Numerical Investigation of the Process of Peat Gasification in an Oxygen-Enriched Vapor–Air Mixture in a Fixed Bed under a Pressure of 1.5 MPa

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

A two-dimensional system of parabolic and hyperbolic equations has been constructed describing the aerodynamics, heat and mass transfer, and chemical reaction of a gas-dispersion medium in a fixed bed. An investigation has been made into the effects of particle motion velocity and H2O content in a vapor–air mixture on the temperature and concentration phase fields, unburned carbon loss, grate slagging, steadiness (stabilization) and stationarity of the gasification process, and the calorific value of synthetic gas. An original method has been proposed for the supply of coal dust into the burners using generator (producer) gas as a working medium ejecting fi ne dust.
