The　process　of　direction-change　in　a　certain　high　temperature　air　combustion　retrorse　regenerative　burner　is　simulated　in　this　paper.　With　the　developing　of　time,　the　flame＇s　maximal　temperature　in　the　burner　reduces　gradually,　the　average　temperature　increases,　and　the　temperature　field　becomes　more　even.　With　the　decreasing　of　oxygen　concentration,　the　quantum　of　nitrogen　oxide　concentration　versus　time　minishes,　and　the　reaction　process　is　getting　more　balanced.　With　the　increasing　of　preheated　air　temperature,　the　maximal　and　average　temperatures,　and　the　quantum　of　nitrogen　oxide　also　increase.　But　with　the　reducing　of　oxygen　concentration,　the　influence　of　preheated　air　temperature　on　the　temperature　field　and　outlet　pf　pollutants　become　weak.　As　the　fuel＇s　velocity　is　0.25　m/s　and　0.5　m/s,　the　temperature　field,　nitrogen　oxide　concentration　and　carbon　dioxide　concentration　are　considered　synthetically.
