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:
furnace input, in kW or kcal/h (kW = kcal/h / 860);
backpressure (data are available on the boiler’s ID plate or in the user’s manual).
Example:
Furnace input: 600kW
Backpressure: 4mbar
In the “Performance curve” diagram (Fig. 2), draw a vertical line matching the furnace input value and an horizontal line matching the
backpressure value. The burner is suitable if the intersection point A is inside the performance curve.
Fig. 2
Data are referred to standard conditions: atmospheric pressure at 1013mbar, ambient temperature at 15°C.
Burner model identification
Burners are identified by burner type and model. Burner model identification is described as follows.
