Liquid Fuel Double Swirled Combustion with Gaseous Fuel Injection

Abstract

The experimental work was proceeded to investigate the effect of the cross flow (opposing jets) as gaseous fuel with merged to the effect of the double swirling on the performance of the diffusion flame. The cross flow was used as opposing jets (as premixed mixture of gaseous fuel and air). And the influence of the double swirler on the flames was stated with swirling modes as (Co or Counter) swirl. The goal from this experiment was to improve flame stability, but the combustion efficiency kept at high values and also reduced the NOx emissions values and minimize also the values of the unburned hydrocarbon as well as the carbon monoxide. The experiment parameters was the ratio of the momentum flux, swirl intensity and the angle of the swirling vanes and also the ratio of the obstruction stream heat input, The strain rate significantly influences the limits of the flame stability, and the flow strain features was addressed by the turbulent kinetic energy. Because the increasing power required a combination with the regulation of the environmental, so the combustor design search for improving the firing technique to increase the power output with extending the limits of the flame stability. A mixture between the passive and reactive control technique is used for achieving these targets.
