1. Intended use
The environmentally friendly boilers ATMOS DC105S and DC150S are intended for heating in
gardening centres, large houses, various workshops, business premises and similar buildings. The
boilers are suitable for outputs ranging between 70 - 150 kW.
The boilers are designed for burning wood pieces only. Any dry wood may be used for heating.
Wood logs and wood splits of 550 - 750 mm maximum length (depending on boiler type) in particular.
Larger diameter logs may be used as well; then the boiler‘s nominal output decreases and the combus-
tion time increases. The boilers are not intended for burning saw dust or small-particle wood waste.
Due to their huge feeding hopper, it saves the user a lot of laborious wood splitting and treating
operations. It saves both - the physical effort and also the time dedicated to these operations.
2. Technical description
The boilers are designed for burning wood based on generator gasification principle utilising two
extraction fans (ventilators), which extracts the flue gas from the boiler The boiler drum is manufac-
tured as a welded structure of 3 - 10 mm thick steel sheets. The boiler consists of a fuel-feeding hopper
which is in the lower section fitted with a heatproof (nozzle) shaped piece with a longitudinal opening
allowing the waste gasses and fumes to escape. The burn-off chamber situated underneath is fitted
with other heatproof (fireclay) shaped pieces. There is a vertical flue-gas duct in the back of the boiler
body which is in the upper section equipped with an ignition valve. A gas outlet pipe for a chimney
connection is situated in the upper part of the flue-gas duct. The boiler‘s front wall is fitted with a
loading door (in its upper section) and an ash-pan door (in the lower section). Lids are placed on both
sides of the ash-pan door. A tube heat exchanger with flue gas brakes are situated behind these lids.
In the front section of the upper hood there is an ignition valve pulling rod. The boilers’ drum is ex-
ternally heat insulated by 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.
Primary air for ideal burning of the boiler enter on the sides of the boiler through a special valves
controlled by actuators. Secondary air is supplied from the front and rear sides of the boiler. The pri-
mary and secondary air is pre-heated to a high temperature.
