Experimental and Numerical Study of Co-firing Peat with Syngas in a Vortex Burner

Abstract

Experimental and numerical study of co-firing peat with different gaseous fuels in the vortex burner are carried out. At the “lean” operational regimes co-firing peat with syngas is more effective and allows to organize reliable ignition and stable combustion at the values of excess air coefficient up to αΣ = 2.7. In addition, co-firing with syngas requires less initial methane to produce it applying catalytic reforming than direct co-firing with methane. Also, syngas supply into vortex burner allows to reduce combustion temperature and emission of NOx.
