STATIONARY ENGINEER ELECTRIC FINAL
PAPER 2026 COMPLETE QUESTIONS AND
ANSWERS
◉The sediment chamber is the lowest part of the water column.
Answer:
◉Interlocks on boiler controls are designed to open on failure.
Answer:
◉The modulating control system controls low fire and high fire.
Answer:
◉The automatic combustion control system tries to control the
proper steam pressure.. Answer:
◉On/off control systems has only 2 conditions, on or off. Answer:
◉Microprocessor based burner management control system is
responsible for combustion safety. Answer:
,◉The pressure controls control cut in/cut out. Should be mounted
to the highest part of the steam side of the boiler. Protected by
siphon. Needs to be mounted in the vertical orientation.. Answer:
◉The cut in of the pressure control is the main minus the
differential. The main = the cutout pressure.. Answer:
◉-Boiler startup procedure: Pre purge the boiler for 30 seconds,
light the pilot, prove the pilot for 10 seconds, light the main burner,
prove the main burner, secure pilot after main flame has been
established. Reach cutout point (Main)-secure fuel, and post purge.
The controls have 4 seconds to secure the fuel if we lose the flame..
Answer:
◉Purge is done in high fire position. The boiler goes to low fire
position to light off. Answer:
◉The microprocessor control system ensures the boiler is in low
fire before lighting. Answer:
◉Ultraviolet flame scanner is popular method for proving flame.
Answer:
◉The positioning control system and metering control system
require clean, dry air. Answer:
, ◉Hunting is rapid opening and closing of the controls. Answer:
◉Metering control systems give a more accurate means of
controlling steam pressure (variations) than positioning controls.
They are more accurate to fluctuating steam pressure.. Answer:
◉Gate valves are used to connect pressure gauge to siphon because
they offer no restriction to flow. Answer:
◉Opacity control is used to monitor boiler emissions. Answer:
◉A rotometer is a variable area flow meter used to measure flow
usually in GPM's. Answer:
◉Phosphates are used to treat a boiler because they turn calcium
and magnesium into a non-adhering sludge that can be blown down
easily.. Answer:
◉Oxygen pitting is caused by air in the system. The deaerator uses
high temperature to push air from the feedwater. Sodium sulfite eats
the rest of the oxygen.. Answer:
