摘要：

In　this　paper,　numerical　investigations　on　flammability　limit　of　axisymmetric　count-flow　laminar　diffusion　flames　of　CO,　CH4　mixed　fuel　were　conducted　by　using　the　detailed　kinetic　mechanism　(GRI-Mech　3.0).　The　peak　flame　temperatures　of　the　flames　with　different　mole　fractions　of　CO　and　strain　rates　were　obtained,　and　the　influence　of　the　variation　of　αCO　and　strain　rates　on　flammability　limit　was　understood.　Then　the　effects　of　main　factors　on　flame　characteristics　were　studied.　It　is　found　that　the　flame　temperature　decreases　obviously　with　increasing　strain　rate.　The　formation　rate　of　OH　is　reducing　along　with　the　increasing　αCO,　which　leads　to　the　decrease　of　the　flame　temperature,　as　well　as　the　combustion　intensity.
