five different radial air swirler blade angles have been investigated using 163 mm inside diameter combustor of 280 mm length. Tests were conducted using kerosene as fuel. A radial flow air swirler with straight blades having 40 mm outlet diameter was inserted at the inlet plane of the combustor to produce swirling flow. Fuel was injected at the back plate of the swirler outlet using central fuel injector with two fuel nozzles pointing axially outwards. The swirler blade angles and equivalence ratios were varied. Tests were carried out using three different air swirlers having 30°, 40°, 45°, 50° and 60° blade angles, respectively. A NOx reduction of more than 28 percent was achieved for blade angle of 60° compared to the 30° blade angle. CO emissions were also reduced by 40 percent for 60° blade angle compared 30° blade angle.
