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 (S) 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 (S) into the combustion chamber , characterized in that a width of the gap (S) is dimensioned so that a flow velocity of the air on exiting the gap (S) into the combustion chamber is lower than a flow velocity of the air on entering the gap (S). 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 (S) 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 (S) into the combustion chamber , characterized in that a width of the gap (S) is dimensioned so that a flow velocity of the air on exiting the gap (S) into the combustion chamber is lower than a flow velocity of the air on entering the gap (S). <EOS>
