Open damper (p.1) with draught adjuster.
Check the smoek color out of chimney. Smoke should be thin of a
light grey color. If smoke is thick and black it means incomplete
combustion, not enough secondary air. Open secondary air supply
dampers.
As a part of combustion process ash is formed, it blocks the
openings in fire grate, boiler capacity and combuistion intensity
drops. Move the fuel and ash by pressing the pedal of the fire grate
mover. Excess of ash in an ashtray blocks primary air supply, that is
why ash needs removal. Boilers K-2-30 and K-2-40 Bottom doors
have two primary air dampers. Top damper allows air flow even
when ash blocks fire grate openings.
Unless there is a necessity it is not recommended to open fuel
loading doors (p.5 and p.8) during combustion.
Boiler premises have to be well ventilated.
Recommenmded fuel humidity not greater than15-20 %.
Attention!
If the boiler combusts humid wood or saw dust,
condensate will form acids which will shorten the life span of the
boiler several times
5.3. I
nstalling and adjusting the draught adjuster
Draught adjusters manufactured by Swedish ESBE C20/25 with
protection from boiler overheating or without it are used. Adjuster is
turned into a socket, scotch tape is used for sealing, Attach chain to
air supply damper.
When boiler heats up to 70°C, adjust adjusters handle to position
"4" and shorten the chain so that, air supply damper is closed.
Turning adjuster to the correspondent position sets desired
temperature. Position "6" corresponds to 90°C. Temperature
increment between positions is 10°C.
5.4.Boiler cleaning.
To ensure optimum boiler performance slag has to be removed
from the burner and ash has to be cleaned from the internal boiler’s
surfaces.
Burner cleaning periods depend on pellet quality. When pellets
with lots of admixtures are combusted burner should be cleaned
every day.
