Page Operation and maintenance manual for the KSM series boilers with feeders. The producer reserves the right to introduce technical modifications.
2.5. Fuel
Fuel used for combustion in the KSM boiler should have suf-
fi cient calori fi c value > 28 MJ/kg, be dry (moisture content
< 11%), have a size recommended by the producer 5-25 mm,
have correct ash content (maximum 2-7%) and have > 15%
of the volatile content. Use of moist or too large fuel can lead to
locking in the feeder and serious failure of the boiler. The unfa-
vourable chemical composition of the fuel can result in sintering
and formation of large amounts of dust and soot and increased
fuel consumption. Boiler burn time depends on many factors:
the calori
fi c value of fuel, thermal insulation building, equip-
ment receiving the heat (heaters, boiler, fl oor heating). Burn
time period is longer by several hours during boiler operation
with lower thermal power..
PRIMARY FUEL
its use ensures that the boiler will achieve the declared heating power and e ffi ciency
KSM
hard coal
(eco-pea coal, class 28/50/06 with grain size 5-25 mm)
2.6. Equipment
Prior to the boiler setting you should check the presence of addi-
tional tools and operation of the instrumentation. The complete
set should include: automatic feeder, fuel container, electronic controller, fan, brush, hook, ash shovel,
drain cock, fuel swirlers (one piece for each smoke tube).
3. BEFORE START - UP
3.1. Boiler room
• It should be a separate room with height not lower than
2.2 m in the newly constructed building (in the already ex-
isting buildings the allowable height equals to 1.9 m).
• It should have arti fi cial lighting installed and have natural
lighting as far as practicable.
• It should have gravity ventilation in good working order,
including:
1. air-supply duct in the external wall with cross-section
not lower than 50% of chimney cross-sectional area on
height maximum 1 m over the
fl ooring or not lower than
200 cm
2
for boilers with power up to 25 kW or 400 cm
2
for boilers over 25 kW,
2. separate air-exhaust duct on the internal wall with
cross-section not lower than 140 × 140 mm with an out-
let located under the boiler-room roof near the chimney.
NOTE! It is forbidden to use mechanical exhaust ventilation
in the room where the boiler was installe.
• Floor gully and fl oor with 1% slope towards the outlet
should be planned in the central part of the room.
• Flooring and walls in the whole room should be made of
non-combustible materials.
• The doors to the boiler room should open outwards.
