Influence of Fuel Molecular Composition Upon Flame-Tube Temperature and Flame Radiation in a Model Gas-Turbine Primary Zone

摘要

Fuels containing known concentrations of well-defined hydrocarbon types were burned under conditions simulating those occurring in aviation gas turbine engines. The values of flame tube temperature and flame radiation were compared to predicted values. Results indicate that aromatic content is inappropriate as an inspection property for fuels containing fused bicyclic saturated hydrocarbons; that hydrogen content is a satisfactory inspection property for fuels containing simple aromatics and fused bicyclic saturated hydrocarbons; and that only smoke point is a satisfactory inspection property for fuels containing high concentrations of tetralins and naphthalenes. A kinetic explanation for the observed results is proposed.
