Description

【０００１】
【発明の属する技術分野】
本発明は船舶等における貯蔵タンク中の燃料油の加熱方法に係り、詳細には、Ｃ重油等の燃料油を貯蔵タンクから移送ポンプにより澄タンクに移送して加熱し、ここで加熱された燃料油を貯蔵タンクに流下混合して該タンク中の燃料油を所望温度に加熱する燃料油の加熱方法に係り、特に、貯蔵タンク中の燃料油の加熱不足による粘度上昇を防ぎ、貯蔵タンクの燃料油を常に移送容易な温度に保つ貯蔵タンク中の燃料油の加熱方法に関する。
【０００２】
【従来の技術】
船舶等において、燃料油を機関に供給する際に、通常、燃料油を燃料油貯蔵タンクから移送ポンプによって移送管を通して燃料油澄タンクに送り、ここで燃料油を加熱の後、燃料油サービスタンク（燃料油小出タンク）および燃料油清浄機等を介して機関に供給している。このとき、燃料油貯蔵タンク中の燃料油は粘度を低くして移送しやすくするために、加温されることか必要である。
【０００３】
燃料油貯蔵タンク中の燃料油の加熱方法として、従来、図１における真空センサ７および温度センサ８を備えない装置を用いた方法が知られている。
【０００４】
これを図１を用いて詳述すると、まず、澄タンク４に内蔵された図示しない加熱装置によって澄タンク４中の燃料油を加熱しておき、この加熱された燃料油を吸入管６を通じて流下ポンプ５の作動により貯蔵タンク１に流下する。貯蔵タンク１中にはＣ重油等の燃料油が張り込んであり、この燃料油が流下された加熱燃料油と部分的に混合され、３６℃〜４０℃の温度に部分的に加熱される。
【０００５】
次いで、貯蔵タンク１中の燃料油を移送管２を通じ、移送ポンプ３の作動により澄タンク４に移送する。澄タンク４中の燃料油は図示しない加熱装置により加熱され、いずれも図示しない燃料油サービスタンクおよび燃料油洗浄機を経て機関に供給される。同時に、この加熱された燃料油の一部は流下ポンプ５（シフターポンプ５）の作動により吸入管６を経て貯蔵タンク１に流下され、該タンク１中の燃料油を部分的に加熱する。
【０００６】
【発明が解決すべき課題】
貯蔵タンク１中のこのような加熱は通常、加熱された燃料油を澄タンク４から貯蔵タンク１に流下する時間（加熱時間）、および貯蔵タンク１の燃料油を澄タンク４に移送する移送時間を例えば４５分・１５分の時間サイクルとすることによって行われる。
【０００７】
しかし、寒冷水域等の場所では、移送しようとする貯蔵タンク１中の燃料油の加熱不足が発生し、このため、移送管２を流れる燃料油の粘度が上昇して吸入抵抗が大きくなり、場合によっては移送ポンプの吸入圧が真空になってしまい、移送困難になる。
【０００８】
そこで、本発明の目的は貯蔵タンクから澄タンクに移送される燃料油の加熱状態を検出し、加熱不足による燃料油の粘度上昇を防いで貯蔵タンクの燃料油を常に移送可能な温度に保ち、上述の公知技術に存する欠点を改良した貯蔵タンク中の燃料油の加熱方法を提供することにある。
【０００９】
【課題を解決するための手段】
上述の目的を達成するため、本発明によれば、燃料油を貯蔵タンクから移送ポンプにより澄タンクに移送して加熱し、ここで加熱された燃料油を貯蔵タンク中の燃料油に流下混合して該燃料油を所望温度に加熱する燃料油の加熱方法において、貯蔵タンクから澄タンクに移送される燃料油の加熱状態を検出し、この検出データに基づいて、澄タンクから貯蔵タンクに流下する燃料油の流量ないしは温度を、貯蔵タンクの燃料油が所望の温度を保持するように調整することを特徴とする。
【００１０】
【発明の実施の形態】
以下、本発明を添付図面を用いて詳述する。
【００１１】
図１は貯蔵タンク中の燃料油の加熱システムを表したフローシートであって、まず、貯蔵タンク１中にＣ重油等の燃料油を所望量、張り込んでおくと同時に、澄タンク４に内蔵された図示しない加熱装置によって澄タンク４中の燃料油を加熱しておき、この加熱された燃料油を吸入管６を通じて流下ポンプ５の作動により貯蔵タンク１に流下する。貯蔵タンク１では、貯蔵された燃料油が流下された加熱燃料油と部分的に混合され、３６℃〜４０℃の温度に部分的に加熱される。この加熱により、燃料油の粘度は下がる。
【００１２】
次いで、貯蔵タンク１中の部分的に加熱された燃料油を移送管２を通じ、移送ポンプ３の作動により澄タンク４に矢印方向に移送する。澄タンク４に移送された燃料油は図示しない加熱装置により、所望温度、例えば７０℃〜８０℃に加熱され、いずれも図示しない燃料油サービスタンクおよび燃料油清浄機を経て機関に供給される。同時に、この加熱された燃料油の一部は流下ポンプ５（シフターポンプ５）の作動により、吸入管６を経て貯蔵タンク１に流下され、この流下された燃料油により、貯蔵タンク１中の燃料油を部分的に加熱する。
【００１３】
本発明の特徴は図１の加熱システムの移送管２に、さらに真空サンセ７および温度センサ８を設けて貯蔵タンク１から澄タンク４に移送される燃料油の加熱状態を検出し（検出工程）、この検出データに基づいて、澄タンク４から貯蔵タンク１に流下する加熱燃料油（７０℃〜８０℃）の流量ないしは温度を、貯蔵タンク１の燃料油が所望の温度（３６℃〜４０℃）を保持するように調整し（調整工程）、上述検出工程と調整工程を併用したことに存する。
【００１４】
上述の検出工程としては、次の（ａ）〜（ｃ）の各工程が挙げられる。
【００１５】
（ａ）真空センサ７を用いて、移送ポンプ３の吸入圧力を検出することにより燃料油の加熱状態を検出する。真空度が４００〜４５０ｍｍＨｇ　であれば正常であるが、４００ｍｍＨｇ　以下の場合、異常とする。
【００１６】
（ｂ）温度サンセ８を用いて、移送される燃料油の温度を検出することにより、燃料油の加熱状態を検出する。温度が３６℃〜４０℃であれば正常であるが、３６℃以下の温度の場合、異常とする。
【００１７】
（ｃ）移送ポンプ３の運転時間を検出することにより、燃料油の加熱状態を検出する。例えば、正常に加熱されているときの移送ポンプ３の運転時間、すなわち、貯蔵タンク１の燃料油を澄タンク４に移送する移送工程の時間が１５分の場合、この時間を過ぎても運転しているときには異常とする。
【００１８】
さらに、これらの検出工程によって得られた検出データに基づき、調整工程を行う。調整工程としては、次の（１）〜（４）各工程が挙げられる。
【００１９】
（１）燃料油が澄タンク４から貯蔵タンク１に流下する時間（加熱時間）と、燃料油が貯蔵タンク１から澄タンク４に移送する移送時間のサイクル、すなわち、加熱・移送時間のサイクルを短くして、貯蔵タンク１の燃料油が所望の温度を保持するように調整する。加熱・移送時間のサイクルを短くすることにより、貯蔵タンク１内での燃料油の熱放散が少なくなる。例えば、加熱４５分、移送１５分のサイクルを加熱２０分、移送７分、あるいは加熱１５分、移送１５分のサイクルにする。
【００２０】
（２）澄タンク４から加熱された燃料油を吸入管６を経て貯蔵タンク１流下させる際、燃料油の流量を変化させることにより貯蔵タンク１の燃料油が所望の温度（３６℃〜４０℃）を保持するように調整する。流量の変化は流下ポンプ５（シフターポンプ５）の回転数をインバータにより変化させて行う。例えば、流量を通常の２倍に増加させて調整する。
【００２１】
（３）澄タンク４から貯蔵タンク１に流下する燃料油の温度を上げて、貯蔵タンク１の燃料油が所望の温度（３６℃〜４０℃）を保持するように調整する。例えば、吸入管６における流下ポンプ５の下流側にヒータ９を設け、このヒータにより加熱して燃料油の温度を通常の１．２倍に上げる。
【００２２】
（４）燃料油を澄タンク４から移送ポンプ３の吸入側に流下、加熱する加熱工程と、燃料油を貯蔵タンク１から澄タンク４に移送する移送工程を同時に行って、移送ポンプ３を通過する燃料油が所望の温度（３６℃〜４０℃）を保持するように調整する。すなわち、移送ポンプ３の運転中に、流下ポンプ５（シフターポンプ５）を運転モードに自動的に切り換える。この結果、加熱された燃料油が移送ポンプ３の吸入側に流れ、移送ポンプ３の負荷が減少する。なお、通常運転では、移送ポンプの運転中は流下ポンプ５は停止している。
【００２３】
（５）移送ポンプ３を強制的に停止させると同時に、流下ポンプ５を運転することにより加熱された燃料油のみを貯蔵タンク１中の燃料油に流下混合し、貯蔵タンク１の燃料油が所望の温度（３６℃〜４０℃）を保持するように調整する。なお、通常の運転では、移送ポンプ３は澄タンク４が満杯になったときに停止する。この停止は澄タンク４の上部フロートスイッチ（図示せず）によって行われる。
【００２４】
上述の検出工程および調整工程は任意の一つまたは複数をそれぞれ任意に組み合わせることにより行われる。
【００２５】
【発明の効果】
上述の本発明は燃料油を貯蔵タンク１から澄タンク４に移送して加熱し、この加熱された燃料油を貯蔵タンク１の燃料油に流下混合して所望温度に加熱するシステムにおいて、燃料油の加熱状態を検出する検出工程と、この検出データに基づいて、澄タンク４から貯蔵タンク１に流下する燃料油を、貯蔵タンク１の燃料油が所望の温度（３６℃〜４０℃）に保持するように調整する調整工程とを組み合わせて行うようにしたから、貯蔵タンク１中の燃料油の加熱不足による粘度上昇を防ぎ、貯蔵タンク１中の燃料油を常に移送可能な温度に保つことができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for heating fuel oil in a storage tank of a ship or the like, and in particular, transfers fuel oil such as C heavy oil from a storage tank to a clear tank by a transfer pump and heats the fuel oil. The present invention relates to a method for heating fuel oil, in which oil flows down into a storage tank and heats the fuel oil in the tank to a desired temperature. The present invention relates to a method for heating fuel oil in a storage tank that always keeps oil at a temperature that allows easy transfer.
[0002]
[Prior art]
In a ship or the like, when supplying fuel oil to an engine, usually, the fuel oil is sent from a fuel oil storage tank to a fuel oil clear tank through a transfer pipe by a transfer pump, where the fuel oil is heated and then the fuel oil service tank. (Fuel supply tank) and a fuel oil purifier. At this time, the fuel oil in the fuel oil storage tank needs to be heated in order to lower the viscosity and facilitate the transfer.
[0003]
As a method for heating the fuel oil in the fuel oil storage tank, a method using a device without the vacuum sensor 7 and the temperature sensor 8 in FIG. 1 is conventionally known.
[0004]
This will be described in detail with reference to FIG. 1. First, the fuel oil in the clear tank 4 is heated by a heating device (not shown) built in the clear tank 4, and the heated fuel oil flows down through the suction pipe 6. It flows down to the storage tank 1 by the operation of the pump 5. Fuel oil, such as heavy fuel oil C, is inserted into the storage tank 1, and this fuel oil is partially mixed with the heated fuel oil that has flowed down, and is partially heated to a temperature of 36 ° C to 40 ° C.
[0005]
Next, the fuel oil in the storage tank 1 is transferred to the clear tank 4 by the operation of the transfer pump 3 through the transfer pipe 2. The fuel oil in the clear tank 4 is heated by a heating device (not shown) and supplied to the engine via a fuel oil service tank and a fuel oil washer (not shown). At the same time, a part of the heated fuel oil flows down to the storage tank 1 through the suction pipe 6 by the operation of the downflow pump 5 (shifter pump 5), and partially heats the fuel oil in the tank 1.
[0006]
[Problems to be solved by the invention]
Such heating in the storage tank 1 usually takes the time to flow heated fuel oil from the clear tank 4 to the storage tank 1 (heating time) and the transfer time to transfer the fuel oil in the storage tank 1 to the clear tank 4. For example, a time cycle of 45 minutes and 15 minutes.
[0007]
However, in a place such as a cold water area, insufficient heating of the fuel oil in the storage tank 1 to be transferred occurs, and therefore, the viscosity of the fuel oil flowing through the transfer pipe 2 increases and the suction resistance increases. In some cases, the suction pressure of the transfer pump becomes vacuum, making transfer difficult.
[0008]
Therefore, an object of the present invention is to detect the heating state of the fuel oil transferred from the storage tank to the clear tank, prevent the increase in the viscosity of the fuel oil due to insufficient heating, always keep the fuel oil in the storage tank at a temperature at which the transfer is possible, It is an object of the present invention to provide a method for heating fuel oil in a storage tank, which ameliorates the above-mentioned disadvantages of the prior art.
[0009]
[Means for Solving the Problems]
To achieve the above object, according to the present invention, fuel oil is transferred from a storage tank to a clear tank by a transfer pump and heated, and the heated fuel oil is mixed with the fuel oil flowing down in the storage tank. In the fuel oil heating method for heating the fuel oil to a desired temperature, a heating state of the fuel oil transferred from the storage tank to the clear tank is detected, and the fuel oil flows down from the clear tank to the storage tank based on the detected data. The flow rate or the temperature of the fuel oil is adjusted so that the fuel oil in the storage tank maintains a desired temperature.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[0011]
FIG. 1 is a flow sheet showing a fuel oil heating system in a storage tank. First, a desired amount of fuel oil, such as heavy fuel oil C, is put into the storage tank 1 and is simultaneously installed in the clear tank 4. The fuel oil in the clear tank 4 is heated by a heating device (not shown), and the heated fuel oil flows down to the storage tank 1 by the operation of the down-flow pump 5 through the suction pipe 6. In the storage tank 1, the stored fuel oil is partially mixed with the heated fuel oil that has flowed down, and is partially heated to a temperature of 36 ° C. to 40 ° C. This heating lowers the viscosity of the fuel oil.
[0012]
Next, the partially heated fuel oil in the storage tank 1 is transferred through the transfer pipe 2 to the clear tank 4 by the operation of the transfer pump 3 in the direction of the arrow. The fuel oil transferred to the clarifying tank 4 is heated to a desired temperature, for example, 70 ° C. to 80 ° C., by a heating device (not shown), and is supplied to the engine via a fuel oil service tank and a fuel oil purifier (not shown). At the same time, a part of the heated fuel oil flows down to the storage tank 1 through the suction pipe 6 by the operation of the downflow pump 5 (shifter pump 5), and the fuel oil in the storage tank 1 is discharged by the downflowed fuel oil. Heat the oil partially.
[0013]
A feature of the present invention is that the heating pipe of the heating system of FIG. 1 is further provided with a vacuum sensor 7 and a temperature sensor 8 to detect the heating state of the fuel oil transferred from the storage tank 1 to the clear tank 4 (detection step). Based on the detected data, the flow rate or the temperature of the heated fuel oil (70 ° C. to 80 ° C.) flowing down from the clear tank 4 to the storage tank 1 is determined by determining the fuel oil in the storage tank 1 at the desired temperature (36 ° C. to 40 ° C.). ) Is maintained (adjustment step), and the detection step and the adjustment step are used in combination.
[0014]
The above-described detection steps include the following steps (a) to (c).
[0015]
(A) The heating state of the fuel oil is detected by detecting the suction pressure of the transfer pump 3 using the vacuum sensor 7. It is normal if the degree of vacuum is 400 to 450 mmHg, but it is abnormal if it is 400 mmHg or less.
[0016]
(B) The heating state of the fuel oil is detected by detecting the temperature of the transferred fuel oil using the temperature sensor 8. It is normal if the temperature is 36 ° C to 40 ° C, but abnormal if the temperature is 36 ° C or lower.
[0017]
(C) The heating state of the fuel oil is detected by detecting the operation time of the transfer pump 3. For example, when the operation time of the transfer pump 3 during normal heating, that is, the transfer step of transferring the fuel oil in the storage tank 1 to the clear tank 4 is 15 minutes, the operation is continued even after this time. When it is, it is abnormal.
[0018]
Further, an adjustment step is performed based on the detection data obtained in these detection steps. The adjustment step includes the following steps (1) to (4).
[0019]
(1) The cycle of the time during which the fuel oil flows down from the clear tank 4 to the storage tank 1 (heating time) and the cycle of the transfer time during which the fuel oil is transferred from the storage tank 1 to the clear tank 4, that is, the cycle of the heating / transfer time. It is shortened and adjusted so that the fuel oil in the storage tank 1 maintains a desired temperature. By shortening the cycle of the heating / transfer time, heat dissipation of the fuel oil in the storage tank 1 is reduced. For example, a cycle of heating 45 minutes and transfer 15 minutes is changed to a cycle of heating 20 minutes, transfer 7 minutes, or heating 15 minutes and transfer 15 minutes.
[0020]
(2) When the fuel oil heated from the clear tank 4 flows down the storage tank 1 through the suction pipe 6, the fuel oil in the storage tank 1 is heated to a desired temperature (36 ° C to 40 ° C) by changing the flow rate of the fuel oil. ) To keep it. The flow rate is changed by changing the rotation speed of the downflow pump 5 (shifter pump 5) by an inverter. For example, the flow rate is adjusted by increasing the flow rate twice as usual.
[0021]
(3) The temperature of the fuel oil flowing down from the clear tank 4 to the storage tank 1 is increased so that the fuel oil in the storage tank 1 maintains a desired temperature (36 ° C. to 40 ° C.). For example, a heater 9 is provided in the suction pipe 6 on the downstream side of the downflow pump 5, and the heater 9 is heated to increase the temperature of the fuel oil to 1.2 times the normal temperature.
[0022]
(4) The heating step of heating the fuel oil flowing down from the clear tank 4 to the suction side of the transfer pump 3 and the transferring step of transferring the fuel oil from the storage tank 1 to the clear tank 4 are performed simultaneously, and the fuel oil passes through the transfer pump 3. The fuel oil is adjusted so as to maintain a desired temperature (36 ° C. to 40 ° C.). That is, during the operation of the transfer pump 3, the downflow pump 5 (shifter pump 5) is automatically switched to the operation mode. As a result, the heated fuel oil flows to the suction side of the transfer pump 3, and the load on the transfer pump 3 decreases. In the normal operation, the downflow pump 5 is stopped during the operation of the transfer pump.
[0023]
(5) At the same time that the transfer pump 3 is forcibly stopped, only the fuel oil heated by operating the down-flow pump 5 is mixed down with the fuel oil in the storage tank 1 so that the fuel oil in the storage tank 1 is desired. (36 ° C to 40 ° C). In a normal operation, the transfer pump 3 stops when the clear tank 4 is full. This stop is performed by an upper float switch (not shown) of the clear tank 4.
[0024]
The above-described detection step and adjustment step are performed by arbitrarily combining one or a plurality of arbitrary ones.
[0025]
【The invention's effect】
The present invention described above relates to a system in which fuel oil is transferred from the storage tank 1 to the clear tank 4 and heated, and the heated fuel oil is mixed down with the fuel oil in the storage tank 1 and heated to a desired temperature. And the fuel oil flowing down from the clear tank 4 to the storage tank 1 is maintained at a desired temperature (36 ° C. to 40 ° C.) based on the detection data. It is possible to prevent a rise in viscosity due to insufficient heating of the fuel oil in the storage tank 1 and always maintain the temperature at which the fuel oil in the storage tank 1 can be transferred. it can.
