Example
• Burner TBML 510
• Pressure measured on port G: Ptc= 64,9 mbar
• Back pressure measured in the furnace: Pcc = 22,9 mbar
• Head pressure value without the back pressure in the furnace: P
= 64,9-22,9 = 42 mbar
From the diagram, in correspondence of pressure P = 31 mbar, a com -
busted thermal flow rate of about 3600 kW can be inferred.
POWER AT START-UP
The standard EN 676 prescribes that for burners with maximum output
above 120 kW the ignition must occur at a reduced power Pstart
than the maximum power of operation Pmax at which the burner is
calibrated.
Pstart depends on the safety time of the burner equipment; in par -
ticular:
ts = 2s → Pstart ≤ 0.5 x Pmax .
ts = 3s → Pstart ≤ 0.333 x Pmax .
Example if the maximum regulation power of the burner Pmax is
equal to 900 kW, it must be:
Pstart ≤ 450 kW where ts = 2s
Pstart ≤ 300 kW where ts = 3s
Check power at ignition
• Disconnect the flame sensor wire (in this case the burner turns on
and goes into lock-out after the safety time ts).
• Perform 10 consecutive ignitions and following block.
• Measure at the meter the amount of gas burned Qstart [m³]
and check that Qstart ≤ Pmax /360 ( in m³/h)
Example
Pmax = 90 m³/h (about 900 kW with natural gas)
After 10 ignitions with the related lock out, the gas consumption read
on the meter must be:
Qstart ≤ 90/360 = 0.25 [m³]
If this does not occur, reduce the flow of gas to the ignition through the
brake of the valve.
