Burning velocities and flammability limits of gaseous mixtures at elevated temperatures and pressures

Burning velocities and flammability limits of gaseous mixtures of combustible gas (hydrogen and methane), oxidizer (oxygen and air), and diluent (nitrogen, argon, helium, carbon dioxide, steam, water aerosol formed by evaporation of superheated water) have been measured at elevated temperatures (up to 250°C) and pressures (up to 4.0 MPa). It was found that with increasing temperature, the flammability region is widened for all the mixtures...
