PROBLEM TO BE SOLVED: To improve safety and stability in combustion.SOLUTION: A combustion control devices (1A, 1B) control operations of N pieces (N is an integer of 2 or greater) of burners (21A-24A, 21B, 24B), and stop the operations of all of N pieces of burners when combustion states of the N pieces of burners satisfy prescribed conditions. The prescribed conditions include a first cutoff condition (1031) for stopping operations of the N pieces of burners at an initial start to ignite desired burners from a state that none of the burners is ignited, and a second cutoff condition (1032) for stopping the operations of the N pieces of burners in a normal operation state after the desired burner are normally ignited at the initial start.SELECTED DRAWING: Figure 2 |
