Abstract

Abstract: From the angle of engine combustion performance,the influence of the alternative fuel on combustion performance after the aeroengine changed into floor combustion gas turbine was researched.FLUENT,fluid computing software,was used to compute different alternative fuels on the combustion properties.For the floor combustion gas turbine combustor in the burning of aviation kerosene,light diesel oil,industrial fuel alcohol and natural gas,simulation was carried out,and the engine combustion performance of different fuels was given.The result showed that,from the angle of engine combustion performance,there was no difference between aviation kerosene and light diesel oil,which can be used directly or combined with aviation kerosene by engine combustor.The emission of NOx and CO from natural gas combustion was 1 000;natural gas is an ided low-emission fuel.There was a wide gulf between the aviation kerosene and the industrial fuel alcohol,which needs an in-depth study for the technology on changing fuel from aviation kerosene to industrial fuel alcohol after the aeroengine changed into floor combustion gas turbine.The research has a valuable reference for the development of the next generation of aviation alternative fuel.
