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, ul 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, utn(30mm) to ul 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 utn(30mm)/ul of H2/O2/CO2 flames.
