У роботi наведено результати експериментального дослiдження впливу 0,1–5,0 масових вiдсоткiв добавок K2CO3 i KCl на дисперснiсть продуктiв згорання газозавису частинок Al (середнiй дiаметр частинок 4,8 мкм) у ламiнарному дифузiйному факелi. Експериментально виявлена екстремальна залежнiсть середнього розмiру частинок Al2O3 вiд концентрацiї добавки (Ca). При збiльшеннi концентрацiї добавки до 0,5% дисперснiсть продуктiв згорання збiльшується (d10 ∼ 50 нм для Ca = 0,5%). При концентрацiї добавки K2CO3 понад 0,5% спостерiгалося зростання середнього розмiру частинок Al2O3 (d10 ∼ 50 нм для Ca = 5%). Показано, що змiна характеру залежностi середнього розмiру частинок Al2O3 вiд концентрацiї легкоiонiзуючої добавки зумовлено взаємодiєю пилової i iонної пiдсистем плазми продуктiв згорання в зонi горiння факела. Проведено теоретичний розрахунок концентрацiї iонiв у системi, при якiй сила iонного захоплення порiвнянна з кулонiвськими силами.

Smoky Plasma in a Dust Flame |
| description |
The results of experimental investigation of the influence of 0.1÷5.0 mass percent of K2CO3 and KCl additives on the dispersion of combustion products, which were obtained by the combustion of an Al gas suspension in a laminar diffusion flame, are presented. The extreme dependence between the average particle size of Al2O3 and the additive concentration (Ca) was experimentally observed. At the K2CO3 additive concentration over 0.5%, the increase in the average particle size of Al2O3 (d10 ∼50 nm for Ca = 5%) was observed. It is shown that a change in the character of dependence between the Al2O3 average particle size and the concentration of low ionizing additives is due to the interaction between the dust and the ion subsystems of the combustion product plasma in the flame combustion zone. The theoretical calculation of the ion concentration in the system, at which the ion drag force is comparable to the Coulomb force, was done. |
