2. PRODUCT DESCRIPTION
PyroBurnLambdaboilersaredesignedto
burnsolidfuel–woodorwoodbriquees
class B on the principle of wood gas
generaon using a fan. The body of
the boiler is manufactured as welded
sheet-steel structure. It comprises a
loading chamber which in its lower part
is equipped with ceramic nozzle with
longitudinal slot through which passes
the wood gas produced. Below it is the
combuson chamber where the wood
gas burns, lined with ceramic refractory
pieces.Onthefront,intheupperpartof
the boiler is located the upper door for
loading the upper chamber with wood,
and in the lower part is the combuson
chamberdoor.Opendoorsensordetects
when boiler door is open and acvates
fumeextractorfanonfullspeed(100%).
Fume extractor fan draws smoke from
the chamber to the chimney via back-
sideupperchamberopening.Opendoor
sensorfunconistopreventboilerroom
from fume polluon when reloading.
The boiler body is heat-insulated on the
outsidewithmineralwoolinsertedunder
the housing. Smart MCU controller is
build-upinboilerupperpart.
• Design. Boiler body is made of high-
qualityboilersteelsheetswiththickness
of 6 mm for the combuson chamber
and4mmforthewaterjacket.Thebuilt-
in refractory ceramic pieces help ensure
theuniformtransferoftheheatproduced
tothewaterjacketandprotectthesteel
walls from the high temperatures (up to
1200°С).
• Pyrolyc combuson. Wood in the
loading chamber burns (above 580°С)
and releases wood gas rich in carbon
compounds. When combined with the
primary air it forms a burnable mixture
and is then routed to the nozzle in the
combuson chamber. In the nozzle the
mixture is enriched with secondary air
and is self-ignited in order to reach the
combuson chamber at 1200°С. Before
leaving the boiler body, ue gases pass
throughuepipeswheretheylosetheir
heat and cool down to 150°С. Pyrolyc
combusonhelpsachieveecientwood
burningwithminimumproduconofash.
• Eecve. Thanks to the pyrolyc
principle of wood burning, the boiler
achieves eciency of more than 92%.
The water jacket envelops the enrety
of the combuson chamber in order to
ulize maximum amount of the heat
produced.Ontheoutside,theboilerbody
isinsulatedbymeans of50mmlayerof
mineralwoolthermalinsulaon.
• Intelligent microprocessor control unit
ThePyroBurnLambdaboilerisequipped
with a hi-tech reliable controller
capable of managing complex heang
installaons. The controller manages
the combuson process via permanent
monitoring of oxygen levels in exhaust
gases, their temperature as well as
the boiler temperature. Depending on
those values the controller adjusts air
intake into the primary and secondary
combuson chamber. The control unit
is capable of managing various heang
circuitswhereasithas3typesofheang
installaonsembeddedinitslogic.Thanks
to the integrated lambda sensor the
combusonprocessisopmizedtosuch
an extent that boiler eciency exceeds
92%,andexhaustgasemissionsconform
tostrictestEUstandards.
The microprocessor control is able to
controloneheangcircuitandoneDHW
