Effect of Nozzle Angle to Combustion Characteristic in Biodiesel Burner

Abstract:

The increasing effort on the environmental impacts of fossil fuel based power generation has led to increased research with the aim of reducing emissions and improving combustion efficiency by turning to alternative fuel such as biodiesel. But the hazardous emission caused by biodiesel is still a problem that need to tackle. One of way to achieve this is by choosing the correct nozzle characteristic. In the current study, the effect of nozzle angle on mixture formation and combustion characteristic are investigate using air-assisted fuel atomizing biodiesel burner. The nozzle angle that was used are θ = 45⁰ and 50⁰. The results show with nozzle 45⁰ produce lower spray penetration, but higher spray angle and spray area compare to nozzle 50⁰. The result are similar on flame development. For the emission characteristic, the Carbon Monoxide (CO) and Hydro Carbon (HC) emission had a strong reduction by using nozzle with 45⁰ angle compare to 50⁰ angle.
