NUMERICAL STUDY OF DIFFUSION COMBUSTION OF PULVERIZED COAL IN A GAS JET

  • Published:
Journal of Applied Mechanics and Technical Physics Aims and scope

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.
