Burner assembly diagram
The burner must be installed according to the burner
manufacturer’s requirements and bearing in mind that the burner:
a. must have thermal output suitable to thermal input
(nominal input) of the steam generator;
b. must be able to overcome the pressure losses of the
generator’s smoke circuit (pressurised combustion);
c. must be fitted with a blast tube, the length of which shall meet
the minimum length specified for each generator (see figure
below and section 2.4 Operating data);
d. In addition, the generator’s flame sight glass must be
connected to the burner’s air inlet.
If the cooling tube is not connected to the
flame sight glass, it could cause the glass
to blacken and break.
