11.0 Heating section with bypass
channels
In parallel with the heating section enclosure
(see fig. 4, table 1) a bypass channel can be
made. This might be needed to reduce the
pressure drop over the heating section
In case of using a by-pass, the recommended
by-pass dimensions are shown in figures 16 to
19. The table shows dimension ‘A’ of by-pass
versus total air flow (expressed in m³/s). In
this case the air flow anymore though the
heating section enclosure will not be equal to
the total air flow, as part of the air flow will be
through the bypass channel.
The recommended by-pass dimensions are
such that when applying them, the resulting
air flow over the heating section will be equal
to the minimal air duty, as shown in table 2. In
fact, the recommended dimensions are
maximal allowable dimensions for the by-pass.
This case is opposed to not having a by-pass,
in which case total airflow will be equal to air
flow over heating section.
To use the pressure drop curves without by-
pass, this can simply be done by putting the
total air flow on the figure, and extract the
pressure drop directly from it.
In case the recommended by-pass dimensions
are respected, the pressure drop can be
extracted from the figures by using the
minimal air flow, as showed in table 2, and
always corresponding the the left edge of the
x-axis in the pressure drop figures.
This means that in case the by-pass
dimensions are between 0 (or none) and
recommended dimensions, the air flow over
the heating section (which has to be used in
the pressure drop figures) will be somewhere
between the total air flow and the minimal
allowed air flow.
