How to choose the burner
To check if the burner is suitable for the boiler to which it must be installled, the following parameters are needed:
z
fuel
z
furnace input, in kW or kcal/h (kW = kcal/h / 860);
z
boiler type;
z
combustione head type (reverse flame or three phase)’
z
temperature or pressure of the thermal carrier fluid
z
Comburent air temperature
z
Air duct positioning
z
Pressure in the combustion chamber
z
Elevation (altitude) of burner installation
z
Gas train (only for gas burners)
z
Pumping unit (only for light-oil or heavy-oil burners)
z
Air fan
z
Bilt-in or separated control panel
z
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 mani-
facturer Technical Dpt.
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. Technical features can be summarised in a higher modulation
ratio (fewer start-ups, less consumption, fewer swigings in the generator temperature and pressure values.
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
gas.
Draw a vertical line matching the furnace input value (600kW, in the example), quoted on
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
gas
value, calculated before.
Data requested:
z
furnace input;
z
air temperature
z
altitude
z
generator pressure or temperature
Example:
z
furnace input: 9600kW
z
air temperature: 15°C
z
altitude: 0m
