Control and/or regulation of a combustion apparatus

A facility for control of a combustion apparatus, the facility comprising:

• a memory storing a limit value and a correction factor;
• a communication connection to a first sensor and a first actuator;
• and
• a processor configured to:
• receive a first input signal from the first sensor;
• use the first input signal to form a first measured value specifying a fuel air ratio, an air ratio, and/or an oxygen content;
• load the limit value from the memory and compare the first measured value with the limit value;
• if the first measured value is less than the limit value or is greater than the limit value, either to load the correction factor from the memory and determine a correction value computationally as a function of the limit value and as a function of the correction factor and the first measured value, or to load the stored correction value from the memory;
• and
• to create a first output signal as a function of the determined or stored correction value and to send the first output signal to the first actuator;
• wherein the factor is greater than one;
• and
• the limit value is a lower limit value and the processor is programmed, if the first measured value is less than the at least one lower limit value, to determine the correction value computationally through augmentation of the measured value or through augmentation of the lower limit value in accordance with the factor;
• or
• the limit value is an upper limit value and the processor is programmed to, if the first measured value is greater than the at least one upper limit value, to determine the correction value computationally by division of the first measured value or of the at least one upper limit value by the at least one factor.
