对三级旋流器燃烧室进行了常压试验研究.研究首先设计研制了三级旋流器燃烧室模型和试验系统,然后在此基础上开展了不同进口速度、进口温度和油气比等参数影响三级旋流器燃烧室的流阻特性、点火特性、贫油熄火特性和燃烧效率特性等性能的试验研究.结果表明:该三级旋流器燃烧室可以在不同试验工况下顺利点火和稳定工作,点火性能基本不受进口速度的影响;总压损失系数随进口速度的增加而增大,而流阻系数随速度的增加而减小,燃烧室流动未进入“自模状态”;随着进口温度的增加,点火、贫油熄火性能变好,燃烧效率提高.
Atmospheric pressure test of the three-stage cyclone combustion chamber was carried out.At first, a three-stage cyclone combustion chamber model and test system were designed, and then different parameters such as inlet velocity, inlet temperature and gas-oil ratio The experimental results show that the combustion chamber of the three-stage cyclone can successfully ignite under different test conditions, which affects the performance of three-stage cyclone combustor in terms of flow resistance, ignition characteristics, lean blowout characteristics and combustion efficiency characteristics. And stable operation, ignition performance is basically not affected by the import speed; the total pressure loss coefficient increases with the increase of the inlet velocity, while the flow resistance coefficient decreases with the increase of the velocity, the flow in the combustion chamber does not enter With the increase of the inlet temperature, the ignition and lean oil turn-off performance becomes better and the combustion efficiency improves.
