摘要
Structure of gear-shape (GS) central baffle was put forward for the first time in pulverized coal swirl combustion technology. Profiles of air and particles velocities, particle concentration and particle diameter with a GS central bafle swirl burners had been measured with a three-component PDA system in a gas-particle two phase test facility, in contrast, so did a common baffle swirl burner. Effects of GS central baffle on gas-particle flows had been obtained, influences on burners’ ability had been analysed, and results of the industry use had also been given.
