Environmental instructions
Packing
Packing is made of 100 % waste materials.
Dispose of packing in accordance with local
waste disposal requirements.
Removal from Service
The boiler should be delivered to a waste dis-
posal point for electric and electronic compo-
nents.
Operating Principle
ECONATURE-40 is a solid-fuel water-
heating boiler operating on a rotating combus-
tion principle designed for heating systems in
private houses. The rotating combustion tech-
nique used in ECONATURE-40 is even 30 %
more energy saving than the conservative
upper burning technique.
Firewood Burning Phases
D
RYING
: Dehumidification of firewood.
P
YROLYTIC DECOMPOSITION
: Wood starts to
break apart and change to coal and gas. Pyro-
lytic decomposition begins at a temperature
above 100 ºC; when the temperature exceeds
280ºC the resulting reaction causes heat re-
lease. Secondary combustion (the reaction
between pyrolytic gases and oxygen) begins
at a temperature over 600 ºC.
R
EMAINING COAL BURNING
: Remaining coal
burns after pyrolytic gases are removed.
After firewood starts to burn the temperature
must rise quickly since secondary burning
will not be efficient until the combustion tem-
perature is high enough. Efficient and clean
combustion implies full control over the burn-
ing process throughout its phases. The rotat-
ing combustion technique uses secondary
firewood burning efficiently where flue gases
provide additional burning in a separate firing
throat and obtain the hottest and cleanest
flame possible simultaneously reducing ha-
zardous flue gas emissions notably. During
the secondary burning process, the flame
temperature exceeds 1000 ºC making com-
bustion efficient and clean.
