Abstract

PURPOSE: To start safely and quickly a boiler, installing pressure in the steam shell detector differentiator to calculate pressure increase slope by the signal from the detector, boosting setting timer, and controlling means to control the supply quantity of heat control device.
CONSTITUTION: When pressure slope in the steam shell 7 calculated with a differentiator 13 agrees with output of boosting setting timer 14, controlling means 16 does not output, opening of fuel regulating valve 4 remans as it is. When pressure slope in the steam shell 7 exceeds the output of boosting setting timer 14, output issues from the controlling means 16, fuel supply flow is decreased operating to the direction to shut the fuel regulating valve 4, pressure increase slope in the steam shell 7 is corrected moderately, when pressure increase slope in the steam shell 7 lowers less than the output of boosting setting timer 14, counter output from the controlling means 16 output to opreate the fuel regulating valve 4 the direction of opening, fuel supply flow increases to modify the pressure increase slope severely, and the boiler is boosted along prescribed boosting curve.
