Combustion properties of coal gasification gas with CO_2 dilution were investigated for an IGCC power generation system with CO_2 capture. In this system, the gasification gas which consists of H_2 and CO, is burned under high CO_2 concentration atmosphere. The turbulent burning velocities and flame shapes were examined for outwardly propagating stoichiometric CO_2 diluted H_2/CO flames under the condition of constant flame temperatures of 1300 and 1700 degrees Celsius. The model of turbulent burning velocity was proposed.
