The present work is dedicated to the experimental investigation of the influence of fuel-type and oxidizer composition upon flame structure and behaviour of swirl-stabilized pulverized coal flames. Detailed flame measurements are conducted by employing a combination of flame-intrusive and non-intrusive measurement techniques which can provide complementary data about flow fields, major product species and radiative heat transfer from the flames....
