• Combustion properties of coal gasification gas with CO_2 dilution were investigated for a newly proposed IGCC power generation system with CO_2 capture. In this system, the gasification gas was burned under high CO_2 concentration atmosphere. The laminar and turbulent burning velocities were measured for outwardly propagating stoichiometric H_2/O_2/CO_2 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 H_2/O_2/N_2 flames. The ratio of the turbulent burning velocity at the flame radius 30mm, u_<tn(30mm)> to u_l was larger than that of H_2/O_2/N_2 flames. Increase in the turbulence Karlovitz number and decrease in the Markstein number by the CO_2 dilution might cause the increase in u_<tn(30mm)>/u_l of H_2/O_2/CO_2 flames.
