Abstract

Adaptation of a mathematical model of gas diffusion combustion for different flow rates of CO–H₂ and a constant coal flow rate is carried out. It is shown that the results of calculating the main characteristics of the flame are in satisfactory agreement with experimental data and can be used to determine the structure of pulverized coal–gas flow, gas composition, particle and gas temperature, carbon combustion efficiency, etc. The proposed model is suitable for analyzing the stability of coal–gas flame and the transient processes accompanying changes in the mode of supply of the fuel-oxidizer medium.

煤粉在燃气射流中扩散燃烧的数值研究

摘要

针对不同的 CO-H ₂流量和恒定的煤流量，对气体扩散燃烧的数学模型进行了调整。结果表明，火焰主要特性计算结果与实验数据吻合较好，可用于确定煤粉气流结构、气体成分、颗粒和气体温度、碳燃烧效率等。所提出的模型适用于分析煤气火焰的稳定性和伴随燃料-氧化剂介质供应方式变化的瞬态过程。
