Intended Use; Technical Specifications - Atmos C15E Instruction Manual

1. Intended use

The environmentally friendly boilers ATMOS DC 15/18/20/22/25/30/32/40/50/70/75 are designed
for heating family houses, cottages, holiday houses and other similar objects. Boilers are suitable for
buildings with heat loss ranging between 15 - 75 kW, depending on type. The boilers are constructed
mainly for burning log food. Any type of dry wood is suitable for heating, especially wooden logs,
splinters up to a maximum length 330,530,730 and 1,000 mm as per the boiler type. It is possible to
use wood of a larger diameter in the form of logs; the nominal output is then decreased and the burn-
ing 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-firewood. MAX.10%. Due to their huge
feeding hoppers, the boilers save the user a lot of laborious wood treating and splitting operations.
They save both - the physical effort and also the time dedicated to these operations.
2. Technical specifications
The boilers are designed for burning wood based on generator gasification principle utilising an ex-
traction ventilator (DC15E excluded), which extracts the waste gas from the boiler or blows the air in
the boiler.
a) Gas extraction ventilator – for boilers DC18S, DC22S, DC25S, DC30SE, DC32S,
b) Pressure ventilator
c) Without ventilator
The boiler drum is manufactured as a welded structure from 3-8 mm thick steel sheets. They are
made of fuel hopper, which is in the lower part equipped with a heatproof shaped piece with longi-
tudinal opening for combustion products and gates. The burn-off chamber is equipped with ceramic
shaped pieces. There is a vertical waste 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 waste 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' drum 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 fitted with a control valve, which is operated by FR 124 draught regulator.
Primary and secondary air is preheated to high temperature. For boilers DC50SE, the valve with the
FR 124 draught regulator is replaced with servo drive with inbuilt spring. This boiler also contains
two special steel plates alongside the gasifying nozzle.
