A turbine- generator device for use in electricity generation using heat
Resumen
from industrial processes, renewable energy sources and other
sources. The generator may be cooled by introducing into the gap
between the rotor and stator liquid that is vaporized or atomized prior
to introduction, which liquid is condensed from gases exhausted from
the turbine. The turbine has a universal design and so may be
relatively easily modified for use in connection with generators having
a rated power output in the range of 50KW to 5MW. Such
modifications are achieved, in part, through use of a modular turbine
cartridge built up of discrete rotor and stator plates sized for the
desired application with turbine brush seals chosen to accommodate
radial rotor movements from the supported generator.
The cartridge may be installed and removed from the turbine
relatively easily for maintenance or rebuilding. The rotor housing is
designed to be relatively easily machined to dimensions that meet
desired operating parameters.

TOWERLANE LTD¿[GB]
Solicitantes
An Archimedes screw device for power generation or material
Resumen
handling has a number of helical pipes supported around a central
support structure. The helical pipes may be formed from pipe portions
that are joined together and wound around the central cylinder.
Attached to the upper end of each helical pipe are feeder members
(scoops) that together form an annular aperture feeding the helical
pipes. The number of feeder members and pipes is selected depending
upon the design flow of the device. This enables a standard kit of
central support and pipe portions to produce e.g. a water turbine with a
fully annular inlet, regardless of the number of helical pipes selected
for a particular installation, by providing different feeder members for
respective numbers of helical pipes.
