      Soot formation and the effect of soot deposit on the performance and integrity on an aero gas turbine combustor has been studied. Defective atomizer or blockage of air passages creates a fuel rich mixture which promotes soot formation in combustor primary by: 7. The gas turbine industry has become an industry of rapid growth due to its versatile applications and benefits over other methods of power generation. Gas turbines utilize high temperature, high pressure gases exiting the combustor to spin the turbine blades which power the upstream rotating compressor. This energy output may come inCited by: 1.
