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. |

1. A method for operating a combustion device, the combustion device including at least one combustion chamber with a plurality of burners operating in parallel which each produce a flame which reaches into the combustion chamber, wherein each of the burners, via a fuel distribution system, is supplied with a fuel from a fuel supply, which fuel distribution system includes control elements for manual or controlled regulation of the fuel supply and/or fuel composition of individual burners and/or groups of burners, the method comprising:
determining a function (F) of the flame temperature of the burners for homogenization of the combustion device in dependence upon the positions of the control elements of the fuel distribution system, the function (F) calibrated by measurements of the flame temperatures at a plurality of predetermined positions of the control elements, and wherein the function (F) is an analytical function of a type T=F(s, x, y), where T refers to an N-dimensional vector which includes the flame temperatures of the individual burners, a M-dimensional vector s includes positions of the control elements, a K-dimensional vector x includes measured values of measured value detectors and control values of autonomous fuel control devices and an L-dimensional vector y includes estimated deviations that influence throughflow characteristics of the control elements; and determining and adjusting the positions of the control elements of the fuel distribution system which are optimum for a predetermined distribution of the flame temperatures of the burners based on the calibrated function (F). |
