Hydrogen concentration varies largely in gaseous fuel of an integrated coal gasification combined cycle (IGCC) with carbon dioxide capture and storage (CCS) according to the ratio of carbon dioxide capture. This paper experimentally investigates into the NOx emission characteristics from variation of fuels simulating above hydrogen concentration change. Experiments were carried out using a multi injection co-axial jet burner under atmospheric pressure. From the test results following conclusions are obtained: (1) Minimum NOx emissions were 2.3 ppm for CCS 0%, and 4.6ppm for CCS 90% corrected to 16% oxygen concentration. (2) Stable combustion was obtained by a single burner configuration for each fuel of CCS 0% and 90% without flashback for burner exit temperature ranging from 1200 to 1600℃. This shows the feasibility of achieving a dry low NOx combustion for CCS-IGCC.
