Abstract

The residual gas and remained raw gas in dual gas resources polygeneration system are quite complex in components (mainly CH , CO, and H ), and these results to the distinguished differences in combustion reaction. Experimental investigations on basic combustion characteristics of syngas referred above are conducted on a laboratory-scale combustor with flame temperature and flue gas composition measured and analyzed. Primary air coefficient (PA), total air coefficient (TA), and components of the syngas (CS) are selected as key factors, and it is found that PA dominates mostly the ignition of syngas and NO formation, while TA affects the flue gas temperature after high temperature region and NO formation trend to be positive as H /CO components increase. The results provide references for industrial utilization.
