COGENERATION TURBINES FOR POWER AND DESALINATION OF SEA WATER

TURBINES DE COGENERATION POUR LA PRODUCTION D`ENERGIE ET LE DESSALEMENT DE L`EAU DE MER

English Abstract

By using the gas turbine and closed cycle gas/(air or nitrogen) turbine in
cascade way we can get the
required heat for the heat exchanger chamber (for adding heat) in the closed
cycle gas turbine, by
using the heat diverted with exhaust gases from the open cycle gas turbine.
Also we can get the heat
from nuclear plant instead the open cycle gas turbine if it is available. When
we get the very hot air
to the heat exchanger chamber (for cooling the air) after leave the turbine in
the closed cycle gas/air
turbine, we use the sea water in multi heat exchanger to cool the air and use
the heat make
desalination of the sea water, so at the end we can produce fresh water and
electricity by the open
and closed gas turbine same time.

Cogeneration Turbines for Power and Desalination of Sea Water
Background of the innovation
There are several inventions about desalination. All of it focused on getting
the heat just from the
sun (solar energy). It wouldn't produce a good quantity of fresh water and not
steady supplying of
energy because the limited time of the heat source (nights and cloudy days
effect).
In my innovation I offer to use the open cycle gas turbine as the source of
the heat and submit it to
the closed cycle gas/air turbine, which need the heat in one phase of the
close cycle (heat exchanger
B2, B3).
After the very hot air leave the turbine (B4) it need to cool down before go
to the compressor (B1).
That usually done by the draft air in the second heat exchanger.
I offer to use the sea water throw multi heat exchangers (B6, B7, B8) in a way
to make desalination
for the sea water and cooling down the air of the closed cycle before enter
the compressor (B1).
By this way the cogeneration of open and closed cycle gas turbines can produce
electricity together
and the closed cycle turbine can produce fresh water from the sea water same
time.
I added a way to use the solar heat in cooperation with the heat form the open
cycle gas turbine in
(B3) of the heat exchangers as a second source of heat which could save some
energy for the open
cycle gas turbine.
Description of the process.
In the open cycle gas turbine (A) air enter to compressor (Al), than to
combustion chamber (A2),
than very hot high pressured gases from (A2) hit the turbine (A3), leaving the
turbine as very hot
exhaust gases.
These gases enter the first heat exchanger (B2) and go throw iron pipes, which
divided to 2, 3 or
more pipes inside the heat exchanging chamber with insulation around each.
Pipes leave the chamber and back to be one pipe again going to (B3).
The warm compressed air (or nitrogen) coming from (B3) going to chamber (B2)
throw cupper tube
which divided inside the chamber to coil tubes each inside one of the iron
pipes. The coil tubes
should be in the middle of the iron pipes with no touch to the pipe wall.
At the end of the pipes the coil tubes back to be connected again form one
pipe goes out of B2 and
the very hot compressed air goes to the turbine (B4).
The air and the very hot gases going in posit direction to each other.

In the chamber (B3) it is similar in design to chamber (B2) except that the
air coming from the
compressor (B1) to (B3) and leave to (B2) as a compressed worm or hot air in
copper pipes and the
partially hot gases coming in the copper coil tubes from (B2) going in the
middle of each pipe in the
chamber (B3) and leave from the other side to reconnected in one tube going to
the exhaust.
Instead of direct insulations to the pipes it's packed with materials can get
very hot by solar heat and
transfer it to the tube where the flow at the air. These materials could be
(lava stones or coal).
The outside wall of the chamber made of glass on the top and the two sides to
attract sun rays in
morning time which could be directed in by reflector mirrors. These glasses
panels could cover by
insulators after sun set till sun rise again. The bottom of the chambers is
iron and has stays to
supports the pipes and the pipes has supports to support the coil tubes inside
as in the drawing (B3).
After the air left the turbine (B4) it goes to multi heat exchanger to cool
down which use sea water
to absorb the heat from the air (B6, B8) then the cool air goes to the
compressor (B1) to start the
cycle again.
The chamber (B6) as in the drawing, has multi sets of coil tubes getting the
very hot air from (B4)
going throw several coil tubes in the chamber (B6) and leave from there to
forming one tube has
warm air going to (B8).
A pipe bring the partially warm sea water from (B8) feeding several atomizers
on the wall of the
chamber(B6) to atomize the water as drops dropping in the chamber on the top
of the sets of tubes
which have the hot air inside.
Most of the drops evaporate by pulling the heat out from the air in the pipes
and evaporate in form
of gases going up to the curved dome of the chamber (B6) and guided out throw
pipe to outside of
the chamber by suction fan to (B7). The rest of the drops fall and gathering
in the bottom of (B6)
and going throw pipe to rejoin the warm water coming from (B7 and B8) to the
atomizers again.
In the chamber (B8) it has sets of coil tubes immersed in the sea water which
filled up the chamber
(B8) totally and coming to the chamber from the bottom drive from the sea by
water pump to the
chamber and leave from the top of the chamber after getting warm and
extracting the rest of the heat
in the air and go to (B6). The air leave the chamber cool going to the
compressor (B1).
In (B7) the hot water vapour in form of gases coming to the chamber from the
side wall above the
level of the formed fresh water. The hot gases going up throw the sets of
pipes hanged up
horizontally in the chamber and carried in direct sea water pushed by water
pump.
The warm sea water leave the chamber (B7) in one pipe after exchanging the
heat and cooling the
water vapour during its trip going up make lots of vapour condensed and drop
by gravity in the
basin bottom of the chamber as fresh water and pulled out.
What left of the vapour going out from the top side of the chamber in a pipe
to join the hot water
vapour pipe and going again to the chamber to repeat the cycle.
