5. CHOOSING THE RIGHT BURNER
In order to make to right choice of burner - both technically and practically - you need to take
under consideration certain basic parameters:
1.
The burner is designed to burn wood pellets ONLY. The use of any other type of pellet
such as agro-pellets (pellet made of agricultural by-products) without the approval of the
manufacturer is explicitly prohibited.
2.
Make sure that your boiler is designed to burn pellets. The manufacturer of the boiler
will indicate the appropriate type of fuel and will provide relevant information for proper
combustion including the following:
Output power for the particular fuel. This should be equal to or less than the
maximum rated power of the burner as indicated on the name plate of the burner.
Minimum chimney draft.
Regulation of the burner’s damper.
Exhaust gas temperature.
3.
Additionally, please note that:
The minimum capacity of the combustion chamber should be 0,06 m
3
in respect of
models bio 2 and 1 and 0,12 m
3
in respect of model bio 3 in order to achieve the
maximum power of the burners.
For the unhindered opening of the boiler door both the door and the burning
chamber of the boiler should have minimum width as follows:
o
Thirty (30) cm in respect of model bio 2
o
Forty (40) cm in respect of model bio 3
The minimum length of the burning chamber should be:
o
Forty (40) cm in respect of model bio 2
o
Fifty two (52) cm in respect of model bio 3
The length of the flame should be at least five (5) cm below the above mentioned
values.
The space in front of the boiler should be free in an arc 90° towards the same
direction to which the door opens and at a distance of at least a hundred (100) cm to
ensure unhindered door opening when necessary.
The burner should be installed ONLY in horizontal position.
POINTS TO REMEMBER
The technician responsible for the installation and the first fire up of your burner is
obliged to provide you with a “Combustion Certificate” which includes the following:
The type of the burner
The type of the boiler
The exhaust gas temperature
The content in CO and CO2.
