Problems solved by technology

[0007] However, in places such as cold waters, insufficient heating of the fuel oil in the storage tank 1 to be transported occurs, so the viscosity of the fuel oil flowing in the transport pipe 2 increases, and the suction resistance becomes large. Suction pressure becomes vacuum and becomes difficult to deliver

Embodiment Construction

[0022] figure 1 It is a flow chart showing the heating system of the fuel oil in the storage tank. First, a desired amount of fuel oil such as C-heavy oil is charged into the storage tank 1, and at the same time, a fuel oil (not shown) built in the clarification tank 4 is used. The heated device heats the fuel oil in the clarification tank 4 , and the heated fuel oil flows down into the storage tank 1 through the suction pipe 6 by the operation of the downflow pump 5 . In the storage tank 1, the stored fuel oil and the heated fuel oil flowing down are partially mixed and partially heated to 36°C to 40°C. This heating reduces the viscosity of the fuel oil.

[0023] Next, the partially heated fuel oil in the storage tank 1 passes through the delivery pipe 2 and is delivered to the clarification tank 4 in the direction of the arrow by the operation of the delivery pump 3 . The fuel oil delivered to the clarification tank 4 is heated to a desired temperature by a heating device...

Abstract

The object of the present invention is to improve the power load of the delivery pump and also reduce the suction resistance of the delivery pipe. The solution is to always operate the downflow pump (5) continuously during the delivery by the fuel oil delivery pump (3). At this time, the high temperature oil from the downflow pump (5) is mixed and sent to the The viscosity of the fuel oil absorbed by the transfer pump (3) from the fuel oil from the storage tank (1) decreases, thereby improving the power load of the transfer pump (3), and furthermore, the fuel oil from the storage tank (1) The delivery amount of fuel oil is reduced to the extent equivalent to the amount of flowing oil, the delivery speed from the storage tank is reduced, and the suction resistance of the delivery pipe is also reduced.

Description

technical field [0001] The present invention relates to a heating method of fuel oil in a storage tank of a ship, etc., and more specifically relates to transferring fuel oil such as C heavy oil from a storage tank to a clarification tank through a delivery pipe through a delivery pump and heating it, which will be described here The method of heating the heated fuel oil mixed with the fuel oil flowing down from the clarifier tank through the suction pipe through the suction pipe, in particular, involves improving the power load of the transfer pump and reducing the suction resistance of the transfer pipe A method of heating fuel oil in a storage tank. Background technique [0002] In ships etc., when fuel oil is supplied to the engine, the fuel oil is usually sent from the fuel oil storage tank to the fuel oil clarification tank through the delivery pipe by the delivery pump, where the fuel oil is heated and passed through the fuel oil normal tank. (Fuel tank from which fu...
