Technical description of the burner
4.8 Firing rates
The burners RLS 28 - 50 can work in two ways: one-stage or two-
stage.
The
MAXIMUM OUTPUT is chosen within area A (and B for RLS
50)(Fig. 2). To use also area B (RLS 50), the combustion head
has to be pre-calibrated as shown on page 18.
The
MINIMUM OUTPUT must not be lower than the minimum
limit of the diagram:
RLS 28 = 100 kW = 8.5 kg/h
RLS 50 = 145 KW = 12.3 kg/h
ATTENTION
The firing rate value (Fig. 2) has been obtained
considering an ambient temperature of 20 °C, an
atmospheric pressure of 1013 mbar (approx. 0 m
a.s.l.), and with the combustion head adjusted as
shown on page 20.
