摘要
变异煤粉浓度燃烧器解决了劣质烟煤的着火和稳燃的问题，文中首次公开该燃烧器的关键部件——浓缩器（扭叶片）的阻力特性试验研究结果，扭叶片单相空气流动阻力系数气为３．２３θ－０．５５９Ｒｅ－０．２；而气固两相流动阻力系数ξｇｓ为（０．１３５μ＋１）ξｇ。
The burners with distorted pulverized-coal concentration have solved the problem oflow-grade bituminous coal ignition and combustion stabilization. This paper releases for thefirst time experimental results of resistance characteristics of pulverized coal concentrators(twisting blades)which are the major parts of this kind of burners, Resistance coefficient ex-pression of twisting blades with single-phase air flow is ξg=3. 23θ-0.559 Re-0.2 and that of gas-solid two phas eflow is
