Abstract
A combustion controlling system according to the present invention provides a signal path for transmitting the normal combustion signal SB output from the master device to the transmission line through cascade-connected slave devices. Then, the combustion controlling system determines whether each of the slave devices outputs the normal combustion signal SB to the subsequent device based on whether there is a flame of the corresponding burner, or not, during the combustion of burners, and the master device closes a safety shutoff valve on the condition that an input of a normal combustion signal SBo from a transmission line is stopped.
