Description
Summary:In the present study the combustion characteristics of an non-pre-mixed fuel (Syngas) in around jet-burner were investigated numerically. The reduction of exhaust pollutants and increase in the rate of combustion was the primary goal of the present study. The world is facing energy crises of fossil fuel which are going to be extinct very soon which causes global warming and different kinds of health hazards, so as an alternative to gasoline, Syngas has been used which is environment friendly. The fluid flow and thermal analysis has been done using COMSOL Multiphysics to analyse the combustion characteristic in non-premixed burner. The most efficient compositions, the rate of combustion, thermal efficiency was determined. The effect of composition of Syngas, pipe inner diameter, Jet velocity, Co-flow velocity, on exhaust gas characteristics and on combustion efficiency was analysed. The velocity variation and flow path(streamline) of reacting jet, temperature profile in jet, CO2 mass fraction in reacting jet, axial velocity at downstream of the pipe exit, species mass fraction on the jet centreline were analysed to study the effect of input variables on the combustion characteristics.
