F. COMBUSTION FLIGHTING
Flight design in the combustion zone is very important. Correct flighting can minimize pollutant
emissions, and provide heat shielding to keep the drum surface temperature down. To obtain
complete combustion, the combustion zone must be sized to provide enough combustion volume
for the flame to burn, and it should also be clear of veiling material that can quench the flame,
resulting in poor combustion efficiency.
Combustion flights provide protection for the drum by shielding it from direct flame
Construction of the combustion flights should be such that no material is allowed to fall through
the flame. Combustion flights should also have a means of dissipating heat to prevent their
destruction by the flame. This is typically done by plowing material over the fights and keeping
the flights as low as possible to the drum. Consult Eclipse for details on flight design and
combustion zone requirements.
Flights are available from Eclipse to optimize performance of the MegaStar™ on a rotary dryer;
for detailed installation instructions of Eclipse weld-in type flights, see Y7100 in the Appendix. For
additional information on application issues for a MegaStar™ on a rotary dryer, see Hauck
Application Sheet GJ75.
G. BURNER MOUNTING
For MegaStar™ burners with an extended burner nose length, the nose must be
supported to avoid undue strain on the burner housing. Consult dryer manufacturer
for extended burner nose support recommendations.
1. The burner should be mounted on the drum centerline at the same pitch as the drum. Install a
structure to support the burner. Refer to dimensional drawings in the Section D. The support
structure must be able to support the weight of the burner (see Table 3). If the optional primary
air turbo blower (TBA) is to be mounted on the same structure as the burner, allow for the
additional weight. Consult Eclipse for recommended burner mounting options. If applicable,
choose a suitable location for the optional remote mounted fuel rack and primary air TBA
blower. The fuel rack should be firmly attached to the base structure or concrete pad. The
fuel rack is supplied with mounting holes in the base angle iron. Consult Eclipse for the remote
mounted fuel rack dimensional drawing HKY6967 if applicable. Consult TBA blower
instruction sheet (TBA-9) for proper mounting instructions for the primary air TBA blower.
2. The burner is supplied with lifting eyes to facilitate lifting the burner into place. Do not use
the lifting eye on the main blower motor for lifting the entire burner unit. The optional
TBA blower is also supplied with lifting eyes on the blower frame. Do not use the motor lifting
eye to lift the entire blower unit.
