Furthermore, the multiple ?ues or heat trans

such a way that the heatais quickly transferred to

Each turbine type engine embodies a plurality
of alternate stators 32 and rotors 33, best shown
in Figure 1, the stators and rotors being equipped
with the conventionalpV-shaped vanes 34 and 35
which de?ect the steam at an angle from ‘one
15 <stator against the vanes of the next adjacent
rotor so that rotation is imparted to the latter in
the conventional manner.

20 eous products of combustion a fan 36, best shown
in Figures 5 and 6, is keyed to each engine shaft
at the intake end of each engine andv is separated from the initial stator of each engine by
partitions 31 and 38,’best shown in Figure 1.
The partition 31 is provided'with a ‘port 39 adja
