Radiation intensity and emissivity measurements were made for a DF-2 flame in a model gas turbine combustor. This same flame was also mapped lor temperature and soot mass concentration. Finally. a movable, cold traversing background was used to determine the contribution to total radiation intensity

β¦ Synopsis
Broadening of liquid fuel specifications decreases the hydrogen content and increases the aromatics and final boiling point. The cumulative effect is an increase in soot formation and hence in flame radiation, which affects the durability of combustor flame tubes. Empirical formulae are developed for luminosity, radiation and convection under idling and full load conditions. These equations predict combustor liner temperatures agreeing well with previous experimental data.

The trends towards using heavier fuel oil in the gas turbine engine will increase the soot formation rate in the primary zone, which increasesflame radiation and impairsflametubedurability. Therefore, devising a method to determine quantitiatively the soot concentration is of paramount importance,
The transient response of a monolith catalytic combustor to changes in operating conditions and monolith design parameters has been examined on the basis of a mathematical model. The model considers both catalytic and gas phase reactions and allows for axial conduction of heat in the solid substrate
With lower costs and greater availability, heavy fuel oil appears as an attractive alternative to the conventional gas oil used in industrial gas turbines. However, higher levels of radiation and smoke are expected, and this note reports on some preliminary tests made with a combustion chamber burni
