Fuel Spray Evaporation in Gas Turbine Burners.
Abstract
The rate of evaporation from a liquid fuel spray is one parameter which is almost universally overlooked when an overall gas turbine design is attempted. A computer program has been developed to estimate the rate of evaporation from a fuel spray, using a method which involves the entire spray. A drop size distribution divided into a number of size intervals, each represented by its own droplet diameter was used to model the known characteristics of spray combustion. The experimental rig was used to provide data essential to the computer program. Gas temperature measurements within the combustor showed the prevailing air flow patterns and the existence of a zone of high temperature gas in the region of evaporating fuel. Gas velocities were calculated from measurements of inlet air pressure and droplet velocities were estimated to give necessary data on relative velocities. This enabled the effects of force convection to be included in the program. (Modified author abstract)
