  • To provide a valuable theory basis for the structure design of the advanced vortex combustor (AVC) of the turbine in integrated gasification combined cycle (IGCC),experiment and numerical simulation were conducted to study the flow characteristics of the AVC under cold flow condition.On this basis,the reasonable arrangement of fore-body and after-body in the AVC with hydrogen fuel was attained.Using 19-step chemical reaction mechanism,a numerical simulation was conducted to study the flow and combustion characteristics of AVC with hydrogen fuel.The results show that the combustion can be steadily maintained,and the temperature at the outlet can be controlled below 1950K with the equivalence ratio of hydrogen and air being kept at 0.65 without gas injected into the cavity between fore-body and after-body.At the same time,there are total pressure loss coefficient of 2.7665% and combustion efficiency of 99.54%.Contrasting to the AVC without gas injected into the cavity,the AVC with flow injected has more regular and steadier vortex configuration,higher combustion efficiency,higher total pressure loss coefficient,and uneven temperature distribution at the outlet.
