本文设计了采用分级进风方式的旋流燃烧室,建立了湍流旋流燃烧热态实验装置系统。对分级进风旋流燃烧室内的湍流燃烧与NO_x生成进行了实验测量,获得了在不同的分级进风流量比率即二次风率下燃烧室内气体温度和O_2.CO_2、CO与NO浓度的分布。
A swirl combustor with staged air injection was designed. A test facility for swirling turbulent combustion was set up. Measurements of turbulent combustion and NOx formation were conducted in the swirl combustor with staged air injection. The distributions of gas temperature and O2, CO2, CO, and NO concentrations are obtained under different flow rate ratios of the staged air injection or secondary air ratios.
