Abstract (en)
[origin: US2010307387A1] A combustion furnace control apparatus for which an operation control system that ensures the combustion safety of the combustion furnace can be constructed easily. Interlocks pertaining to the safe operation of a combustion furnace are classified as a 1st interlock pertaining to the safe operation of the overall combustion furnace, a 2nd interlock pertaining to the combustion environment of a combustion zone and a 3rd interlock pertaining to the combustion of a burner. Whereby, a common control module judges the state of the 1st interlock and controls the overall operation of the combustion furnace; a combustion zone control module, receiving a control signal from the common control module, operates to judge the state of the 2nd interlock and prepare the combustion environment for the combustion zone; and a burner control module, receiving a control signal from the combustion zone control module, operates to judge the state of the 3rd interlock and control the operation of the burner.
