Abstract: A steam using facility in which a generated condensate amount changes in association with a change in an environmental state value, based on a correlation between the environmental state value and the generated condensate amount. An environmental state value when the generated condensate amount becomes a set alarm amount is set as an alarm state value. An alarm is issued when an actual environmental state value by a measuring instrument changes in an increasing direction of the generated condensate amount to reach the set alarm state value.
