Claims

[Scope of utility model registration request]

The annularly formed upper header and lower header are connected by multiple water pipes, the water level control section is connected by a communication pipe, the steam separator is connected by a steam introduction pipe and a return pipe, and the upper header and lower header are connected. In a multi-tube once-through boiler, which is installed separately from the water pipe and equipped with a water level detector and an intermittent blow solenoid valve in the steam/water separator or return pipe, the intermittent blow will be activated when the water level detector detects the water level. An automatic intermittent blowing device for a multi-tubular once-through boiler characterized by opening a solenoid valve for a preset time to perform intermittent blowing.
