Technical description of the burner
4.8 Firing rates
The firing rates have been defined in compliance with the
provisions of the
EN 676
standard. The burner can be used for
operation with the combustion chamber featuring negative
pressure (up to - 2 mbar) according to the terms of approval
provided for in
EN 746-2
for the whole unit complete with
equipment.
4.9 Test boiler
The firing rate has been defined according to EN 676 standard.
4.9.1 Commercial boilers
The burner-boiler matching is assured if the boiler conforms to
EN 303 and the combustion chamber dimensions are similar to
those shown in the diagram EN 676.
For applications where the boiler does not conform to EN 303, or
where the combustion chamber is much smaller than the
dimensions given in EN 676, please consult the manufacturers.
ATTENTION
The firing rate value (Fig. 3) has been obtained
considering an ambient temperature of 20 °C, an
atmospheric pressure of 1013 mbar (approx. 0 m
a.s.l.), and with the combustion head adjusted as
shown on page 17.
