PURPOSE:To be able to guide effective ignition and fire-extinction for burners by determining fuel flow quantity and the number of used burners corresponding to a target load on the basis of memory for the relation between fuel pressure and flow quantity in accordance with the number of used burners. CONSTITUTION:A guide detector 1 memorizes a burner characteristic curve and is able to recognize the present status from conditions of ignition and fire-extinction, flow quantity,and pressure fed to the detector. When a target value of flow quantity and a rate of change are fed, a memorized burner characteristic curve is referred and the the number of used burners is determined and the order of the burners to be ignited and extinguished is determined by a built-in order setting function for ignition and fire-extinction and the scheduled time is indicated by a guide indicator 2. |
