Combustion air is fed into the air part of the burner via the combustion air pipe. It usually flows completely between the recuperator and the combustion pipe, during this the air is warmed by the hot off gases which flow back on the outside of the recuperator. The largest part of the warm combustion air flows through the incoming air bore holes into the inside of the combustion pipe and then through the twist plate into the combustion chamber. It is mixed here with the combustion gas, the smaller part of the combustion air the secondary air flows through the annular gap between the combustion pipe mouth and the recuperator, the mixture of the air with the outgoing flame gases leads to complete combustion, the sir plate divides the combustion air volume flow. One part may take the cooling air path inside the combustion pipe, depending on requirements the technical firing level of efficiency and the mission of nitrogen oxides can be influenced, the simultaneous cooling of the gas lance has benefits when operating the burner near its top temperature, the combustion gas flows via the connection pipe to the gas part and through the gas pipe to the twist plate, the largest part of the gas volume flow passes through the radial oriented openings into the combustion chamber and mixes with the combustion air.
