最適な粘度を求める事が困難であった。Conventionally, the conventional method for adjusting the viscosity of heavy oil was to determine the heating temperature of the fuel oil by first knowing the properties of the incoming fuel oil and finding the optimum viscosity for combustion in the engine using a heavy oil viscosity-temperature relationship diagram. Due to the soaring price of fuel oil, attempts have been made to use fuel oil automatic mixers to mix heavy oil with light oil at a fixed ratio in order to reduce fuel costs, but due to variations in the properties of the received heavy oil and Due to the unequal mixing ratio, it was difficult to find the optimal viscosity for combustion in the engine.

くするようにしたことを特徴とする。An object of the present invention is to provide a constant viscosity fuel oil supply system for determining the optimum viscosity for combustion for heavy oils with varying properties and different mixing ratios. The heavy viscosity fuel oil supply system of the present invention In this system, the fuel oil from the booster pump that supplies fuel oil from the fuel oil regular tank to the engine is supplied to the engine via the heater, and the fuel oil that is not consumed by the engine is transferred to the fuel oil via the fluid restrictor. A return line having a pressure regulating valve is connected between the fuel oil inlet of the booster pump and the fuel oil outlet of the heater to detect the amount of fuel oil consumed by the engine. A fuel gauge is provided, and when the opening degree of the pressure regulating valve increases, the heating temperature of the heater is increased accordingly, and when the value of the fuel consumption gauge becomes large, the heating temperature of the heater is increased accordingly. It is characterized by being made lower.

1 shows a booster pump for supplying fuel oil from a fuel oil regular tank 1. In the present invention, the fuel oil from the discharge port of the booster pump 3 is supplied to the engine 2 through the heater 4, and is consumed by the engine 2. The unused fuel oil is returned to the fuel oil supply side such as the fuel oil regular tank 1 or the stand pipe 1' through the fluid restrictor 5, and is placed between the fuel oil inlet of the booster pump 3 and the fuel oil outlet of the heater 4. A return line 6 is connected to the return line 6, and a pressure regulating valve 7 is inserted into the return line 6. This pressure regulating valve functions to keep the pressure of the line 6, and thus the booster pump discharge pressure, constant at all times by changing the opening degree of the regulating valve when the pressure of the line 6 changes.

Furthermore, a fuel consumption meter, for example, a rank memory detector 10, is attached to the engine 2 to detect the amount of fuel oil flowing into the engine, and a fuel consumption meter, for example, a rank memory detector 10, is installed between the steam supply source 8 and the heater 4, and is opened or closed depending on the value of the rack memory detector 10. A valve 11 is inserted.

に供給する油の粘度を常時一定に保つことができる。Therefore, in the device of the present invention, if the fuel oil consumption cap of the engine 2 is constant, the resistance of the fluid restrictor 5 is proportional to the viscosity of the oil, and as the viscosity of the oil increases, the degree of oil flowing through it decreases. death,
Therefore, the discharge pressure of the booster pump 3 increases. The pressure in the return line 6 connected to the discharge side of the booster pump 3 increases, this is detected by the pressure regulating valve 7 and its opening increases, and the valve 9 is opened in accordance with this opening to remove steam from the steam supply source 8. 'f of steam supplied to heater 4
If it is made to increase, the oil will be heated and the viscosity of the oil will decrease as a result.
The viscosity of the oil supplied can be kept constant at all times.

にする。Furthermore, when the amount of fuel oil consumed by the engine changes due to an increase or decrease in the load on the engine 2, the pressure of the oil flowing through the return line 6 increases or decreases even if the viscosity of the oil does not change, and the valve 9 operates accordingly. . Therefore, in the present invention, when the fuel oil consumption of the engine 2 increases, the rank memory detector 10 detects this and increases the amount of steam flowing through the valve 11 according to the detected value, thereby reducing the viscosity of the oil. When constant, the total amount of steam flowing through both valves 9 and 11 is made equal as a result.

Of course, it can be of a type that is turned on and off compared to the above. Moreover, it goes without saying that the heater 4 may be an electric heater. - As mentioned above, the device of the present invention has the great advantage of being able to constantly supply fuel oil of a constant viscosity to the engine 2 with an extremely simple configuration.
