Firing rates

The MAXIMUM OUTPUT is chosen from within the continuous
diagram area (Fig. 2).
The MINIMUM OUTPUT must not be lower than the minimum
limit of the diagram:
GI/EMME 1400 = 407 kW
GI/EMME 2000 = 581 kW
GI/EMME 3000 = 872 kW
GI/EMME 4500 = 1163 kW

Test boiler

The burner/boiler combination does not pose any problems if the
boiler is EC approved and its combustion chamber dimensions
are similar to those indicated in the diagram (Fig. 3).
If the burner must be combined with a boiler that has not been EC
approved and/or its combustion chamber dimensions are clearly
smaller than those indicated in the diagram, consult the
manufacturer.
The firing rates were obtained in special test boilers, according to
EN 676 standard.

The firing rate value (Fig. 2) 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

In Fig. 3 you can see the diameter and length of the test
combustion chamber.
Example:
Output 7000 kW - diameter 120 cm - length 6 m
MODULATING RATIO
The modulating ratio, obtained in test boilers, according to
standard (EN 676 for gas, EN 267 for light oil), is of 4:1 for light
oil and 7:1 for gas.
