Abstract

The power station is erected on an artificial island, formed on a sandbank in the open sea. This is six-sided with a mast (6) supporting a number of wind turbines placed at four of its corners. Four sides of the island are formed to act as ship berthing piers (2) to allow the ship to be berthed, so that it is protected from cross-winds irrespective of the wind direction. Pref. the rectangular power station building extends between the remaining two sides, with the wind turbine masts (6) at either end of each of these two sides, the roof of the building acting as a helicopter landing pad.

Description

- Large steam-wind composite power plant as

Environmentally friendly plant using a belt bench as a location far out from the mainland and use of there constantly at different heights prevailing winds eve in front of the mouth of the Elbe or the Bries Islands, there are so-called grinding sands or sandbanks, which in themselves, without sufficient Markings represent a serious danger to shipping. These sandbars ei @@ e @ sirh very well as a location for a large steam-wind composite power plant.

It is becoming more and more difficult for the strome @ generating companies to find the provide the required energy. The construction of nuclear power plants and even coal power plants is becoming more and more difficult, firstly due to the radiation hazards and secondly due to exhaust gases of coal-fired power plants in metropolitan areas.

In order to protect us as much as possible from these dangers, mine plants - which only devour a portion of the costs of a nuclear power plant open sea in a total area of about 250 x 250 m as an artificial island CA) be built from reinforced concrete.

The pollutants from the chimneys of four working in a network Coal-fired power plants, which cannot be coped with on the mainland, play the game the open sea does not matter, as there is always sufficient airflow here, to distribute the exhaust gases in the great heights of the chimneys of about 200 m.

These chimneys are designed so that they each have 4 large ones Can accommodate wind turbines at different heights.

The artificial island is built in such a way that it is the largest from the sea side Import coal ships (I) can moor, which would otherwise only be reloaded in a port would have to be, if the same is deep enough for such ships to be covered. At on the opposite side, i.e. towards the mainland, coastal ships (II) can nit local coal and are protected from possible storms through the island. There is also a jetty with stairs for small watercraft.

For quick unloading of the coal ships and simultaneous supply the boiler standing under the upper platform on the false ceiling Cranes with large loading capacities are available, which are on rails over turntables äe alternately on the outer ring as required, i.e. between the deep sea quay and the coastal quay drive and work. Next to the crane runways there are large open spaces under i @@ isch Coal bunker for a supply of several months. These coal stocks in the underground Bunkers can be driven directly to the boiler using an electric front loader because the whole island has an underwater floor the whole size of it.

The salt-free water for the steam boiler feed either comes through Deep drilling from the island platform us, thus at the same time as drinking water for the island crew, or a pipeline from a river or waterworks from the mainland here.

In the middle of the platform there is a switchgear or administration building, Above it is designed as a tower in order to be able to overlook the large-scale complex.

The crew or operating team of the large power plant can use Chopper on the upper platform or by ship at the coastal quay pier earth.

The chimneys are tapered in four steps by 50 cm each to the Take up the stages of the wind turbines. The generator room is from the windward side and the rotor head with the rotor blades pre-assembled. On the opposite side, the wind deflectors, which are angled by 90 degrees to each other, for turning into the respective Wind direction. The rotation is carried out by means of bevel gears and shafts on the or the turntable mounted on the turntable, so that the turbines are ahead of the wind being held.

The individual rotor blades of the turbines are rotatable with their shaft, inclined roller bearings in the @otorkopf. By centrifugal governor - similar to a flywheel governor with old steam engines - the rotor blades are depending on the set speed against spring resistances in or out of are turned. Air by electrical means Each individual turbine is switched in or out of operation from the control center set.

For the exhaust steam that is set up on the platform in aen generator shed three-stage steam turbines are two cooling resp.

Condensation storms available.

From de @ Abdampf we-de @ in winter via @ ärmeaustauscher at the same time all buildings and rooms on the artificial island (A) are heated.

Each of the four are turbines attached to the chimneys or concrete towers with its adjustable rotor blades has a dynamo or slow-running flywheel generator.

The generated energy is sent to the switching station on the Platform delivered. Connected in parallel, a larger battery is also charged, to the whole when all four steam and 16 wind power generators come to a standstill The system including all elevators, excavators, front loaders, etc. is still sufficient to be supplied with electricity. The same is in one of the storage rooms in the base of the respective Tower housed.

By interconnecting the four generators of a turbine tower a steady current flow even with different wind speeds or wind currents reached within the 200 meter high towers.

Due to the already mentioned possible installation of flywheel generators detdilen transmission gear, making a noiseless in on the wind turbine generator stations is achieved.

If this altB generation of generators should be too expensive, is also the use of new types of generators driven by a V-belt strap possible.

This total energy generated is underneath several cable harnesses water delivered to a distribution station on land. A relocation of such strong ones Cable to the coast shouldn't be a problem for riding, as there are now enough Experience with laying large diameter oil pipelines in the North Sea from the production platforms there should be made to the mainland, which is safe was much more difficult. There is also the risk of marine pollution in the event of damage to connection points.

Each of the towers has an elevator shaft next to the chimney with freight elevator. This facilitates the assembly and subsequent maintenance of the wind turbines and generators very simple. Bulky or heavy parts are picked up with the crane rotatable boom pulled up on the upper tower head. You enter from the elevator through an exit the stage with the turbine system revolving around the tower, via which you can reach the weatherproof generator room, in which the entire generator and control system is housed. In the event that the elevator fails, Two steel emergency ladders are built into the shaft for ascent or descent.

There are flashing lights in the upper part of the chimneys or towers for shipping. This possibility, a warning and light signal here at a height of 200 meters to have @ should be unique.

If one determines the costs of such a large-scale wind-coal power plant, one should come to very interesting figures. One would the billions for a nuclear power plant, or as recently shown on television, the enormous expense to the extraction of oil in the North Sea, one can probably for this sum create many such large-scale wind-coal power plants. The kottenlose 't raw material wind is likely to be included more and more in large-scale planning in order to find the raw material that is still available to stretch. Radiation hazards in the event of malfunctions and storage of radioactive residues As is well known, there is no such thing as coal and ind either.
