Definitions
- the invention relates to an operating method and a drive device for a large watercraft, e.g. for a fast, military, surface watercraft, which has at least one water jet propulsion (waterjet) under the ship, the propulsive energy by internal combustion engines, e.g. Gas turbines, is generated and the exhaust gases generated by the internal combustion engines' are distributed in the water by means of the water jet of the water jet under the ship.
- a large watercraft e.g. for a fast, military, surface watercraft
- waterjet water jet propulsion
- Drive device for a large watercraft also for a large civil watercraft, e.g. to indicate a fast ferry, a large yacht or the like, in which an undetectable operation without exhaust gas plume or emission-free can be achieved even without the use of electrical energy to achieve the march (normal travel) speed.
- the drive efficiency should be undiminished and the ship's resistance should be reduced. This is done by introducing exhaust gas bubbles into the hull boundary layer.
- the object is achieved in that the exit velocity of the water jet of the water jet corresponds to the requirements exhaust gas discharge and distribution is set. Because the speed of the water jet of the water jet is set in accordance with the requirements of exhaust gas introduction and distribution, and no longer, as was previously the case with water jets, in accordance with the requirements of ship speed, it is surprisingly advantageously possible, even at low speeds and possibly . Even when the ship is at a standstill, exhaust gases are discharged under the ship. By discharging the exhaust gases under the ship, even at low ship speeds or when starting the ship, there is also a very advantageous possibility for ships that do not have an electric drive to operate them at all speeds without an exhaust plume.
- the watercraft has at least one electrically driven water jet drive, the electrical energy being at least partially generated by combustion, e.g. Gas turbines, driven generators is generated.
- the drive components can thus be arranged particularly cheaply in the ship and used more effectively in the partial load range. It is possible to place the waterjet far ahead in the ship, e.g. at the beginning of the parallel trunk course. This has the advantage that the gas-water mixture generated by the waterjet flows around the entire hull to reduce friction.
- the exhaust gas is introduced into the water under the ship without increasing (compression) the exhaust gas pressure. So it can be advantageous to install compressors or exhaust gas ejectors for the pipe of the exhaust gases into the water. The efficiency of the drive system is also not reduced by the energy requirements of the compressors or ejectors.
- the water jet speed at the exit of the water jet from the water jet creates a vacuum region with a pressure which is below the exhaust gas pressure. This advantageously makes it possible to even increase the efficiency of the internal combustion engines, which is generally dependent on the exhaust gas back pressure.
- the speed of the water jet of the water jet can be set independently of the ship's speed.
- the speed of the water jet emitted by the waterjets is not independent of the speed of the ship. This could mean that the amount of exhaust gas generated by the internal combustion engines cannot be discharged in the part-load range, since the ship is traveling too slowly. This is prevented by the inventive design.
- the speed of the water jet of the water jet is adjusted by changing the cross section of the water jet.
- the speed of the water jet of the waterjet can also be adjusted by a controlled change in the speed of the water flowing through the waterjet, for example by changing rotor speeds, but particularly advantageously in that the change in the speed of the water flowing through the waterjet is regulated by adjusting elements, in particular by means of adjustable adjustment blades of the waterjet rotor.
- adjustable adjustable blades of the waterjet rotor it is even possible that when the ship starts up, a sufficiently fast water jet is already generated for the removal of the exhaust gases. It is also possible to start the ship without any exhaust fumes using a waterjet driven by an internal combustion engine, with high efficiency.
- the introduction of the exhaust gases into the water becomes completely independent of the ship's speed and ships that approach without exhaust gas and do not have stored or generated electrical energy can be executed. This is particularly important for low cost ships.
- the setting of the speed of the water jet of the water jet is carried out particularly advantageously by a controlled change in cross section of the water jet, e.g. via a cross-sectional nozzle at the water jet outlet.
- This is a mechanically particularly simple solution.
- a particularly favorable operating behavior arises if the cross-sectional change is caused by guide elements arranged in the interior of the water jet, e.g. axially displaceable pipe sections. Despite the guide elements, a low-friction and low-turbulence design of the water jet is possible. At the same time, a mechanically particularly simple and robust solution results.
- the change in cross-section is effected by guide elements, for example flaps, arranged on the outside of the water jet.
- the flaps which can be designed both perpendicularly to the water jet formation and also like an iris diaphragm, can be moved simply mechanically or hydraulically.
- the water jet can also be given a cross-section which is set in a regulated manner and deviates from a circular shape, in particular a square or rectangular cross-section, for example by means of a corresponding outlet nozzle shape and size, which are optimally adapted to the shape of the ship hydrodynamically (noise and ship resistance) can. So it is possible to realize a water jet shape adapted to the respective ship type, For example, for flat-going ships, a water jet in flat form without leaving the advantages of the water jet's speed, which is regulated independently of the ship's speed.
- the speed of the water jet of the waterjet is set between limit values that are independent of the ship's speed.
- limit values e.g. for the minimum speed of the water jet, it can be achieved that the exhaust gases are safely discharged in sufficient quantities, even if the ship is only moving slowly.
- the upper limit advantageously results from a free flow of the water jet with the highest possible water tightness.
- a drive device for carrying out the operating method for a watercraft with a water jet arranged under the ship, an underwater exhaust gas introduction device, e.g., flowing axially through the water jet drive jet, exiting the water jet generated by the water jet.
- a substantially round chamber for introducing the exhaust gases into the water under the ship is arranged.
- the underwater exhaust gas introduction device for introducing the exhaust gases into the water is designed as a coaxial exhaust nozzle segment.
- a coaxial exhaust gas nozzle segment ie a nozzle segment which is in relation to the exhaust gas space, which is the water jet of the Surrounding water jets, coaxial, the invention is particularly advantageous.
- a cross-sectionally adjustable middle element e.g. a telescopic device which effects the adjustment of the water jet speed in the underwater exhaust gas introduction device is arranged.
- the result is a coaxial exhaust nozzle segment with particularly good efficiency and a robust design. Its function is such that there is no increased nozzle noise even when the water jet cross-section changes. This is particularly important for Navy (Navy) ships.
- an outer element which is adjustable in cross section, e.g. a controllable aperture is arranged.
- the outer element for setting the water jet cross-section can also be used in combination with the inner element and allows a simple mechanical design, e.g. in the form of a lever-actuated adjusting device, the cross-sectional reduction of the waterjet water jet according to the invention.
- Both the inner and the outer element can be supplemented by the known waterjet deflection vanes for adjusting the water jet direction or also for reversing. As a result, the exit effect for the exhaust gases according to the invention is not impaired.
- the drive device has a pipe system for the exhaust gases in the coaxial exhaust nozzle segment, in which there is advantageously at least one back pressure-controlled non-return valve. This can prevent water from striking back into the pipe system and thus also into the internal combustion engines when the ship stops.
- the pipe system also advantageously has Controlled shut-off devices, such as flaps or slides, which are independent of the back pressure and are used in particular in port or when driving by means of a propeller drive.
- the walls and / or blades of the waterjet advantageously have a coating made of elastomeric material.
- This can e.g. Hard rubber, but also a fiber-reinforced plastic material. In this way, cavitation phenomena are prevented as well as noise insulation of the emerging water jet is achieved.
- Corresponding coatings are known from the field of centrifugal pumps, but it is new to also provide them for water jets.
- the drive device has at least one preferably retractable rudder propeller or cycloidal propeller as the control and propulsion element of the ship.
- the vacuum region advantageously provided at the waterjet water jet outlet thus readily results.
- the drive device for example in the case of electric drives, in addition to a generator, at least one further electrical energy source, e.g. Accumulators or fuel cell systems, which allow exhaust-free navigation of the ship.
- the rudder propeller can also be retracted in the bow area. Then the usual "bow thruster *" can be omitted.
- an internal combustion engine for starting the watercraft has an optionally switchable exhaust line into the water or into the atmosphere.
- sensors for pressure measurement are provided in the underwater exhaust gas introduction device for supplying the exhaust gases to the water jet of the waterjet; sensors for pressure measurement in the exhaust pipe system are also provided. In this way, safe operation can be achieved with simple and robust sensors.
- An automation system with automation devices is advantageously available for the control and regulation of the water jet as a function of the exhaust gas introduction, which relieves the ship's operating crew and prevents switching errors. Furthermore, coordinated control of the individual drive components can be achieved using ramp functions.
- the automation system acts not only on the elements on the waterjet which influence the waterjet speed and the pressure conditions, but also on the adjusting elements and closure elements in the exhaust pipe system.
- the automation system is advantageously arranged “on site *. It includes the automation of the internal combustion engine (gas turbine or diesel engine), the generator and the water jet, as well as the exhaust pipe system. It advantageously controls and regulates both the operational readiness (e.g. pressures and temperatures), starting and operation (e.g. speeds and positions of actuators) as well as the required electrical switching and actuating devices (e.g. circuit breakers, AC-AC or AC - DC actuators) ).
- a corresponding second automation system is at least partially in the overall drive automation. This results in an advantageous complete automation of the drive device in relation to the water jet as the drive component.
- the heat of the exhaust gases via a heat exchanger system for others Operating equipment, for example for the production of warm water and / or for desalination of sea water.
- the energy required for this can advantageously be reduced on board the respective ship.
- the drive device according to the invention is e.g. primarily controlled according to the speed requirement of the ship. On ships with one or more electric rudder propellers in the stern area, the propulsion required for the desired at relatively low speeds
- Ship speed is necessary to deliver, also a simultaneous operation of the water jets is provided.
- This has the advantage that the increased shape of the ship due to the arrangement of the water jets on the underside of the ship can be compensated. So there is no negative influence of the hull shape change required by the waterjets.
- a running of the water jets is advantageously provided for ships which, in addition to the water jets, also have electric rudder propellers or an electric simple propeller drive, at least from the speed range of 2 to 3 knots. From this speed, it is also possible to achieve the vacuum or zero pressure required for the introduction of exhaust gas by reducing the cross section of the waterjet water jet without having to work with adjusting blades in the waterjet.
- the adjustment blades of the Waterjet rotor no longer need to be set to the suction position, as when starting, even from 2 to 3 knots, but can be operated with the normal propulsion position of the Waterjet -Rotor blades to be worked.
- the waterjet adjustment position can therefore be optimized for propulsion.
- 1 shows the exhaust gas routing of a drive device in relation to the waterjet and in
- FIG. 3 shows a schematic diagram with the input and output variables on the waterjet.
- FIGURE 1 is an internal combustion engine, here e.g. a gas turbine of the type LM2500 from MTU.
- the gas turbine drives a generator 2, here e.g. a 16MW generator.
- the coaxial nozzle segment is designated by 3, in which the schematically indicated water jet 5 entrains the exhaust gas surrounding the water jet coaxially.
- the water jet 5 is generated by the rotor 4, which e.g. is driven by a rotor shaft.
- the double arrow 6 symbolizes the adjustability of the cross-section at the exit of the waterjet, in order to give it the necessary speed even at low speeds of the ship to challenge the exhaust gas from the area of the waterjet outlet.
- the speed of the emerging water jet can be set so high by a corresponding reduction in cross section that a vacuum is even created in room 3.
- Alternatively can
- Pressure can be set to 0 bar, so that the gas turbine or a diesel engine instead of the gas turbine has no loss in efficiency compared to a free escape of the exhaust gases into the atmosphere.
- the exhaust gases of the gas turbine 1 are led to the coaxially operating nozzle segments through the line 9, which is preferably formed immediately before the water jets when using twin water jets.
- shut-off valves 7 and 8 which are non-return flaps or controlled flaps, in order to prevent the water surrounding the ship's hull from kicking back into the line when it is at a standstill.
- pressure sensors can also be arranged, which serve to regulate the exhaust gas pressure in the respective areas by changing the exit speed of the water jet or the exit cross section from the line 9.
- the pressure sensors can be supplemented by further sensors, such as water intrusion detectors, valve position sensors etc.
- the sensor signals are given to the automation system (not shown in more detail), which e.g. also start-up ramps for the gas turbine, for the pumps of the heat exchanger 11 and for the
- Servomotor of the main gate valve 10 has.
- the automation system has the usual components for a ship propulsion system, so that an autonomously operable subsystem of ship automation is created.
- This subsystem is advantageously designed in such a way that, together with the internal combustion engine, the generator and the waterjet, as well as the pipelines required for this, there is a ship equipment component which can be used essentially unchanged for different ship types and ship sizes. It is particularly advantageous if this drive unit is installed in the ship in a prefabricated form when the keel is laid. The number of installed ship equipment components depends on the size of the ship.
- 12 denotes the rotor blades, which are arranged on a rotor hub 15.
- the rotor hub 15 can be driven in a manner not detailed, for example by a drive shaft 23 engaging from the front. However, it can also be designed as an inner rotor, the drive being carried out by windings 16, which are indicated schematically.
- the stator also has the stator blades 13, which, if necessary, for a better starting behavior of the ship, if no separate propeller drive is available in the stern or in the bow, as well as the rotor blades 12, are designed as adjusting blades and, in this respect, supplement the intended blade adjustment for a water jet that can be approached.
- the stator hub 14 On the output side, the stator hub 14 has hydraulically actuable tubular elements 17 which can be extended to different extents and reduce the cross section in the annular space 22 in such a way that the water velocity is high enough to exhaust the exhaust gases of the internal combustion engine through the pipeline 18 into the annular space 22 come in, carry along.
- the adjustability of the adjustment elements 17 is indicated by the thick double arrow 20.
- the annular space 22 is closed off by walls 21, into which e.g. ring baffles can also be installed in order to achieve an external adjustment of the outlet cross section of the water from the waterjet.
- Such an adjustment can take place by means of an iris diaphragm which contains segments which can be displaced in relation to one another in the form of tubular sections.
- An outer cone that is moved towards the inlet side of the water also has a corresponding effect.
- the inner contour of the outer cone can roughly correspond to the contour of the outer annular space boundary.
- the inflow of water is indicated by the arrow 19, it can result both from the ship's travel through the water and from a suction effect of the water jet, which arises when the rotor and possibly the stator blades are adjusted accordingly ,
- the pipe diameter, the spacing in the waterjet, the blade profiles, the design of the elements that change the cross-section of the emerging water jet are coordinated with each other and specific for each drive device.
- the drive directions are therefore preferably designed as autonomously operable devices which are then assigned in different numbers, for example individually or in pairs, to a respective ship type.
- 25 denotes a longitudinally cut water jet with the entry plane II and the exit plane I for the water flowing through the water jet.
- the pressure and speed relationships on the Waterjet can be described by the mass conservation equation and the integrated momentum equation. The specialist can use this to calculate the required speeds and beam cross sections in the waterjet.
- the application of the equations results from the calculation example which refers to FIG. 3.
- An example table shows the speed range that is important according to the invention. As can be seen, the discharge rate of the water jet is so great that any amount of exhaust gas resulting in practical operation can be safely discharged.
- Pi mean dynamic pressure component in the entry level Pa
- Vn average speed in the exit plane m / s Pn average dynamic pressure component in the exit plane Pa T: the thrust generated N
- Column 10 shows that from 2 nodes there are negative pressures in the exit plane of the drive.
- the calculated flow rate in column 13 is significantly higher than the minimum flow rate required to transport the exhaust gases.
