Analyzing the quality of preparing fuel-air mixture and its influence on NOx in a low emission gas turbine engine combustion chamber

Abstract

The paper presents the results of research carried out to determine the concentration fields in the swirl flow of swirl burners of various design. The burners are used in combustion chambers working on the principle of burning premixed lean air-fuel mixture. The influence of the quality of pre-operation air-fuel mixture on the NOx emission in a gas turbine engine combustion chamber is assessed.
