A comprehensive 2D model of an industrial Natural gas (NG) non-catalytic partial oxidation reformer is established.
Both the modified EDC model and the PDF model are used to model the turbulence-chemistry interaction.
The results of the modified EDC model agree better with the industrial operating data.
The increase of pressure promotes CH4 conversion and a pressure higher than 3.0 MPa is suggested for industrial operation.
The O2/NG mole ratio range of 0.66–0.67 is optimal according to the yield of the H2 and CO.
