Claims

[Scope of utility model registration request]

In a multi-tubular once-through boiler 1 in which upper and lower headers are connected by a number of wooden tubes, a water level control tube 2 is installed outside the boiler body and separate from the wooden tubes, and the set water level of a first water level detector is set in the water level control tube 2. The first and second water level detectors 5 and 6 are provided so that the set water level 7 of the third water level detector is higher than the set water level 4 of the second water level detector. Set the third water level detector 8 so that it is higher than the set water level 3 of the detector.
, the first water level detector 5, the second water level detector 6, the third water level detector 8, the water supply pump 9 and the burner 10 attached to the boiler are connected to the controller 12 by a signal line 11,
When the water level of the boiler 1 becomes equal to or lower than the set water level 3 of the first water level detector, the controller 12 receives the signal and operates the water supply pump 9 after the water supply set time t1□, and also operates the water supply pump 9 to stop the burner. After time t2, the burner 10 is stopped, and when the water level of the boiler reaches the set water level 3 of the first water level detector, the water supply pump 9 is stopped immediately or after a set time t2 for stopping the water supply pump upon receiving the signal; Well, burner 10 starts combustion immediately, and the water level of the boiler reaches the second level.
If the water level falls below the water level setting of 4 on the water level detector, the signal is received and the burner combustion is stopped immediately.
The water supply pump 9 is operated regardless of the water supply pump stop signal indicating that the water level has reached the set water level of the water level detector.
The multi-tube type is characterized in that it is configured to receive a signal when the water reaches the set water level 7 of the third water level detector and stop the water supply after the set time t3 for starting.
