Effect of Arene and Naphthene Concentration on Spray Characteristics of Biomass Jet Fuel

Abstract

Arene and naphthene are pyrolytic products in the preparation of biomass fuels and the main ingredient of jet fuel China RP-3. Biomass fuel has the advantages of reducing greenhouse gas emission and reducing fuel cost, it is necessary to develop the research and application of biomass fuel. This work investigate the influence of arene and naphthene concentration on the spray characteristics of jet fuel China RP-3 using a hollow cone pressure swirl nozzle The cone angles and sheet breakup length were measured at injection pressure of 0.3,0.5,0.7 and 0.9MPa using shadowgraph system. In the same injection pressure, to add up ethylbenzene concentration will bring down the cone angle and increase the breakup length and to add up ethylcyclohexane concentration will increase the cone angle and bring down the breakup length. For both of ethylbenzene and ethylcyclohexane the effect of concentration on cone angle is no more than 8% and on breakup length is no more 16%. While the influence of injection pressure could reach up to 15% and 67% for cone angle and breakup length.
