The atmospheric gas burner for a decorative fire has a mixing chamber ( 1 ) closed on an upper side thereof by a burner mat ( 2 ) providing a flame-bearing surface and a pre-mixing burner gas/air supply system ( 4 ) connected with the mixing chamber ( 1 ) on a bottom side thereof. The pre-mixing burner gas/air supply system has a combustion gas injection nozzle ( 5 ) and at least one opening ( 6 ) for supplying primary air. In order to provide a gas burner which is compact, creates a realistic flame impression with high flames and has a small input gas energy as well as a low pressure drop, a small blower ( 8 ) is arranged in the mixing chamber and has a rotor blade or blades ( 8 ) that rotate substantially horizontally in operation.
