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).
•
Emission levels of this boiler fulfill the most rigorous norms of European countries. TOBY 30 is
officially tested as a Class 5 boiler according to EN 303-5 at KiWa Institute in Treviso Italy and is
eligible for subventions and grants available in most EU countries.
•
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.
•
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 a
safety thermostat to prevent back-fire. There is also a pressure sensor inside the heating chamber
