The　coke　oven　gas　(COG)　which　mainly　consists　of　H2,　CH4　and　CO　is　a　kind　of　feasible　by-product　hydrogen　that　could　be　applied　by　combustion　plants.　This　paper　conducted　experiments　and　numerical　calculations　to　explore　the　combustion　properties　of　COG.　The　laminar　burning　velocity　(LBV)　and　flame　stability　of　COG　with　different　CO/CH4/H2　fractions　were　firstly　tested.　Then,　based　on　the　LBV　results,　a　new　chemical　kinetic　model　was　proposed　and　a　mixing　rule　for　quick　estimating　the　LBV　of　COG　was　acquired.　The　influences　of　different　COG　components　on　LBV　were　obtained.　The　peak　LBV　of　COG　could　achieve　100.2　cm/s　when　the　highest　tested　hydrogen　portion　in　COG　was　adopted　at　an　equivalence　ratio　of　1.2.　Concerning　its　application　in　real　combustion　plants,　the　exhaust　emissions　of　CO　and　NO　from　the　COG　final　combustion　products　were　also　detected　by　an　emissions　analyzer.　The　results　showed　that　raising　the　hydrogen　fraction　in　COG　availed　reducing　CO　at　rich　conditions　through　lowering　the　carbon　fraction.　The　NO　emission　gained　the　peak　value　around　the　equivalence　ratio　of　0.9,　which　was　found　to　be　generally　raised　with　the　hydrogen　fraction　due　to　the　increased　combustion　temperature.　©　2023　Elsevier　Ltd
