Effect of Mixture Formation of Biodiesel-Water-Air Rapid Mixing Derived from Crude Palm Oil and Waste Cooking Oil in Burner Combustion

Abstract:

The trade-off between NO_x and PM is a main issue in the observation of combustion characteristics, NO_x and PM are released from the combustion of biodiesel either in internal combustion engine or external burner system. Thus, the rapid mixing of biodiesel-water-air technique is one of the most significant approaches to the reduction of pollutant emissions of burner combustion. In this research, the relation between the mixture formation of biodiesel spray and burning process was investigated in detail in order to understand the effects of the changes of fuel properties in fuel evaporation. In these experiments, different types of biodiesel fuel derived from the crude palm oil and waste cooking oil were used in the same nozzle characteristics of burner system. This study focuses on the observation of the real images of the spray characteristics together with equivalent ratio, water content, spray penetration length, spray angle and spray area. Water emulsion of percentage up to 15vol% and blending of biodiesel ratio was varied from 5vol%-15vol%. The diesel fuel have been compare with based analyzed of real spray images with the times change. The results shows percentage of biodiesel and shows the higher of water content due to the higher viscosity affects the higher penetration length and lower spray angle and influence the flame penetration.
