The　investigation　of　combustion　phenomena　in　pulverized　coal　flames　is　significant　for　combustion　optimization　related　to　energy　conservation　and　emission　reduction.　Real-time　two　dimensional　(2D)　temperature　and　concentration　distributions　play　an　important　role　for　combustion　analysis.　The　non-contact　and　fast　response　2D　temperature　and　concentration　distribution　measurement　method　was　developed　in　this　study.　The　method　is　based　on　a　combination　of　computed　tomography　(CT)　and　tunable　diode　laser　absorption　spectroscopy　(TDLAS).　The　accuracy　evaluation　of　developed　32-path　CT-TDLAS　demonstrated　its　feasibility　of　2D　temperature　measurement.　32-path　CT-TDLAS　was　applied　to　CH4　and　5　kg/h　coal　combustion　fields　for　2D　temperature　measurement.　The　time-series　2D　temperature　distribution　in　coal　combustion　furnace　was　measured　using　32-path　CT-TDLAS　measurement　cell　with　kHz　time　resolution.　The　transient　temperature　field　of　combustion　flame　directly　reflects　the　combustion　mode　and　combustion　stability.　The　measurement　results　demonstrate　its　applicability　of　CT-TDLAS　to　various　types　of　combustor,　especially　the　combustion　fields　with　coal　and　ash　particles.　CT-TDLAS　method　with　kHz　response　time　enables　the　real-time　2D　temperature　measurement　to　be　applicable　for　combustion　analysis.　©　2020
