Technical description of the burner
4.7
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. 2).
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 manufac-
turer.
The firing rates were obtained in special test boilers, according to
EN 676 regulations.
In Fig. 2 you can see the diameter and length of the test combus-
tion chamber.
Example:
Output 3000 kW - diameter 100 cm - length 4 m.

Maximum dimensions
The maximum dimensions of the burner are shown in Fig. 3.
Bear in mind that inspection of the combustion head requires the
burner to be opened and the rear part turned on the hinge.
The maximum dimensions of the open burner are indicated by
the L and R positions.
The l position is reference for the refractory thickness of the boiler
door.
