figure 8.7, consists of six liners, a fuel nozzle cap, a fuel nozzle cup adapter, and male or female flame
tubes.
Figure 8.7. Combustion Chamber.
The combustion chamber outlet duct,
shown in figure 8.8, acts as a transition area to
combine the gas flow from the eight combustion
chambers and introduce it into the first stage
nozzle vanes.
The fuel manifold consists of a
secondary manifold within the primary manifold.
Eight duplex fuel nozzles, one for each
combustion chamber, are placed around the fuel
manifold. Each nozzle has a primary orifice and
a secondary orifice. Fuel sprays from the primary
orifice during low pressure and from both orifices
at high pressure. Fuel strainers in the primary
and
