To design a practical gas turbine combustion chamber which operates up to 55 atmospheres, burning stability at elevated pressure was investigated by can type combustion chambers with different prirr.ary zone designs. It was found that there is strong correlation between average air velocity in the primary zone at the blow-off limit U_<BO> and laminar burning velocity S_L of the methane fuel. At atmospheric condition. At high pressure condition, however, U_<BO> can be correlated with the maximum laminar burning velocity S_lt:LM> corresponding to the pressure and the temperature. Values of U_<BO> /S_<LM> for three combustors investigated have same correlation with operating pressure. The result shows that the air velocity in the primary zone must have lower values as the design pressure increases.
