摘要:
A combustion device (10) includes at least one combustion chamber (11) with a plurality of burners (B1, . . . , Bn) operating in parallel which produce in each case a flame (F1, . . . , Fn) which reaches into the combustion chamber (11), wherein each of the burners (B1, . . . , Bn), via a fuel distribution system (18), is supplied with a fuel from a fuel supply (16), which fuel distribution system (18) includes control elements (V1, . . . , Vm) for manual or controlled regulating of the fuel supply and/or fuel composition of individual burners (B1, . . . , Bn) and/or groups of burners (B1, . . . , B3; Bn−2, . . . , Bn). In a method of using the combustion device, a quick optimization or homogenization is achieved by a function (F) of the flame temperatures of the burners (B1, . . . , Bn) being provided in dependence upon the positions of the control elements (V1, . . . , Vm) of the fuel distribution system (18), which function has been calibrated by measurements of the flame temperatures at a plurality of predetermined positions of the control elements (V1, . . . , Vm) of the fuel distribution system (18), and in that by the calibrated function (F) the positions of the control elements (V1, . . . , Vm) of the fuel distribution system (18), which are optimum for a predetermined distribution of the flame temperatures of the burners (B1, . . . , Bn), are determined and adjusted.

摘要:
A premix burner is disclosed for operating a combustion chamber with a gaseous and/or liquid fuel, having a swirl generator for inducing a swirl flow in an incoming combustion air flow and a device for injecting fuel into the swirl flow, the swirl generator having at least two cone shell segments which fit together to form a flow body and together enclose a conically formed swirl space with a cone angle γ and air inlet slits directed tangentially to the length of the cone. At least at the downstream end region of the swirl generator, a shaped element enclosing the cone shell segments with an inside wall facing the cone shell segments is provided, and that the cone shell segments end in the inside wall in a flush manner while maintaining their shape.
