Smoking
chimney draught not sufficient
check chimney’s permeability and
its parameters (see tab. height
and section to boiler’s power,
check if chimney end is not lower
than roof ridge
gases channels dirty
clean up boiler through washout
holes
sealing rope indoor and
washout openings worn
replace a rope (to be replaced
regularly)
orifices leading the air to retort
blocked
clean the retort, make orifices
permeable
improper assembly of boiler
and chimney connection
check accurateness
very low atmospheric pressure
improper position of smoke
throttle to current chimney
draught (it might occur smoke
from blowing fan or the lover

rise
installation valves closed
open the valves
pressure vessel frozen
heat the pressure vessel
Water licking
out of
boiler
so called boiler’s sweating",
this is natural process caused
by temperature difference in
boiler
during boiler’s start-up and after
each standby "heat the boiler" e.g.
burn it up to 70°C and keep that
temperature for several hours
Inappropriate
flame picture

red, smoking fire indicating to
low air supply
provide more air
Pale, white fire indicates to
high air supply
provide less air
very shallow fire in retort
indicating, that percentage of

too
low
comparing to the amount of air
delivered
provide more coal or less air
reducing blow-in power
discarding

completely burned off pieces of
coal
reduce the set of fuel supply by 5
– 10% or increase blow in power.
Wait 20-30 minutes until such
