Combustion of Solid Fuels under the Conditions of High Temperature and Various Oxygen Concentration
This work investigated the combustion phenomena of solid fuels, coal and wood pellets with use of high temperature oxidizers (873 -1273 K), both in oxygen diluted and oxygen enriched conditions. The combustion process and flame are described and mass, temperature and heating rate as function of time for different oxidizer compositions and temperature are discussed. The results show that high temperature conditions give the highest mass loss rates. The influence of oxygen concentration on mass loss rate is more evidenced for enriched conditions and/or lower oxidizer temperatures. Diluted conditions are associated with large flames while a typical flame downstream from the sample was almost absent for oxygen concentrations above 50％. Ignition time is highly dependent on oxygen concentration only when a 873 K oxidizer was used while almost independent when a 1273 K oxidizer was used.
