How to interpret the burner's "Performance curve"

To check if the burner is suitable for the boiler to which it must be installled, the following parameters are needed:
fuel
furnace input, in kW or kcal/h (kW = kcal/h / 860);
boiler type;
combustione head type (reverse flame or three phase)'
temperature or pressure of the thermal carrier fluid
Comburent air temperature
Air duct positioning
Pressure in the combustion chamber
Elevation (altitude) of burner installation
Gas train (only for gas burners)
Pumping unit (only for light-oil or heavy-oil burners)
Air fan
Bilt-in or separated control panel
backpressure (data are available on the boiler's ID plate or in the user's manual).
Burners provided with built-in control panel are designed for IP40 index of protection. For other values of IP, please contact the CIB
UNIGAS Technical Dpt.

Burner performance range
See the diagram in Fig. 2, as to find the burners that better suite the power range requested in the exmple (9600kW). Once the models
are founded out, the choice regards technical and economical features.
Checking the proper gas train size
To check the proper gas train size, it is necessary to the available gas pressure value upstream the burner's gas valve. Then subtract
the backpressure. The result is called p
the x-axis, as far as intercepitng the network pressure curve, according to the installed gas train (DN65, in the example). From the inter-
ception point, draw an horizontal line as far as matching, on the y-axis, the value of pressure necessary to get the requested furnace
input. This value must be lower or equal to the p
