1. Intended use
The environmentally friendly boilers ATMOS are designed for heating family houses, cottages,
holiday houses and other similar buildings. Boilers are suitable for buildings with heat loss ranging
between 19, 25, 29.8, 40 and 49 kW, depending on type. The boilers are constructed mainly for bur-
ning logs. Any type of dry wood is suitable for heating, especially wooden logs up to a maximum
length 330 - 530 mm as per the boiler type. If you use logs of a larger diameter the nominal output is
then decreased and the burning period prolonged. The boiler is not intended for burning saw dust or
small-particle wood waste. These can be burnt in small quantities only, together with log-rewood.
MAX. 10 %. Due to their huge feeding hoppers, the boilers save the user a lot of laborious wood wood
preparation and splitting operations. They save both - the physical effort and also the time dedicated
to these operations.
2. Technical specications
The boilers are designed for burning wood based on generator gasication principle utilising an
exhaust fan, which suck out the ue gas from the boiler.
The boiler body is manufactured as a welded structure from 3 - 6 mm thick steel sheets. Consist
of the fuel hopper which at the lower end of this hopper comprises a heatproof shaped piece (nozzle)
with longitudinal opening (slot) for passing of combustion products and gases and heat proof shaped
piece at the sides. The burn out (bottom) chamber is equipped with ceramic shaped pieces (spherical
space). There is a vertical ue gas duct at the rear of the boiler body which is in its upper section
equipped with an ignition valve. The upper part of the ue gas duct is equipped with gas outlet pipe
for connecting to chimney. The front wall is in the upper part equipped with stoking door and with
ashtray door in the lower part. In the front section of the upper hood there is an ignition valve pull rod.
The boilers’ body is externally heat insulated with mineral wool placed beneath the sheet metal covers
of the boilers’ external housing.
A control panel for electromechanical regulation is situated in the upper part of the boiler. In the
rear section of the boilers, there is a primary and secondary air feeding duct tted with a control val-
ve, which is operated by FR 124 draught regulator. Primary and secondary air is preheated to high
temperature.
Boiler construction has following advantages
The combustion process proceeds to the function generator gasication at high temperatures. The
boilers called GD are provide with the ceramic re chamber and with the primary air inlets on the
sides.
EXHAUST FAN = COMFORT OPERATION
The boilers pre-heat the primary and secondary air to a high temperature which results in warm
and stable ame of stable burning quality.
Large fuel hopper allows burning of the log pieces with the maximum length 330 - 530 mm, de-
pending on the boiler type. Large pieces of waste wood can also be burned.
All boilers are equipped with cooling loop for overheating protection.
