1.2 On Product
•
TOBY represents one of the most sophisticated solutions for automatic combustion of wood pellets
to be found on the market.
•
It is completely adapted to burn wood pellet as a primary fuel, achieving maximum efficiency level
up to 94% and a very low exit temperature for flue gases (below 160
◦
C).
•
Ignition, start-up and turning-off are fully automatized. Combustion control is optimized using
algorithms such as ‘modulation’ which automatically decreases pellet dose as the difference between
desired and reached temperature is decreasing.
•
Working principle of this boiler is based on the “sub-pressure” of the heating chamber. The chamber
is completely air-proof so that air flow in the boiler is fully controlled by the exhausting fan mounted
on the back. Boiler regulation completely controls the quantity of the air inside the heating chamber:
optimum combustion comes as a result.
•
Boiler chamber is made by welding 5mm thick steel plates (all surfaces in touch with fire). Other
parts are made of 4mm steel.
•
The efficiency of this boiler is much higher than that of the conventional boilers with natural air
flow. This boiler does not need a long chimney, just an ordinary flue gas outlet. It can be put in
any part of the building, which is easily done thanks to its compact dimensions (pellet storage is
above boiler, overall boiler length 70cm only).
•
Pellets are fed to boiler via internal transporter screw inside the storage tank. From there pellets
are fed over to heating chamber where they fall free to the designated melting area (the ’actual’
embedded burner of the boiler). Storage and melting area are physically divided. There is no chance
for reverse fire to happen.
•
Maintenance and cleaning are reduced to a minimum compared to all solid fuel boilers – only once
a week, if not less than that, with a premium quality pellet and proper use. Please note the handle
on the front side of the boiler. This is designated for occasional cleaning of the heat exchanger of
the boiler (forcing the ash to fall down to te bottom of the boiler).
