Chapter 4 Safety Device
4-1 Superheating Prevention for the Boiler Main Body
(1) Burner Operation Suspension at the Low Level
1) 0.5 – 1.5 T/H
A device which controls the feed water pump and burner
automatically for superheating prevention by the electrical
signal from the computer by sensing the water level.
When the water level dropped down to the low water level limit,
the combustion circuit of burner is shut off automatically (when the
water level is not reached to the high water level limit in the initial
operation stage, the blower is not operated and the burner is not ignited).
Once the water level reached up to the high water level
(Water Level Control for Superheating Prevention)
limit, the feed water pump operation is repeated in between the high water level and the medium water level. If the
wire of the lighting bar holder is disconnected, correct water level control is impossible and make a abnormal noise.
The foreign substance on the lighting bar have it be difficult to detect the water level and causes the superheating.
Therefore periodic cleaning is required.
