置。 In a drum water level control device for a boiler, a regulating valve is provided on the inlet side of the drum, and when the water level in the drum is excessive or insufficient, a water level signal is given to control the valve opening of the regulating valve. The signal and the pressure signal are taken out, these signals are calculated, and when the calculated signal is higher than the predetermined set pressure, the drum water level setting is increased, and when the calculated signal is higher than the predetermined set pressure. When it is low, a signal is generated to lower the drum water level setting,
A drum water level control device for a boiler, characterized in that it is provided with a program setting device that controls the water level of the drum by applying any one of the signals to the regulating valve.
