2. Description of the Related Art In ships, a power generation type device is well known in which a diesel main engine generates propulsive force, while steam is generated using exhaust heat generated from the main engine, and the steam drives a generator to generate electricity.

進軸に伝達させる船舶推進装置が知られている。 In addition, as shown in Japanese Utility Model Publication No. 15084/1984, a speed increasing device is connected to the transmission device between the main engine and the propulsion shaft, and the speed increasing device and the generator are connected by a clutch to reduce the amount of steam generated. Time is a part of the output of the main engine that drives the generator via the speed increaser and clutch.If the amount of steam generated is large, the excess rotational power of the generator driven by steam is used to drive the generator through the speed increaser and the speed increaser. A marine vessel propulsion device is known in which the information is transmitted to the propulsion shaft via the propulsion shaft.

However, when the power generator is driven by the main engine, this propulsion device can be operated within a narrow range of the main engine output (i.e., the generator's rotation speed depends on the main engine's rotation speed). Since the generated steam is simultaneously supplied to the generator side, there is a problem that even if the generated steam is attempted to be used in other miscellaneous steam systems, the required pressure is too low to use it.

る。 In addition, when the amount of steam generated is large and the surplus output is used to drive the propulsion shaft, the rotation speed of the generator is uniquely determined by the rotation speed of the main engine, so propulsion is carried out while maintaining normal power supply capacity. To drive the shaft, the main engine output can only be used within a very limited range, and there is a problem in that the exhaust heat of the main engine cannot be used effectively.

In order to achieve the above object, the present invention includes a diesel main engine that drives a propulsion machine, a steam generator that generates steam using the exhaust heat of the main engine, and a turbine power generator that is driven by the steam from the steam generator. a turbine pressure regulating valve that is connected to the steam supply pipe from the steam generator to the turbine generator and adjusts the steam pressure supplied to the turbine generator; and a turbine pressure regulating valve that is installed on the turbine generator and adjusts the air supply to the turbine. In a marine generator drive system equipped with a speed governor that controls the rotational speed of the generator, a multi-stage switching speed increasing device capable of switching the increase/deceleration ratio in multiple stages is connected to the main engine, and the multi-stage switching speed increasing device is connected to the clutch. A miscellaneous pressure regulating valve is connected in parallel with the turbine pressure regulating valve to regulate the pressure of the steam generator by regulating the supply air on the turbine side. A switching valve for switching the valve is provided, and another miscellaneous steam supply system is connected to the steam generator, and when the amount of steam generated is large, steam is supplied to the turbine generator via the turbine pressure regulating valve. It drives the turbine generator and transmits its surplus torque to the propulsion engine through the clutch, and when the amount of steam generated is small, the output of the main engine is driven through the multi-stage speed increaser and the clutch to drive the turbine. The miscellaneous pressure regulating valve is used to maintain the steam in the miscellaneous steam supply system above the required steam pressure, and by installing a multi-stage speed increasing device, when the main engine drives the turbine generator, the rotational speed of the main engine is controlled. In contrast, the rotational speed of the turbine generator can be set to the allowable rotational speed by setting the increase/decrease ratio of the multi-stage switching speed increaser, and conversely, when the turbine generator is driven by steam, the surplus rotational power can be used to drive the main engine. Therefore, the power supplied to the turbine generator can be matched to the required amount, and the amount of steam generated is small, so when the main engine drives the turbine generator, it is necessary to adjust the pressure The valve regulates the air supply to the turbine generator and maintains the steam pressure to the miscellaneous steam supply system at the required pressure, thereby guaranteeing the amount of steam supplied. As a result, the exhaust heat of the main engine can be used effectively, greatly expanding the scope of energy-saving operation.

転速度を制御するようになつている。 The steam generator S consists of an exhaust gas economizer S 1 that generates steam from the exhaust gas of the main engine 2 and a steam drum S 2. The liquid in the steam drum S 2 is supplied to the exhaust gas economizer S from the water supply section W via the boiler water circulation pump P. 1
The water is heated through the feed water heating section 1s and returned to the steam drum S2 via the evaporation section S3 , where the steam separated into gas and liquid is transferred to the heat exchange section 1f of the exhaust gas economizer S1.
The pressure is increased through the steam supply pipe 8 and then supplied to the steam turbine 6 of the turbine generator 7 . A part of the steam from the steam drum S 2 is also supplied to the miscellaneous steam supply system 10 .

次に、本発明装置の動作を説明する。 Next, the operation of the device of the present invention will be explained.

２の負荷を低減させるようにする。 When the main engine 2 is operated near the normal output, there is a sufficient amount of steam recovered from exhaust heat, and in that case, the steam from the steam generator S is transferred from the steam supply pipe 8 through the switching valve 14. Turbine pressure regulating valve 12
The steam is supplied to the steam turbine 6 through the steam turbine, and the turbine generator 7 is driven. At this time, the speed governor 9 controls the air supply amount in order to suppress the rotation speed of the turbine generator 7 to an allowable rotation speed in response to load fluctuations of the turbine generator 7, and the turbine pressure regulating valve 12 controls the amount of air supplied to the turbine generator 7 in order to suppress the rotation speed to a permissible rotation speed. It seems that the pressure is not controlled. In addition, when there is a surplus of steam in the steam drive of the turbine generator 7, the clutch C1 is engaged, and the surplus steam energy is transferred to the propulsion machine 3 side via the multi-stage switching speed increasing device 5. and reduce the load on the main engine 2.

That is, when the amount of exhaust heat is small and the amount of generated steam is small, the generated steam alone cannot provide enough turbine output to drive the turbine generator 7, so the main engine 2
A part of the side output drives the turbine generator 7 via the multi-stage switching speed increaser 5 and the clutch C1 .
At this time, the increase/decrease ratio of the multi-stage switching speed increaser 5 is changed so that the rotation speed of the turbine generator 7 becomes the allowable rotation speed with respect to the rotation speed of the main engine 2. to drive. In addition, the steam generated in the steam generator S is supplied to the miscellaneous steam supply system 10.
However, if the generated steam is directly supplied to the steam turbine 6, then the miscellaneous steam supply system 10
When the required steam pressure cannot be obtained, the switching main valve 14 is closed, the other switching main valve 13 is opened, the miscellaneous pressure regulating valve 11 regulates the amount of steam flowing to the steam turbine 6, and the steam generator S In order to maintain the steam pressure supplied to the miscellaneous steam supply system 10 at the required pressure.

燃料費の節減となる。 In this way, conventionally, the main engine output (mechanical output and thermal output) could only be used within a narrow range, and when outside this range, another diesel generator had to be operated. However, the device of the present invention is now able to generate the power required within the ship without having to operate other diesel generators within the range of 40 to 90% of the main engine output rating.
In other words, the degree of exhaust heat recovery is improved and fuel costs required for power generation are reduced.
このような利点は主機を部分負荷で使用するつ
