1. a boiler controlling device, is characterized in that, comprising:

  • Water-level gauge, the water level of this water-level gauge to the boiler water be stored in boiler-steam dome measures;

    Feed water valve, the flow of this feed water valve to the boiler water being supplied to described boiler-steam dome adjusts;

    Blowout valve, the flow of this blowout valve to the boiler water blown out from described boiler-steam dome adjusts;

    First-class gauge, the flow of this first-class gauge to the boiler water being supplied to described boiler-steam dome measures;

    Second gauge, the flow of this second gauge to the steam of releasing from described boiler-steam dome measures;

    3rd flowmeter, the flow of the 3rd flowmeter to the boiler water blown out from described boiler-steam dome measures;

    Conductivity meter, this conductivity meter measures the boiler electrical conductivity of water be stored in described boiler-steam dome;

    First control part, this first control part is based on the measurement result of described water-level gauge and the measurement result of described first-class gauge controls described feed water valve, make described water level reach constant;

    AndSecond control part, this second control part calculates the described electrical conductivity after the stipulated time based on the measurement result of the measurement result of described conductivity meter, the measurement result of described second gauge and described 3rd flowmeter, and control described blowout valve according to result of calculation, make described electrical conductivity in setting range.
