Checking the proper gas train size
BURNER SPECIFICATIONS
Burner model identification
Burners are identified by burner type and model. Burner model identification is described as follows.
Fuel
The burner technical specifications, described in this manual, refer to natural gas (calorific net
value Hi = 9.45 kWh/Stm
3
, density
ρ
= 0.717 Kg/Stm
3
). For different fuel such as LPG, town gas
and biogas, multiply the values of flow and pressure by th corrective factors shown in the table
below.
For example, to obtain the flow and pressure values for the biogas:
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
pgas.
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
interception 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
pgas
value, calcula-
ted before.

ATTENTION! The combustion head type and the settings depend on the fuel. The burner must be used only for its
intended purpose specified in the burner data plate .
ATTENTION! The corrective factors in the above table depend on the gas composition, so on the calorifc value and
the density of the gas. The above value can be taken only as reference.
