Alternate Heating COAL GUN S130, Инструкция по установке и эксплуатации

Страница: 52 / 66

Problem Possible Cause Solution
1.Boiler overheating
a) Sight hole cover flap not releasing
when fan stops
b) Excessive chimney draft
c)
Aquastat set too high or
malfunctioning
a) Check spring for proper tension
b) Install barometric damper in flue
c)
Reduce aquastat setting or replace
aquastat
2. Pressure relief valve vents
a) Expansion tank too small or “water
logged”
b) High limit aquastat not functioning
a) Add expansion tank capacity
necessary for total volume of water
in system or replace water logged
tank
b) Check wiring and replace aquastat
if malfunctioning
3. Coal pot not full of coal
a) Hopper empty or obstruction in
coal hopper
b) Excessive fines, wet coal
a) Check hopper
b) Use dry coal and watch fines
4. Coal burns up inlet tube
a) Grate switch turned off
b) Grate not removing spent ash
c)
Fused coal (clinkers) in coal pot
d) High demand coupled with low
performance
a) Turn on Grate Switch
b) Check for problem in grate motor
circuit or mechanical linkage
c) Remove clinkers (fused coal ash)
d) Check problem item numbers 7, 9,
5. Fire goes out
a) Insufficient demand to maintain fire
b) Large clinkers
a) Increase heat load
b) See paragraph at end of
troubleshooting guide
6. Excessive fly ash in chimney
a) Cyclone funnel plugged
b) Flue pipe between boiler and
chimney too long.
a) Check cyclone funnel and remove
restriction.
b) Reduce length of pipe run
7. Fly ash build-up on swirl tube
a) Condensation causing fly ash to
stick to heat exchange surfaces.
a) Raise return water temperature,
check problem item 9
8. Excessive sulfur odor in boiler room
a) Coal quality low
b) Chimney draft problem:
c)
Down draft
d) Restriction in Chimney
e) Cyclone funnel on Coal Gun has
deteriorated
a) Find better quality coal
b) Inspect chimney
c)
Check chimney design & improve
d) Check & clean chimney
e) Replace cyclone funnel
9. Poor boiler performance
a) Inadequate air for combustion
b) Obstruction to air flow inside boiler
or venting system
c) Excessive ash in coal pot
a) Supply adequate air supply to
boiler room
b) Inspect and clean swirl chamber.
Remove and clean cyclone insert,
check for chimney obstruction
c) Adjust ash removal controls.
Setting Thermal Ash Monitoring
Control higher will lower position of
fire and reduce amount of ash in
coal pot.
10. Coal gas ignitions (evidenced by an
audible bang)
a) Poor draft
b) Too much raw coal on top of coal
pot
a) Assure at least -.04” of WC with a
manometer. Increase flue height if
necessary, or use an auxiliary
power vent, make sure there are
no obstructions in chimney or any
part of venting system
b) Raise position of the fire and shrink
zone occupied by raw coal – This
is accomplished by setting a lower
temperature on the Thermal Ash
Monitoring Control. If this setting is
already at 110º F or lower, consider
adjusting grate timers.
