A burner for a turbine, comprising: a housing, in which an air collection chamber, a combustion prechamber and a combustion chamber are formed, a burner head plate, which is arranged in the housing, so that the burner head plate separates the combustion prechamber from the combustion chamber, a baffle plate, which is arranged in the combustion prechamber so that the baffle plate subdivides the combustion prechamber into a first part chamber adjoining an air supply that is fluidically connected to the air collection chamber and a second part chamber adjoining the burner head plate, wherein the baffle plate comprises a plurality of through-passages, which fluidically connect the first part chamber to the second part chamber, so that air flowed via the air supply out of the air collection chamber into the first part chamber can flow via the through-passages into the second part chamber and flow onto a back surface of the burner head plate facing the second part chamber, wherein the baffle plate extends parallel to the burner head plate, so that air flowed into the second part chamber perpendicularly strikes the back surface of the burner head plate and wherein on the outer circumference of the burner head plate a gap is provided, via which the second part chamber is fluidically connected to the combustion chamber, so that air bouncing off the back surface of the burner head plate can flow out via the gap into the combustion chamber, characterized in that a width of the gap is dimensioned so that a flow velocity of the air on exiting the gap into the combustion chamber is lower than a flow velocity of the air on entering the gap. a housing, in which an air collection chamber, a combustion prechamber and a combustion chamber are formed, a burner head plate, which is arranged in the housing, so that the burner head plate separates the combustion prechamber from the combustion chamber, a baffle plate, which is arranged in the combustion prechamber so that the baffle plate subdivides the combustion prechamber into a first part chamber adjoining an air supply that is fluidically connected to the air collection chamber and a second part chamber adjoining the burner head plate, wherein the baffle plate comprises a plurality of through-passages, which fluidically connect the first part chamber to the second part chamber, so that air flowed via the air supply out of the air collection chamber into the first part chamber can flow via the through-passages into the second part chamber and flow onto a back surface of the burner head plate facing the second part chamber, wherein the baffle plate extends parallel to the burner head plate, so that air flowed into the second part chamber perpendicularly strikes the back surface of the burner head plate and wherein on the outer circumference of the burner head plate a gap is provided, via which the second part chamber is fluidically connected to the combustion chamber, so that air bouncing off the back surface of the burner head plate can flow out via the gap into the combustion chamber, characterized in that a width of the gap is dimensioned so that a flow velocity of the air on exiting the gap into the combustion chamber is lower than a flow velocity of the air on entering the gap.
