Abstract

Combustion properties of coal gasification gas with CO₂ dilution were investigated for a newly proposed IGCC power generation system with CO₂ capture. In this system, the gasification gas was burned under high CO₂ concentration atmosphere. The laminar and turbulent burning velocities were measured for outwardly propagating stoichiometric H₂/O₂/CO₂ flames at the mixture pressures of 0.10 to 0.50MPa. The unstretched laminar burning velocity, u_l and the Markstein number were smaller than those of H₂/O₂/N₂ flames. The ratio of the turbulent burning velocity at the flame radius 30mm, u_tn(30mm) to u_l was larger than that of H₂/O₂/N₂ flames. Increase in the turbulence Karlovitz number and decrease in the Markstein number by the CO₂ dilution might cause the increase in u_tn(30mm)/u_l of H₂/O₂/CO₂ flames.
