| Abstract: | The cavity of stabilizing combustion with twin reflow zones is a device in which stabilized combustion takes place with both external and internal reflow of hot gas. It is simple in construction and much smaller than the pre-combustor in volume, while not subject to agglomeration. Two types of cavity with better structure parameters are presented and the experimental results of the second type in the cold and hot state are analyzed. The design parameters of the cavity are proposed based on test results. The experimental results show that the total volume of gas flow of the twin reflow zones reaches 30 per cent of primary air, and combustion temperature with cavity is higher than that when only a bluff-body combustion stabilizer is used. |
