PURPOSE:To prevent burners from one-sided burning, by displaying quenching sequence for burners on a display unit in such a manner that an operator can visually monitor the burning status of burners without fail, taking prevention of one- sided burning into account. CONSTITUTION:An input data scanning means 3 senses signals V1 and V2 from an input unit 2 and puts them into a storage unit 5 as an information ''S'' of igniting and quenching status of a burner 1. The means 3 also senses the change in V2 and puts its information into an igniting and quenching sequence deciding means 4 as an information ''I''. The means 4 receives the information ''I'' in regard to the change in the status of contact points from the input data scanning means 3, comparing the status information ''S'' of burners, which is put into the storage unit 5 by the means 3, with the igniting and quenching rules ''P'' and ''R'' for burners which have been stored in the storage unit 5, deciding the igniting sequence for the quenched burners, and the quenching sequence for the ignited burners, making up a table N1 for igniting sequence, and a table N2 for quenching sequence, with each sequence corresponding to each burner, and putting these tables into the storage unit 5. A display means 6 makes up a display information ''C'' from the table N1 for igniting sequence, the table N2 for quenching sequence, and the status information ''S'' of burners, and puts it out to a display unit 7. |
