Working Design Map of Alternative Fuel for High Swirl Burner

Abstract

Gas turbine operation encounters many difficulties in real work. Some of these problems are flashback and blowoff, which are mainly caused by instabilities inside the burner. These phenomena restrict the operation of the gas turbine burner. In circumventing these unwanted phenomena it helps to guess the operative diagram area of the gas turbine combustor. Two types of fuel blends, methane enriched with 15% and 30% hydrogen, have been taken in this investigation to accomplish the required operative pattern plot. Using alternative fuel with hydrogen gives efficient combustion with high energy as hydrogen has higher calorific value and gives low undesirable emissions. These tests were carried out with two different high-swirl numbers. The results show the operation area decreases with high hydrogen content in fuel and with higher swirl number values.
