Pilot - Gas Train Connection; Ignition Pilot Burner - Riello RLS 1600/E C11 Modulating Operation

To calculate the required gas pressure at test point 1)(Fig. 28),
set the maximum modulating output required from the burner op-
eration:
- find the nearest output value in Tab. H for the burner in ques-
tion.
- read, on the right (column 1), the pressure at the test point
1)(Fig. 28).
- Add this value to the estimated pressure in combustion
chamber.
Example RLS 1600/E C11 with natural gas G20:
Operation at maximum modulating output
Gas pressure at an output of 12400 kW
Pressure in combustion chamber
pressure required at test point 1)(Fig. 28).

5.14.5 Pilot - gas train connection

The burner is fitted with a dedicated gas train that is fixed to the
pipe coupling.
 It should be connected to the main train downstream the fil-
ter or the pressure adjuster (depending on configuration).
Supply pressure 68 ÷ 500 mbar.
WARNING

5.14.6 Ignition pilot burner

For proper operation, adjust gas pressure (measured at pressure
test point 1)(Fig. 29) as follows:
Model Gas
RLS 1600/E C11 G20
RLS 2000/E C11 G20
Check pilot flame stability before starting up the
main burner.
WARNING
In the case of ignition problems check:
 correct positioning of the ignition electrode;
 the gas pressure, according to indications.
