Abstract

To obtain how the key characteristic parameters and working conditions affect the combustor ignition performance, experimental investigation on ignition of the coaxial and divisional high temperature rise combustor has been done. The inlet air pressure were 96, 80, 60 and 45kPa respectively, and inlet air temperature was 288K, the ignition performances and boundary lines of different dome characteristics and different liner diameters were obtained at a series of liner pressure drops (1.5%~5.5%). The experimental results indicate that, with the decrease of ambient pressure and the increase of liner pressure drop, for each combustor scheme, the fuel/air ratio at lean lightup increases gradually.Under the condition that other structures remain unchanged, the range of the combustor ignition velocity and ignition boundary were significantly broadened when increasing the dilation angle and height of the dome baffle plate or the liner diameter appropriately.
